PRODUCT INFORMATION
DIURON 80DF is a water dispersible granule to be mixed in water and applied as a
spray for selective weed control of many annual broadleaf and grass weeds in corn,
cotton, sorghum, sugarcane, fruit and nut trees, berries, and certain other crops. It is
also effective in noncrop areas and industrial sites for control of most annual and
many perennial broadleaf and grass weeds.
DIURON 80DF may be applied preemergence. Soils high in clay or organic matter
require higher dosages than soils low in clay or organic matter. Moisture is necessary
to activate DIURON 80DF applied preemergence. Best results occur if rainfall or
sprinkler irrigation occurs within two weeks of application. With favorable moisture
conditions, DIURON 80DF will control weeds over an extended period, after which
secondary weed control procedures such as cultivation and postemergence herbicide
applications should be implemented.
DIURON 80DF may also be used to control emerged weeds. Results are dependent
on amount applied and favorable environmental conditions such as high humidity and
temperatures of 70°F or higher. The addition of an approved non-ionic surfactant
(minimum 80% active), where recommended, increases the contact effectiveness of
DIURON 80DF. When an adjuvant is to be used with this product, Winfield
Solutions, LLG recommends the use of a Chemical Producers and Distributors
Association certified adjuvant.
DIURON 80DF may be used as a directed postemergence application. Contact of
crop foliage and/or fruit with spray or mist must be avoided on the following crops:
artichoke, corn (field), cotton, sorghum (grain), sugarcane and established plantings
of apples, bananas, plantains, blueberries, caneberries, gooseberries, citrus, grapes,
macadamia nuts, olives, papayas, peaches, pears, pecans, walnuts, and certain tree
plantings as injury may occur.
Under the conditions given under "Directions for Use," DIURON 80DF without a
surfactant may be applied over the top of established, dormant or semi-dormant
alfalfa; established asparagus; birdsfoot trefoil (established, dormant), grass seed
crops (established), oats, red clover (established, dormant), sugarcane; wheat; and
pineapple.

Weed species vary in susceptibility to DIURON 80DF and they may be more difficult
to control when under stress. Combinations or tank mixes of DIURON 80DF with
other herbicides (as registered) increase the number of weed species controlled;
consult labels of the companion product for this and other information. Whenever
tank mixing DIURON 80DF with other products, observe all precautions, limitations
and directions on labels of products used in combination with DIURON 80DF.
Since the effect of DIURON 80DF varies with soild, uniformity of application and
environmental conditions, it is suggested that growers limit their first use to small
areas.
USE PRECAUTIONS
Injury to or loss of desirable trees or other plants may result from failure to observe
the following: Do not apply except as directed on this label. Do not empty
application equipment on or near desirable plants or trees, or to where their roots
may extend, or to where the chemical might be washed or otherwise moved into
contact with their roots. Do not use on any home plantings nor on lawns, walks,
driveways, tennis courts, or similar areas. Do not allow spray to drift onto desirable
plants. Do not mix/load or use near wells including abandoned wells, drainage wells
and sink holes. Avoid storage of pesticides near well sites. Keep from contact with
fertilizers, insecticides, fungicides and seeds. Calibrate sprayers only with clean water
away from well sites.
Thoroughly clean all traces of DIURON 80DF from application equipment immediately
after use. Flush tank, pump, hoses, and boom with several changes of water after
removing nozzle tips and screens (clean these parts separately).
RESISTANCE
When herbicides that affect the same biological site of action are used repeatedly
over several years to control the same weed species in the same field, naturally-
occurring resistant biotypes may survive a correctly applied herbicide treatment,
propagate, and become dominant in that field. Adequate control of these resistant
weed biotypes cannot be expected. If weed control is unsatisfactory, it may be
necessary to retreat the problem area using a product affecting a different site of
action.
To better manage herbicide resistance through delaying the proliferation and possible
dominance of herbicide resistant weed biotypes, it may be necessary to change
cultural practices within and between crop seasons such as using a combination of
tillage, retreatment, tank-mix partners and/or sequential herbicide applications that
have a different site of action. Weed escapes that are allowed to go to seed will
promote the spread of resistant biotypes.
It is advisable to keep accurate records of pesticides applied to individual fields to
help obtain information on the spread and dispersal of resistant biotypes. Consult
your agricultural dealer, consultant, applicator, and/or appropriate state agricultural
extension service representative for specific alternative cultural practices or herbicide
recommendations available in your area.

SPRAY DRIFT MANAGEMENT
Avoiding spray drift at the application site is the responsibility of the applicator.
The interaction of many equipment and weather-related factors determine the
potential for spray drift. The applicator and the grower are responsible for
considering all these factors when making decisions. The following spray drift
management practices are recommended to avoid off-target drift movement from
aerial applications to agricultural field crops. These requirements do not apply to
forestry applications, public health uses or to applications using dry formulations.
• The distance of the outer most nozzles on the boom must not exceed % the
length of the wingspan or rotor.
• Nozzles must always point backward, parallel with the air stream, and never be
pointed downwards more than 45 degrees. Where states have more stringent
regulations, they should be observed.
The applicator should be familiar with and take into account the information
covered in the aerial drift reduction advisory information.
Importance of Droplet Size: The most effective way to reduce drift potential is to
apply large droplets. The best drift management strategy is to apply the largest
droplets that provide sufficient coverage and control. Applying larger droplets
reduces drift potential but will not prevent drift if applications are made improperly
or under unfavorable environmental conditions (see Wind, Temperature and
Humidity, and Temperature Inversions).

r r

Controlling Droplet Size
Volume - Use high flow rate nozzles to apply the highest practical spray volume.
Nozzles with higher rated flows produce larger droplets.
Pressure - Use the lower spray pressures recommended for the nozzle. Higher
pressure reduces droplet size and does not improve canopy penetration. When
higher flow rates are needed, use higher flow rate nozzles instead of increasing
pressure.
Number of Nozzles - Use the minimum number of nozzles that provide uniform
coverage.
Nozzle Orientation - Orienting nozzles so that the spray is released backwards,
parallel to the air stream, produces larger droplets than other orientations.
Significant deflection from horizontal will reduce droplet size and increase drift
potential.
Nozzle Type - Use nozzle type that is designed for the intended application. With
most nozzle types, narrower spray angles produce larger droplets. Consider
using low-drift nozzles. Solid stream nozzles oriented straight back produce
larger droplets than other nozzle types.
Boom Length: For some use patterns, reducing the effective boom length to less
than 3/i of the wingspan or rotor length may further reduce drift without reducing
swath width.
Application Height: Applications should not be made at a height greater than 10
feet above the top of the largest plants unless a greater height is required for
aircraft safety. Making applications at the lowest height that is safe reduces
exposure of droplets to evaporation and wind.
Swath Adjustment: When applications are made with a crosswind, the swath will
be displaced downward. Therefore, on the up and downwind edges of the field,
the applicator must compensate for this displacement by adjusting the path of the
aircraft upwind. Swath adjustment distance should increase with increasing drift
potential (higher wind, smaller drops, etc.).
Wind: Drift potential is lowest between wind speeds of 2-10 mph. However,
many factors, including droplet size and equipment type determine drift potential at
any given speed. Application should be avoided below 2 mph due to variable wind
direction and high inversion potential. NOTE: Local terrain can influence wind
patterns. Every applicator should be familiar with local wind patterns and how they
affect spray drift.
Temperature and Humidity: When making applications in low relative humidity, set
up equipment to produce larger droplets to compensate for evaporation. Droplet
evaporation is most severe when conditions are both hot and dry.
Temperature Inversions: Applications should not occur during a temperature
inversion because drift potential is high. Temperature inversions restrict vertical air
mixing, which causes small suspended droplets to remain in a concentrated cloud.
This cloud can move in unpredictable directions due to the light variable winds

c JL
common during inversions. Temperature inversions are characterized by increasing
temperatures with altitude and are common on nights with limited cloud cover and
light to no wind. They begin to form as the sun sets and often continue into the
morning. Their presence can be indicated by ground fog; however, if fog is not
present, inversions can also be identified by the movement of smoke from a ground
source or an aircraft smoke generator. Smoke that layers and moves laterally in a
concentrated cloud (under low wind conditions) indicates an inversion, while smoke
that moves upward and rapidly dissipates indicates good vertical air mixing.
Sensitive Areas: The pesticide should only be applied when the potential for drift
to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat
for threatened or endangered species, non-target crops) is minimal (e.g. when wind
is blowing away from the sensitive areas).

APPUCATION DIRECTIONS
Postemergence Use (Emerged Seedling Weeds): DIURON 80DF, at specified rates,
controls annual weeds such as annual morningglory, barnyardgrass (watergrass),
crabgrass, crowfoot, goosegrass, pigweed and purslane. Addition of an approved
non-ionic surfactant (minimum 80% active) to the spray, where recommended,
increases contact effectiveness. Best results are obtained on succulent weeds
growing under conditions of high humidity and temperatures of 70°F or higher.
Equipment Spray Volumes and Pressures
Ground Application: Use a boom power sprayer properly calibrated to a constant
speed and rate of delivery. Openings in screens should be equal to or larger than
50 mesh. Continuous agitation in the spray tank is required to keep the material in
suspension. Agitate by mechanical or hydraulic means; if by-pass or return line is
used, it should terminate at bottom of tank to minimize foaming. Avoid overlapping
and shut off spray booms while starting, turning, slowing or stopping, or injury to
the crop may result.
Aerial Application: For alfalfa, barley (winter), cotton (preplant or preemergence
only), grass seed crops (PNW only), wheat (winter), and rights-of-way, application
may be made by aircraft (3 to 10 gals, per acre) unless otherwise noted; avoid
overlapping of spray swath and avoid application under conditions where excessive
drift may occur. Where land is bedded, make application parallel to rows. For all
other crops other than those listed directly above, aerial application is prohibited.
Spray Preparation
Mix proper amount of DIURON 80DF into necessary volume of water; where use of
a surfactant is recommended, dilute with 10 parts of water and add as last ingre-
dient to nearly full tank.
Use Rates
All dosages are expressed as broadcast rates; for band treatment, use proportionately
less. For example, use 1/3 of the broadcast rate when treating a 14" band where
row spacing is 42". Where a range of dosages is given, use the lower rate on coarse
textured soils (low in clay or organic matter) and the higher rate on the fine textured

r r sr10.
soils (high in clay or organic matter); for post emergence application, use the lower
rate on smaller weeds and the higher rate on larger weeds.
Soil Limitations
Crop injury may result if used on sand, loamy sand, gravelly soils or exposed
subsoils. Do not use on pecans where organic matter is less than 0.5%; nor on
alfalfa, apples, artichoke, barley (winter), citrus, cotton, grapes, oats, olives, papayas,
peaches, pears, sorghum, sugarcane, walnuts, and wheat (winter) where organic
matter is less than 1%; nor on blueberries, birdsfoot trefoil, caneberries,
gooseberries, macadamia nuts and peppermint where organic matter is less than 2%.
Preemergence weed control will be reduced on high organic matter soils (greater than
5%, such as peat or muck).
Replanting
Unless otherwise directed, do not replant treated areas to any crop within 2 years
after last application as injury to subsequent crops may result. NOTE: For crops
grown in the arid west, reductions in normal irrigation practices for the crop in
production or a summer fallow period without supplemental irrigation may require the
crop rotation intervals to be extended. When such conditions occur, a field bioassay
should be completed prior to planting any desired crop. A successful bioassay means
growing to maturity a test strip of the crops intended for production. The test crops
strip should cross the entire field including knolls, low areas, and areas where any
berms were located. The results of this bioassay may require the rotation intervals to
be extended.
FIELD CROPS
(See "Soil Limitations")
A good seedbed must be prepared before preemergence use of DIURON 80DF as
crop injury may result if application is made to ground which is cloddy or compacted
resulting in improperly planted seed. Plant seed to depth specified. Unless otherwise
directed, surface of the soil should not be cultivated or disturbed after application and
before emergence of the crop as weed control may be reduced and crop injury may
result. However, if moisture is insufficient to activate the herbicide, a shallow
cultivation (rotary hoe preferred) should be made after emergence of crops while
weeds are small enough to be controlled by mechanical means.
ALFALFA: Treat only stands established for 1 year or more. Do not apply to seedling
alfalfa nor to alfalfagrass mixtures; do not apply to alfalfa under stress from disease,
insect damage, shallow root penetration (such as on shallow hard pans), alkali spots;
nor to flooded fields as crop injury may result. Do not spray on snow-covered or
frozen ground. Do not apply more than 3 pounds/acre per year. Apply a maximum of
one application per year.
Idaho, Oregon, Washington: Use 1.5 to 3 pounds per acre. Apply in fall after alfalfa
becomes dormant but no later than mid-December.

r r a
11California (Dormant and Semi-Dormant Varieties): Use 1.5 to 3 pounds per acre; for
control of volunteer alfalfa. Apply in fall or winter after alfalfa becomes dormant or
semi-dormant, but before growth begins in the spring. Crop injury may result if
application is made to actively growing alfalfa. For best results, apply before weeds
have emerged or become established (2" in height or diameter). Control of
established weeds is improved by applying DIURON 80DF with a suitable contact
herbicide registered for such use. Sufficient rainfall for soil activation of DIURON
80DF is unlikely in California after February 1. Treated areas may be replanted to any
crop after one year from last application if rate does not exceed 2 pounds per acre.
Arizona, Nevada: Use 1.5 to 3 pounds per acre; apply in fall after alfalfa becomes
dormant but no later than January.
Eastern Colorado, Kansas: For control of tansy mustard, apply 1 pound per acre
shortly after emergence of mustard in the fall or winter; use 2 pounds per acre if
weeds are 2" to 4" high. Alternatively, if other annual weeds are present, apply 2 to
3 pounds per acre in February or March.
Other Areas Where Alfalfa Becomes Winter Dormant: Use 1.5 to 3 pounds per acre
(1% to 2 pounds per acre east of Appalachian Mountains). Apply in March or early
April, but before spring growth begins.
ARTICHOKE-Califomia: Apply 2 to 4 pounds per acre in late fall or early winter after
the last cultivation. Apply before weeds germinate or to emerging seedlings. Direct
spray to cover the area between the rows and at the base of artichoke plants,
keeping contact with crop plants at a minimum.
ASPARAGUS: Apply as a band or broadcast treatment. Do not apply to young
plants during the first growing season (except as noted below), nor to newly seeded
asparagus, nor on plants with exposed roots as severe injury may result.
Preemergence weed control will be reduced on high organic matter soils (greater than
5%).
Established Plantings: On light sandy soils and other soils low in clay or organic
matter, apply 1 to 2 pounds per acre. On soils high in clay or organic matter, use 2
to 4 pounds per acre. Two applications may be used; the first application should be
made before weeds become established but no earlier than 4 weeks before spear
emergence and no later than the early cutting period (if weeds are controlled into the
cutting period by cultural practices, application may be delayed until immediately
after the last cultivation); a second application may be made immediately following
completion of harvest period provided rainfall is expected. When two applications are
used in one season, do not exceed 3 pounds per acre per application. In Washington
(irrigated crop), apply a single treatment of 4 pounds per acre. If treatment is delayed
until late winter or early spring, incorporation of the chemical in the top 1" to 2" of
soil may substitute for lack of rain to activate the herbicide.
Newly Planted Crowns-California (San Joaquin Delta): Make a single application of 2
to 4 pounds per acre on soils high in clay or organic matter; use the lower rate on

r r
12
clay loams and the higher rate on peat soils. Do not use on soils containing less than
2% organic matter. Soil must be settled by rainfall or irrigation prior to treatment.
Do not treat crowns planted to a depth of less than 2".
BARLEY, WINTER (Drill-Planted)-Western Oregon and Western Washington: Make a
single application of 1 .5 to 2 pounds per acre as soon as possible after planting but
before emergence of barley. Do not replant treated areas to any crop within 1 year
after last application as injury to subsequent crops may result.
BIRDSFOOT TREFOIL (Lotus)-Western Oregon: Treat only stands established for at
least 1 year. Do not apply to seedling trefoil as injury may result. Make a single
application of 2 pounds per acre when trefoil is dormant (October 15 to December
15). Do not replant treated areas to any crop within 1 year after last application as
injury to subsequent crops may result.
CORN (Field) Postemergence: Make a single application of 0.75 pound in
combination with non-pressure nitrogen solution. If nitrogen solution is not used,
apply 1 pound per acre; add 1 pint of an approved non-ionic surfactant per 25 gallons
of spray. Apply as a directed spray when corn is at least 20" high and weeds are no
taller than 3". Do not apply over top of corn. Do not replant to any crop within 1
year, except that cotton, corn and grain sorghum may be planted the spring following
treatment.
Preemergence-Arkansas, Louisiana, Mississippi, and Tennessee: Make a single
application of 0.67 to 1 pound per acre as a broadcast or band treatment after
planting but before corn emerges. Plant corn at least 11/i" deep. Do not replant
treated areas to crops other than corn or cotton within 4 months following band
treatment and 6 months following broadcast treatment as crop injury may result.
COTTON: During a single season, do not exceed the following amounts of DIURON
80DF per acre as injury to subsequent crops may result; 1 pound on sandy loam; 1.8
pounds on clay loam; and 2.75 pounds on clay. Do not spray over the top of cotton
plants. Do not apply to sand or loamy sand soils. Do not use on soils with less than
1% organic matter as crop injury may result. Injury may occur if DIURON 80DF is
used in conjunction with soil-applied organophosphate pesticides. Do not allow
livestock to graze treated cotton. Do not make more than 3 applications per year. A
minimum retreatment interval is 21 days.
Preplant-Arizona and California: Use DIURON 80 DF alone, or apply as a separate
operation following preplant broadcast treatment with trifluralin products
(incorporated according to direction on the trifluralin label). Apply DIURON 80DF as a
broadcast spray after beds are formed, pre-irrigated, and final seedbeds prepared.
Prior to planting, drag-off the tops of the beds and plant in moist soil not treated with
DIURON 80DF. Treated soil is returned to the bed after planting when irrigation
furrows are re-formed after cotton has emerged. If more than two furrow ing-out
operations are made prior to lay-by, or deep furrows are made early, weed control
may be reduced in furrow bottoms. Use at the following rates:

1 to 1.25 Ibs.
Note: Seedling disease may weaken plants and increase the possibility of injury from
the use of trifluralin followed by DIURON 80DF. These treatments should be used
only in conjunction with a standard fungicide seed treatment plus a good
supplemental soil fungicide program.
Preplant (except Arizona and California): Diuron 80DF may be used for burndown of
existing annual weeds and residual control of weeds prior to planting cotton.
Complete any planned tillage prior to application. Apply herbicide treatments before
weeds germinate or before weed seedlings are more than 2 inches tall. If weeds are
emerged prior to application, the addition of a non-ionic surfactant is recommended.
Tillage following application should be avoided to prevent incorporation of the
herbicide into the cotton seed germination zone which may result in crop injury.
Dragging treated soil from beds will concentrate the herbicide in middles and reduce
residual weed control on the beds.
Apply Diuron 80DF at 1 to 2 pounds per acre from 15 to 45 days prior to anticipated
planting. Refer to the table below for use rates in preplant applications. Do not
exceed suggested use rates for individual soil textures shown in the table below. If
less than the maximum rate of application for a given soil is applied preplant,
subsequent preemergence applications of Diuron 80DF may be made. However, the
total combined application rate for Diuron 80DF applied preplant and preemergence
may not exceed the maximum suggested use rate for either application method.

Preemergence application of herbicides with a similar mode of action to that of diuron
following preplant application of Diuron 80DF may result in cotton injury. When
preplant applications of Diuron 80DF are followed by preemergence applications of
herbicides with a similar mode of action, e.g., products containing fluometuron, the
product containing fluometuron should be used at the minimum rate of application for

f ir
14
the soil under consideration in order to reduce potential for crop injury. This is most
critical where applications of Diuron 80DF are made less than 30 days preplant, on
coarse textured soils, and on soils low in organic matter. The risk of injury from
preplant applications of Diuron 80DF is reduced where substantial rainfall (> 0.5")
occurs between application and planting. Read and follow any additional precautions
on the Diuron 80DF label when using this product for preplant weed control in
cotton.
Preplant Tank Mixes: When emerged weeds taller than 2 inches or weeds not listed
on the Diuron 80DF label are present, Diuron 80DF may be tank mixed with other
products labeled for preplant applications in cotton, including paraquat and
glyphosate. The addition of dry spray grade ammonium sulfate at the rate of 2.0%
w/w (17 pounds per 100 gallons finished spray solution) is suggested to enhance
performance of Diuron 80DF plus glyphosate tank mixes.
Replanting: Only cotton and corn may be planted within 6 months of preplant
applications of Diuron 80DF. To avoid crop injury following replanting, avoid
disturbing the original bed.
Preemergence-U.S., except Arizona, California: Use DIURON 80DF alone or apply as
a separate operation following preplant treatment with trifluralin. Apply after planting
but before cotton emerges. Do not treat cotton in deep furrows as crop injury may
result; use only where cotton is planted on flat or raised seedbeds. Shallow
incorporation (no deeper than %") with a rotary hoe or similar equipment following
planting usually improves results especially during dry weather. A wide press wheel
should be used on the planter to provide a level seedbed for subsequent early season
postemergence treatments. If moisture is insufficient to activate DIURON 80DF or if
soil becomes crusted before crop emerges, a shallow rotary hoeing (no deeper than
%") should be made before weeds become established.
Diuron 80DF should not be applied preemergence following application of the
maximum rate for a given soil applied preplant. If less than the maximum rate is used
preplant, additional Diuron 80DF may be applied preemergence. However, the total
amount of Diuron 80DF applied preplant and preemergence must not exceed the
maximum suggested use rate for either preplant or preemergence applications.
DIURON 80DF Alone: Make a single application as a broadcast or band spray, using
the following broadcast rates; for band treatment, use proportionately less.

Postemergence-U.S.: Apply only as a directed spray to cover weed foliage; adjust
nozzles to minimize contact of cotton leaves with spray or drift, or crop injury may
result. Applications may also be made in hooded/shielded sprayers. Do not spray
over top of cotton.
Early Season-Apply when cotton is at least 6" tall and when weeds are actively
growing and do not exceed 2" in height. Apply as a band treatment at following
rates: for each 25 gallons of spray, add 1 pint of an approved non-ionic surfactant.
Two applications may be made if needed.

in height, add 1.65 to 2 pounds active MSMA to above spray mixture. If MSMA is
used, do not apply after first bloom.
For enhanced weed control in hooded/shielded sprayer applications, add MSMA as
suggested above; or paraquat or glyphosate according to label recommendations.
Consult product labels for specific recommendations and precautions for hooded
sprayer applications.
Late Season (Lay-By)-Apply 1 to 1.5 pounds per acre (1 to 2 pounds in Arizona and
California) when cotton is at least 12" tall (at least 20" tall for Pima S-2). For control
of germinating weed seedlings, apply to soil beneath cotton plants and between rows
immediately after last cultivation. In irrigated cotton, best weed control is obtained if

r
16
the field is irrigated within 3 to 4 days after application; thoroughly wet the surface
of the ground over the row to carry the herbicide into the root zone of germinating
weeds.
Alternatively, for control of emerged annual weeds (up to 4" in height) at lay-by time,
make a single application in combination with an approved non-ionic surfactant (1
pint per 25 gallons spray), or use 0.5 to 0.75 Ib./acre plus surfactant and repeat later
if needed.
Replanting: If initial seeding fails to produce a stand, cotton may be replanted in soil
treated preplant or preemergence with DIURON 80DF alone or following trifluralin.
Wherever possible, avoid disturbing original bed. If necessary to rework soil before
replanting, use shallow cultivation such as discing; do not relist or move soil into the
original drill area. Plant seed at least 1" deep. Do not retreat field with a second
preplant or preemergence application during the same crop year as injury to the crop
may result.

within one year after last application as
injury to subsequent crops may result.
For subsequent crops in fields where trifluralin is used, follow instructions on the
trifluralin label.
GRASS SEED CROPS (Perennial) Except as noted, apply only to established plantings
at least 1 year old. Apply a single application per year at up to 3 pounds per acre.
May be applied by aerial application in the Pacific Northwest only.
Colorado, Kansas, Missouri, New Mexico, and Oklahoma: On sand bluestem, side
oats grama and switchgrass, apply 2 to 3 pounds per acre during the dormant period
shortly before weed seedlings emerge. Do not apply after crop begins growth in the

c
17
spring as crop injury may result. In fields where ash residues have accumulated from
burning straw, use 3 pounds per acre; spread unburned chaff or straw with a harrow
or chopper before application.
Western Oregon, Western Washington: On alta fescue, Astoria bentgrass, Highland
bentgrass, Kentucky bluegrass (Merion bluegrass), and orchardgrass, apply 2 to 3
pounds per acre between October 1 and November 15. In fields where ash residues
have accumulated from burning straw, use 3 pounds per acre; spread unburned chaff
or straw with a harrow or chopper before application. For best results, apply as soon
as possible after fall rains start. Established weeds (beyond 2 to 4 leaf stage) should
be removed prior to treatment.
Well established vigorous stands of spring-planted alta fescue, Kentucky bluegrass,
and orchardgrass may be treated the following fall provided the crop is planted before
April 1 and treatment is not applied before October 15; use 2 pounds per acre.
Oregon, Washington: For use in newly planted bentgrass, fine fescue, Kentucky
bluegrass, perennial ryegrass, orchardgrass, and tall fescue. During planting
operation, spray a suitable brand of activated charcoal as a 1" band on soil surface at
a rate of 300 pounds per acre (broadcast basis; equivalent to 15 pounds per acre of
crop where row spacing is 20"). Mount nozzles to apply directly over seed rows to
prevent crop injury. Follow with DIURON 80DF as a single broadcast spray at a rate
of 21/£ or 3 pounds per acre; apply as soon as possible after planting but before crops
or weeds emerge and before rains or sprinkler irrigation. Fall or spring plantings may
be treated; best results usually occur with early fall plantings. Treatment will not
control downy brome or wild oats.
Oregon, Washington: Apply in the fall to perennial ryegrass at the rate of 1 to 2
pounds per acre and to tall fescue at the rate of 2 to 3 pounds per acre. Use a
sufficient volume of water, a minimum of 25 gallons per acre, for thorough coverage
of weed foliage. For best results, make applications at the onset of the fall rains and
before weeds have become established (typically October 1 through November 15).
Established weeds beyond the 2-4 leaf stage should be removed prior to treatment.
Apply only to well established vigorous stands. Do not apply to perennial ryegrass
stands less than 1 year old. Use mechanical agitation and avoid overlap of spray
patterns. Weed control efficacy may be reduced in fields where ash residues have
accumulated from burning straw.
Eastern Washington, Eastern Oregon: Established Perennial Bluegrass and fescue-
Broadcast 1 to 3 pounds of DIURON 80DF per acre in enough diluent to get even
distribution. Apply in spring before rapid growth begins of the Bluegrass and when
the windgrass is still small (1-4 leaf). Do not use on coarse (sandy) textured soils.
Annual Ryegrass for the Creation of Rows: Apply 1 to 2 pounds per acre as a
directed or shielded spray so the intended crop row area is not treated. These
applications should be made where excessive populations of annual ryegrass are
anticipated to volunteer from previous crops. Applications can be made as a
directed/shielded spray during seeding or after emergence of annual ryegrass. These

r
18
applications generally will occur between October 1 and January 15. Diuron 80DF is
most effective when applied before annual ryegrass volunteer plants have more than
2 leaves. If larger plants are to be treated, addition of a labeled postemergence
herbicide will provide more effective control. Adjust nozzle heights and spacing to
allow the establishment of the desired row width (generally about 3 inches) and
spacing (generally 9 to 12 inches). Use of low pressure nozzles, shielded nozzles, or
drop nozzles to reduce spray movement into the intended crop row area is
recommended.
Fine Fescue Grass Seed Crops (including chew ings, creeping red and hard fescue
types): For the suppression of rattail fescue, apply 1 to 2 pounds per acre on soils
having at least 1 % organic matter. Do not use on sand, loamy sand, gravelly soils or
exposed subsoils.
Crop Stage and Application Timing: Diuron 80DF is for use on healthy, vigorous
stands of fine fescue. Diuron 80DF can be applied to stands established at least 1
year or to new plantings that have been established for at least 6 months and have a
minimum of eight tillers at time of application.
Apply in fall before grass weeds are beyond the one to two leaf stage and before
broadleaf weeds are larger than 1 to 2 inches tall or across. Use the high end of the
rate range for large weeds or where weed populations are high.
Approximately Vz to 1 inch of rainfall or sprinkler irrigation is needed to move Diuron
80DF into the weed zone before weeds develop an established root system. Weeds
larger than the size indicated or those having a well established root system before
Diuron 80DF is properly activated by rainfall/irrigation may not be adequately
controlled.
Weed control may be reduced by heavy straw residues or ash from field burning.
Tank Mixes: Diuron 80DF can be applied either alone or in a program involving tank
mixes with other herbicides and adjuvants. When using a tank mix with other
herbicides, use 1 to 1-1/2 pounds per acre unless prior experience indicates it is safe
to use higher rates. Tank mixes with other herbicides can increase the risk of crop
injury. When using a tank mix for the first time, limit use to a small area to determine
safety before treating large areas.
Use Precautions: Do not replant treated areas to any crop within 2 years of last
application as injury to subsequent crops may result. Do not apply to snow covered
or frozen ground as injury to the crop or poor weed control may result. Do not treat
stands lacking in vigor due to poor fertility, environmental stress, insect or disease or
damage from other herbicides.

PERENNIAL RYEGRASS, TALL FESCUE, KENTUCKY BLUEGRASS, AND FINE
FESCUE (Grown for Seed)
For control of certain broadleaf weeds and annual grasses, apply this product only to
well established vigorous stands of grasses as directed below. Use sufficient water
(a minimum of 25 gallons per acre) for thorough coverage of weed foliage. For best
results, make application at the onset of fall rains and before weeds become
established (typically October 1 through November 15). Weeds beyond the 2- to 4-
leaf stage will usually not be controlled. Use higher rates within the range listed
when treating larger weeds and heavier weed infestation. Weed control may be
reduced where straw or ash residues have accumulated on the soil surface. Lack of
moisture to activate the herbicide may reduce weed control;. Tank mixtures or
sequential treatments with other herbicides may reduce crop tolerance and increase
risk of crop injury. When using DIURON 80 DF in a tank mix or in a sequential
treatment with other herbicides, do not use the maximum rates listed below unless
compatibility and the potential for phytotoxicity have been evaluated. Crop tolerance
may be reduced and the likelihood of crop injury may increase when crop is under
stress caused by weather, diseases, and insects.
Perennial Ryegrass (Established) (Oregon Only): Apply 1 to 2 pounds per acre per
season (October 1 through mid-January) to control seedling grasses and broadleaf
weeds such as annual bluegrass and others named on this label.
Tall Fescue (Established (Oregon Only): Apply 2 to 3 pounds per acre per season
(October 1 through mid-January) to control seedling grasses and broadleaf weeds
such as rattail fescue and others named on this label.
Kentucky Bluegrass (Established stands east of the Cascade Mountains) (Oregon,
Washington Only): Apply 1 .5 to 3 pounds per acre per season (October 1 through
mid-January for suppression of rattail fescue and certain other seedling grasses and
broadleaf weeds named on this label. Downy brome is not controlled. Do not use on
Poa trivialis grass seed varieties.
Fine Fescue (Illahee, Rainier, Chew ings, and related varieties including Hard Fescue)
(Established stands west of the Cascade Mountains) (Oregon Only): Apply 1 to 2
pounds per acre for suppression of rattail fescue and certain other seedling grasses
and broadleaf weeds named on this label. Make only 1 application per year. Do not
use this product more than two years in succession in the same field.
OATS (Drill-Planted)
Do not replant treated areas to any crop within one year after last application as
injury to subsequent crops may result.
Spring Oats— Idaho, Eastern Oregon, Eastern Washington: Use in areas where
average annual rainfall exceeds 16". Make a single application of 1 to 1.5 pounds
per acre after planting, either before or after oats emerge but within 6 weeks of
planting. Best results are usually obtained when application is made 3 to 4 weeks
after planting. Apply before weeds are 3" to 4" tall.

20
Winter Oats and Mixtures with Peas or Vetch-Western Oregon and Western
Washington: Make a single application of 1.5 to 2 pounds per acre as soon as
possible after planting but before emergence of the crop.
PEPPERMINT (Washington, Oregon, Idaho)
Apply Diuron 80DF at 0.75 to 1 pound per acre on soils having 1.0% to 2.0%
organic matter.
Apply Diuron 80DF at 1 to 2 pounds per acre on soils having 2.1% to 3.0% organic
matter.
Apply Diuron 80DF at 2 to 3 pounds per acre on soils having more than 3.0%
organic matter.
Use Precautions: Do not apply to stands of mint suffering from stress due to low
fertility, drought, winter injury, insects, disease or damage from other herbicides or
other causes. Do not apply to snow covered or frozen ground as injury to the crop or
poor weed control may result. Do not apply to sand, loamy soil, gravelly soils or
exposed subsoils. Do not apply to soils that have a high salt content and/or high
water table or poor drainage that retards mint root development resulting in a shallow
root system. Do not apply to soils having less than 1% organic matter.
Application Timing: Apply Diuron 80DF to established (at least one year) stands of
mint during the late winter dormant period or after flaming in the spring prior to the
emergence of new growth. Do not cultivate after application. If weeds are present
at time of application, the use of a surfactant at 0.25% volume/volume or crop oil
concentrate at 1.0% volume/volume may be used to increase the performance of
Diuron 80DF postemergence to weeds.
Tank Mixes and Sequential Treatments: Diuron 80DF can be applied either alone or
in a program involving tank mixes and/or sequential treatments with other herbicides
and adjuvants providing Diuron 80DF is not applied to actively growing mint plant.
When using a tank mix with other herbicides, use the lower end of the Diuron 80DF
use rate range unless prior experience indicates it is safe to use higher rates. Tank
mixes and sequential treatments with other herbicides can increase the risk of crop
injury. When using a certain tank mix or sequential treatment for the first time, limit
use to a small area to determine safety before treating large areas.
RED CLOVER-Western Oregon
Make a single application of two pounds per acre on established red clover (at least 9
months). Apply DIURON 80DF when red clover is dormant (October 15 to December
15). Do not apply to seedling red clover, and do not replant treated area to any crop
within one year after last application as injury to subsequent crops may result.
Treatment will control annual weeds such as bluegrass, chickweed, hawksbeard,
rattail fescue, rye grass, and velvet grass.

11vr21
SORGHUM (GRAIN)--Southwestern States
Apply 0.25 to 0.5 pound per acre; add 1 pint approved non-ionic surfactant per 25
gallons of spray. Apply as a directed post emergence broadcast or band spray after
sorghum is 15" tall to control weeds 2" to 4" in height. Do not spray over top of
sorghum. Use the lower rate on broadleaf weeds up to 2" tall; use the higher rate on
grasses up to 2" and broadleaved weeds up to 4" tall. When the lower rate is used,
a second application may be made if needed provided the amount applied in one crop
year does not exceed 0.5 pound per acre. Treatment of weeds under drought stress
is usually ineffective.
Do not replant treated areas to crops other than cotton or corn within 4 months
following band treatment and 6 months following broadcast treatment as crop injury
may result.
SUGARCANE
To prevent possible crop injury on new cane varieties, test tolerance to DIURON
80DF prior to adoption as field practice. Do not treat sugarcane growing on thinly
covered subsoils or rocky areas as crop injury may result. Temporary chlorosis of the
crop may result from application over emerged cane. Application over emerged cane
should be made only as directed below, without the addition of a surfactant or crop
oil concentrate. To minimize chlorosis, use directed postemergence sprays.
Diuron 80DF may be applied as a directed spray (including hooded and shielded
spray) in combination with labeled paraquat formulations. Consult the label of the
tank mix partner for rates and timings of application, restrictions, precautions.
Florida: Preemergence-For high organic soils, apply 2 to 4 pounds per acre as a
broadcast or band spray prior to weed emergence after planting or after harvesting
plant crop (for ratoon crop). Post emergence-Make 1 to 2 applications of 2 pounds
per acre as needed by directed spray inter-row. Alternatively, for panicum control,
make up to 3 applications of 0.5 to 1 pound per acre as a directed spray after cane
has emerged but before panicum exceeds 2" in height; add 1 quart of an approved
non-ionic surfactant per 100 gallons of spray. Adjust nozzles to spray beneath cane
plants and between rows to cover weed foliage and to minimize contact of cane
leaves with spray drift. Do not apply more than 6 pounds total per acre between
planting (or ratooning) and harvest.
Hawaii: Apply 2 to 6 pounds per acre as a broadcast spray prior to weed emergence
after planting or after harvesting plant crop or ratoon crop. Sequential applications of
2 to 4 pounds per acre may be made as a broadcast spray over emerged cane or by
directed spray inter-row.
If weeds are emerged, add a surfactant to the spray at the rate of 1 to 2 quarts per
100 gallons and apply as a directed spray. Do not spray over the top of cane. Do
not apply more than 3 treatments nor more than 12 pounds total per acre between
planting (or ratooning) and harvest. Treated areas may be planted to sugarcane or
pineapple one year after last application.

13
Tr22
Puerto Rico: Apply 4 to 8 Ibs/acre as a broadcast spray prior to weed emergence
after planting or after harvesting plant crop or ratoon crop. A second and third
application of 2 to 4 Ibs./acre may be made as a broadcast spray over emerged cane
or by directed spray inter-row.
If weeds are emerged, add a surfactant and apply as a directed spray. Do not spray
over the top of cane. Do not apply more than 3 treatments nor more than 10 pounds
per acre in Puerto Rico between planting (or ratooning) and harvest. Treated areas
may be planted to sugarcane or pineapple one year after last application.
Louisiana, Texas: Apply 3 to 3.75 pounds per acre. Diuron 80DF may be applied as
a broadcast spray after planting and following the harvest of sugarcane. Diuron
80DF may also be applied broadcast in late winter. Application is best when made
prior to weed emergence.
Diuron 80 DF may be applied as a post-directed spray immediately after the last
cultivation. Direct the spray application to the base (no more than 1/3 the plant
height) of the sugarcane plants. When.small weeds (3 inches or less) are present at
application, add a surfactant at 0.25% v/v or crop oil concentrate at 1.0% v/v to the
spray mix.
Use Precautions: Temporary leaf yellowing may occur following the application. Do
not apply more than 7.5 pounds per acre broadcast per year. For band application,
reduce the above broadcast rates proportionately to the width of the band using the
following formula:
Band width in inches , , , ,X Broadcast volume per acre - Band volume per acre
Row width in inches
WINTER WHEAT
Crop injury may result where severe winter stress, disease or insect damage follows
application. Winter-sensitive varieties may be less tolerant of DIURON 80DF than
winter-hardy varieties. Crop injury may also result from failure to observe the
following: Do not use on sand or loamy sand soils, nor on gravelly or sandy loams
low in organic matter (less than 1%), nor on thinly covered or exposed subsoil areas
(clay knolls). Do not treat wheat planted less than 1" deep. Do not treat where
winter climatic conditions have caused "heaving" of plants. Do not treat wheat
plants lacking in vigor due to poor emergence, insect damage, disease, high alkalinity
or other causes. Do not apply after wheat has reached the "boot" stage of maturity.
Do check with your county agent or state extension specialist before using DIURON
80DF in combination with surfactants or nitrogen solutions. Do not replant treated
areas to any other crop within 1 year after last treatment (except as noted) as injury
to subsequent crops may result.

23
Idaho, Oregon and Washington-East of Cascade Range:
Areas Where Average Rainfall Exceeds 16 Inches: Make a single application of 1 to
1 .5 pounds per acre.
Fall Treatment: For early fall-planted wheat (seeded before September 10), apply 3
to 6 weeks after planting, but before weeds are 3" to 4" tall. Treatment after
October 1 has generally given best results. Application should not be made after soil
freezes in the fall. Wheat planted in late October should not be treated until the
following spring.
Spring Treatment: Apply as soon as wheat starts to grow in the spring. Treatment
made prior to April 10 will usually give good results provided weed growth is less
than 4" tall. Application later than May 1 may give poor results. Alternatively, make
a single application of 0.5 to 1 pound DIURON 80DF plus 0.25 pound bromoxynil
per acre as a tank mixture, either in the fall after wheat has emerged but before soil
freezes or in the spring as soon as soil thaws; apply before weeds are 2" tall or
across.
Areas Where Average Annual Rainfall is 10 to 16 Inches: After wheat is planted in
fall, make a single application of 1 to 1 .5 pounds per acre when sufficient moisture is
available to germinate wheat seed. Apply before soil freezes and before weeds are
2" tall. Application later than March 1 may give poor results.
Note-lf fall-planted wheat fails to grow due to winter kill or adverse growing
conditions after fall treatment, only fields treated before November 1 may be
replanted to spring wheat. Spring wheat should not be planted before April 1 and
only after deep discing and plowing to a depth of 4" to 6" prior to planting. Do not
retreat field with a second application during the same crop year as injury to the crop
may result.
Oregon and Washington-West of Cascade Range: Make a single application of 1 .5
to 2 pounds per acre as soon as possible after planting. If wheat and weeds have
emerged, apply before weeds are 3" to 4" tall. Alternatively, apply a tank mixture of
Diuron plus bromoxynil as detailed above for "East of Cascade Range".
Other Areas of Oregon and Washington: Make a single application in the spring as
soon as wheat (fall-planted) starts to grow and before weeds are 2" tall. Application
later than May 1 may give poor results.
Central Plains and Midwest: Use 1 to 2 pounds per acre.
Kansas, Oklahoma and Texas: Do not use on sand or sandy loam soils. Use 1 pound
per acre on silt and silt loam soils and 1.5 to 2 pounds per acre on clay, clay loam,
and silty clay loam soils.
Northeast: Use 1 to 1 .5 pounds per acre.

24
FRUIT AND NUT CROPS
(See "Soil Limitations")
Unless otherwise directed, make a single application per year as a directed spray,
avoiding contact of foliage and fruit with spray or drift. Do not graze livestock in
treated orchards or groves.
APPLES
DIURON 80DF Alone-Use only under trees established in the orchard for at least 1
year. Do not treat varieties grafted on full-dwarf root stocks. Apply 4 pounds per
acre in the spring (March through May). In the Far West, treatment may be made in
winter (December through February), or apply 2 pounds per acre as a postharvest
treatment followed by 2 pounds in the spring.
Note: The maximum rate per application is 4 pounds per acre. The maximum
application rate per crop cycle is 4 pounds per acre. Do not apply more than two
application per year. The minimum retreatment interval is 90 days.
DIURON 80DF + Terbacil-Use only under trees established in the orchard for at least
2 years. Apply either in the spring or after harvest in the fall before weeds emerge or
during early seedling stage of weed growth.

the bottom of irrigation furrows, nor trees grown under flat flood or basin irrigation,
as injury to trees may result. Where complete weed control to harvest is desired,
additional weed control measures may be required during the growing season.
Georgia-Apply 2 to 3 pounds per acre in the spring. Repeat application in the fall but
do not use more than 4 pounds per acre per year. Add an approved non-ionic
surfactant at 1 pint per 25 gallons spray mixture to improve control of small,
emerged weeds.
BANANAS AND PLANTAINS-New Plantings
To control annual weeds, apply 1.5 to 3 pounds per acre after planting but before
weeds emerge. Do not apply to loose soil directly over the planting material.

25
Established Plantings: For control of annual and for top-kill of perennials such as
bermudagrass, birdseed grass and guineagrass, apply 3 to 6 pounds per acre plus 1
pint of a suitable surfactant per 25 gallons of spray; avoid contact of plants with
spray or drift as injury may result. When tall, dense weed growth is present, remove
weed growth before application. If application is made to soil free of weeds, omit the
surfactant from the spray. Repeat treatment as needed, but do not apply more often
than 6-week intervals nor more than a total of 12 pounds per acre (broadcast basis)
in a 12-month period.
Note: Do not replant treated areas to any crop within 2 years after last application,
as injury to subsequent crops may result, except that sugarcane or pineapple may be
planted one year after last application.
BLUEBERRIES, CANEBERRIES, AND GOOSEBERRIES
Use only in fields which have been established for at least 1 year. Do not apply to
berries interplanted with fruit trees; do not apply to plants whose roots are exposed
as injury may result. Apply as a band treatment at a base of canes or bushes; for
spring application, apply before germination and growth of annual weeds.
Arkansas, Florida, Georgia, Mississippi, Missouri, New Hampshire, North Carolina,
South Carolina-Blueberries: Apply 1.5 to 2 pounds per acre in the spring and repeat
treatment after harvest in the fall. Add an approved non-ionic surfactant at 1 pint per
25 gallons spray mixture to improve control of small, emerged weeds.
Indiana, Michigan, and Ohio-Blueberries: Apply 2 to 4 pounds per acre in late
spring; alternatively, apply 2 pounds per acre in the fall and repeat at same rate in the
spring. Raspberries: Apply 3 pounds per acre in the spring.
Maine, Massachusetts-Blueberries: Apply 2 pounds per acre in the late spring.
Maryland, New Jersey-Blueberries: For control of winter annuals, apply 2 pounds
per acre in October, November or December, or a single application of 27z pounds per

California-Raspberries, Blackberries, Boysenberries, Dewberries, and Loganberries:
For control of winter annuals, apply 2 pounds per acre in October or November;
repeat at same rate in late spring to control summer annuals. A single application of
3 pounds per acre in January or February will control both winter and summer
annuals in some areas, but the separate fall and spring schedule is preferred.
Western Oregon and Western Washington-Blueberries, Caneberries, and
Gooseberries: Use same schedule as recommended for California.
CITRUS
Time application as indicated for specific areas, except application may be made any
time of the year where sprinkler or flood irrigation can be timed to activate the

r
26
herbicide. Established perennial weeds require other special control procedures.
Aerial application is prohibited.
Diuron 80DF may be applied in citrus in combination with labeled paraquat and
glyphosate formulations. Read and follow specific label instructions, precautions, and
restrictions on the label of the tank mix partner with applying Diuron 80DF in
combination with other products.

(nontillage program) in late fall or early winter. The maximum single application rate is
4 pounds per acre. Alternatively, apply 2 pounds per acre in October or November
and repeat at the same rate in March or April. Subsequent annual applications of 2
to 3 pounds per acre will usually give adequate weed control.
Do not apply more than 8 pounds per treated acre per year. This amount corresponds
to 6.4 pounds of diuron, the active ingredient in this Diuron 80DF.
The maximum allowable use rate for diuron is 6.4 pounds per treated acre per year
inclusive of all diuron formulations used within 1 year.
FLORIDA: Use only as a band application. Do not use "Trunk to Trunk."
East Coast/Flatwoods Areas - (low permeable soils): Apply from 2 pounds per acre
to a maximum of 8 pounds per acre for control of annual broadleaf weeds and annual
grasses. Addition of an approved surfactant will improve control of emerged weeds.
Do not use more than 8 pounds per treated acre in any one application. Do not apply
more than 8 pounds per treated acre per year. This amount corresponds to 6.4
pounds of diuron, the active ingredient in Diuron 80DF. The maximum allowable use
rate for diuron is 6.4 pounds per treated acre per year inclusive of all diuron
formulations used with 1 year.
Ridge Areas - Except Highland Co. - (highly permeable soils): Apply from 2 pounds

Ridge Areas - Highland Co. - (highly permeable soils): Apply from 2 pounds per acre
to a maximum of 4 pounds per acre for control of annual broadleaf weeds and annual
grasses. Addition of an approved surfactant will improve control of emerged weeds.
Do not use more than 4 pounds per treated acre in any one application. Do not apply
more than 6 pounds per treated acre per year. This amount corresponds to 4.8
pounds of diuron, the active ingredient in Diuron 80DF. The maximum allowable use
rate for diuron is 4.8 pounds per treated acre per year inclusive of all diuron
formulations used with 1 year. Do not use at less than 60-day intervals.
Puerto Rico: Make a single application of 4 pounds per acre, or apply 3 to 4 pounds
per acre followed by the same rate 4 to 6 months later. On bearing citrus, apply any
time when seasonal rains are expected; on non-bearing trees, apply when winter
banks are pulled down.
Do not apply more than 4 pounds per treated acre in any one application.
Texas: Apply 2 to 4 pounds per acre for annual weeds; use 4 pounds per acre for
control of Johnsongrass seedlings. Best results accompany application in the spring;
well established weeds should be eliminated by cultivation prior to treatment.
Do not apply more than 4 pounds per treated acre in any one application.
FILBERTS
Diuron 80DF is recommended for control of certain weeds in filbert orchards
established for at least one year. Apply Diuron 80DF as a directed spray, avoiding
contact on the foliage and fruit with spray or drift. Make an initial treatment of 2.75
pounds per acre in the late fall or early winter after harvest. Repeat annually with
2.75 pounds per acre, or apply 2 pounds in October or November after harvest and
repeat at the same rate in March or April. Allow a minimum of 150 days between
applications. Do not apply more than 4 pounds product per acre per year. Do not
apply when nuts are on the ground. Do not graze livestock in treated orchards. Do
not use on light sandy soils. If trees are planted on hillsides, the elimination of weeds
and ground cover may cause excessive soil erosion. Under these conditions strip
application of Diuron 80DF (at proportionately lower rates) may be made near the
trees or to the tree rows perpendicular to the slope. Apply a maximum of two
applications per year.
GRAPES
Apply only to established vineyards (at least 3 years old) as a band treatment to
grape rows. On soils low in clay or organic matter (1 to 2%), severe plant injury may
result if heavy rainfall or more than one inch of irrigation occurs soon after treatment.
This risk must be assumed by the user. Do not apply more than 5 pounds (4 Ibs.
ai/A) per acre per application. Do not make more than two applications per year.
Maximum application rate per crop cycle is 10 pounds (8 Ibs. ai/A) per acre. When
using this product in a sequential treatment program, allow a minimum of 90 days
between applications.
East of the Rocky Mountains: On soils low in clay or organic matter (1 to 2%), apply
2 to 3 pounds per acre; on soils high in clay or organic matter, apply 3 to 5 pounds
per acre. Apply in the spring just prior to germination and growth of annual weeds.

28
West of the Rocky Mountains: For best results, apply during the winter months
when weeds are less than 2 inches in height or diameter. Rainfall or overhead
sprinkler irrigation sufficient to wet the soil to a depth of 2 inches is necessary to
activate the herbicide. Abnormally heavy rainfall following application just before
spring growth may move the herbicide into the root zone of grapes which could result
in injury. For initial treatment, apply 3 to 4 pounds per acre; subsequent annual
applications of 2 pounds per acre will usually give adequate weed control. Do not
apply to vines with trunks less than T1/£" in diameter as injury may result.
New York and Pennsylvania-Perennial Grass: Use only in established vineyards (at
least 4 years old) for spot control of perennial grasses such as orchardgrass,
quackgrass, and ryegrass. Apply in the spring as a band treatment to ridged soil (2"
and 4" high) under the trellis at the rate of 5 pounds per acre. Band width should not
exceed 30". Do not apply more than once every 4 years. Use only on heavy soils
such as loams, silt loams, or clay loams. Do not use in areas where grape roots are
shallow or exposed because of high bedrock, poor drainage, or erosion as injury to
grapes may result.
MACADAMIA NUTS-Hawaii
Use only under trees established in the orchard for at least 1 year. Apply 2 to 6
pounds per acre immediately after harvest, preferably before weeds emerge; if weeds
have emerged, add 1 pint of an approved non-ionic surfactant per 25 gallons of
spray. Repeat as needed but do not exceed 10 pounds per acre per year.
OUVES-California
Use only under trees established in the grove for at least 1 year. Apply 2 pounds per
acre after grove has been laid-up in final form in late October or November; repeat at
same rate in March or April. Remove weed growth prior to treatment.
PAPAYAS
Use only under trees established in the orchard for at least 1 year. Apply 2.5 to 5
pounds per acre, preferably before weeds emerge; if weeds have emerged, add 1 pint
of an approved non-ionic surfactant per 25 gallons of spray.
PEAS (Austrian Field)
Western Oregon: Diuron 80DF is for selective control of certain weeds in Austrian
field peas. Apply 1.5 to 2 pounds per acre as a broadcast spray with air or ground
equipment as soon as possible after planting but before crop emerges for control of
weeds such as chickweed, shepherdspurse, wild mustard, fiddleneck, lambsquarters,
pigweed and annual bluegrass. Use lower rate on coarse-textured soils and higher
rate on fine-textured soils. Do not use Diuron 80DF on sand, sandy loam, gravelly
soils or exposed subsoils or on soils having less than 1% organic matter as crop
injury may result. Do not replant treated area to another crop within one year of
application. Crop injury may result if severe winter stress, disease or insect damage
to the crop follows application.

r

PEACHES
Where crop is grown under furrow irrigation or under raised-berm flood irrigation
(trees 4" to 6" above waterline), apply only as a band treatment. Do not treat trees
planted in the bottom of irrigation furrows, nor trees grown under flat flood or basin
irrigation, as injury to trees may result. Where complete weed control to harvest is
desired, additional weed control measures may be required during the growing
season.
DIURON 80DF Alone-Use only under trees established in the orchard for at least 3
years. Apply 2 to 2.75 pounds per acre in the early spring before weeds emerge or
during the early seedling stage of weed growth. In California, apply 2 to 3.75
pounds per acre. Do not apply within 3 months of harvest; in the Far West, do not
apply within 8 months of harvest.

PINEAPPLE
Hawaii and Florida
Apply 2 to 6 pounds per acre (Hawaii) or 4 to 8 pounds per acre (Florida) as a
broadcast spray just before or immediately after planting but prior to weed
emergence. Use 2-4 pounds per acre (Hawaii) or 4 pounds per acre (Florida) after
harvesting plant crop or ratoon crop. For plant crop only, a second and third
broadcast or interspace application may be made prior to differentiation at the rate of
2 pounds per acre at intervals of not less than 2 months. Additional applications to
plant crop may be made as needed to interspace only using 2 pounds per acre. Do
not apply more than 3 broadcast sprays (maximum 12 pounds per acre) prior to
differentiation nor more than 16 pounds total per acre per plant crop. Treated areas
may be planted to pineapple or sugarcane 1 year after last application.
Puerto Rico
Apply 3.75 to 6.25 Ibs. per acre as a broadcast spray before or immediately after
planting but prior to weed emergence. Application controls weeds such as pigweed,
crotalaria, morningglory, purslane, crabgrass, foxtail, goosegrass, fall panicum and
sourgrass.
WALNUTS (English)-California, Oregon, Washington
Use only under trees established in the orchard for at least 1 year. As an initial
treatment, apply 2.75 pounds per acre after the orchard has been laid up in final form
(nontillage program) in late fall or early winter; retreat annually with 2 to 2.75 pounds
per acre. Alternatively, apply 2 pounds per acre in October or November and repeat
at same rate in March or April. In California apply 2 to 3.75 pounds per acre.

r(
31
Do not use on sand, loamy sand, gravelly soils or exposed subsoils, nor where
organic matter is less than 1%. Do not graze livestock in treated orchards and
groves.
Apply a maximum of two applications per year. Do not apply more than 4 pounds per
acre per year. In California do not apply more than 3.75 pounds per acre per year.
Minimum retreatment interval is 150 days.
TREE PLANTINGS
Colorado, Montana, Nebraska, North Dakota, South Dakota, Wyoming: Use only
under established plantings (1 year or older) of American elm, caragana, cottonwood,
Douglas fir, green ash, honeysuckle, Ponderosa pine, red cedar, Russian olive and
Siberian elm. Use 2Vz to 5 pounds per acre; apply as a band 4 feet wide in the tree
row (2 feet on each side of row). For example, 1 oz. DIURON 80DF (4 level
tablespoonfuls) treats 135 feet of tree row (2 feet on each side of row) at the rate of
5 pounds per acre. Apply as a directed spray in early spring before weeds emerge
and before trees leaf out. Do not apply to foliage of trees, nor under trees growing in
low areas as injury to the trees may result.
Idaho, Oregon, Washington: Diuron 80DF is for control of weeds to aid in the
establishment of hybrid poplar plantings. Apply 1 to 3 pounds per acre depending
upon soil texture and organic matter content. Use 1 to 2 pounds per acre on coarse-
textured soils and 2 to 3 pounds per acre on medium to fine textured soils. Do not
use on gravelly soils or on any soil having less than 0.5% organic matter as injury to
trees may result. Injury may result from applications to poplar plantings grown on
sandy soil with low organic matter with sprinkler irrigation. When applied in a band,
the application rate will be in proportion to the area banded on a per acre basis.
Apply in late winter or early spring as a uniform broadcast spray before or after
planting but prior to bud swell, or as a directed spray after bud swell. Apply before
weeds emerge or after emergence while weeds are small. Some rainfall or water is
necessary to move Diuron 80DF into the weed root zone before weeds become well
established. If weeds are present at time of treatment, add a surfactant at 1 to 2
quarts per 100 gallons of spray solution.
Preplant: Take precautions to prevent treated soil (usually top 1 inch) from coming
into contact with roots of trees during the planting process as injury may result.
Postplant (broadcast): It is best to wait until rain or irrigation has settled the soil
around the newly planted trees before applying Diuron 80DF. If trees are dormant, a
broadcast application can be made.
Postplant (directed): If buds have started to swell, use a directed spray pattern that
prevents Diuron 80DF from contact with trees as injury may result. During the
growing season (from bud swell to leaf drop) Diuron 80DF may be applied (alone or
with tank mix) between tree rows in a shielded and directed sprays.
Diuron 80DF can be tank mixed with a labeled glyphosate herbicide preplant and as a
directed spray to broaden the spectrum of weeds controlled and improve

r
32
postemergence activity. Use 1 to 3 pounds per acre Diuron 80DF plus glyphosate
herbicide (according to label recommendations) depending upon soil type and weeds
to be controlled. Note: There are several formulations of glyphosate herbicide.
Check the glyphosate herbicide label to verify that the intended use as a preplant or
postdirected spray on hybrid poplar plantations is allowed. Avoid contact of
glyphosate herbicide with foliage, green stems, trees or other desirable vegetation
because severe damage or destruction may result.
NON-CROP WEED CONTROL
DIURON 80DF is an effective herbicide for the control of many annual and perennial
grasses and herbaceous weeds on non-cropland areas where bare ground is desired.
The degree of control and duration of effect will vary with the amount of chemical
applied, soil texture, rainfall and other conditions.
DIURON 80DF may be used as a preemergence treatment at any time of the year
except when ground is frozen, provided adequate moisture is supplied by rainfall or
artificial means to activate the herbicide. Best results are obtained if application is
made to the soil shortly before weed growth begins. If dense growth is present,
remove tops and spray the ground.
Increased contact activity on established weeds may be obtained by the addition of
an approved non-ionic surfactant at the rate of 2 quarts per 100 gallons of spray
mixture. Apply as a drenching spray to actively growing weeds during warm weather
when daily temperature will exceed 70° F.
Except for small areas, use a fixed-boom power sprayer properly calibrated to insure a
constant rate of application. Mix proper amount of DIURON 80DF into volume of
water necessary to obtain uniform coverage. If a surfactant is used, dilute with 10
parts of water and add the surfactant as the last ingredient to nearly full tank.
Material must be kept in suspension at all times. Agitate by mechanical or hydraulic
means in the spray tank; if bypass or return line is used, it should terminate at
bottom of tank to minimize foaming. Openings in screens should be equal to or
larger than 50 mesh.
NOTE: DIURON 80DF may be applied by either ground application equipment or by
air application equipment (helicopter only) for the control of various weeds and
grasses in rights-of-way sites. When making aerial applications, apply in sufficient
water volume to ensure thorough coverage to the site to be treated; generally 5 to15
gallons of water per acre are sufficient.
General Weed Control: To control most weeds for an extended period of time on
non-cropland such as airports, utility, highway, pipeline and railroad rights-of-way,
petroleum tank farms, lumberyards, storage areas, industrial plant sites, and around
farm buildings, apply 5 to 15 pounds per acre to control most annual broadleaves, 5
to 8 pounds per acre to control most annual grasses, and 8 to 15 pounds per acre to
control guineagrass, maidencane, and pangolagrass. In low rainfall areas, DIURON
80DF may not provide satisfactory control of deep-rooted perennial weeds.

Tr

33
Irrigation and Drainage Ditches: Apply 5 to 15 pounds per acre to control most
annual weeds. Apply only when water is not in the ditch. For irrigation ditches,
apply during the non-crop season, and when ditch is not in use. To minimize
movement of DIURON 80DF with irrigation water (to avoid possible crop injury), it is
essential that the herbicide be fixed in the soil by moisture. Apply before expected
seasonal rainfall (if possible when soil in the ditch is still moist). Following treatment,
if rainfall has not totaled at least 4 inches, fill ditch with water and allow to stand for
72 hours; drain off any waste water remaining before using the ditch. Do not treat
any ditch into which roots of trees or other desirable plants may extend as injury may
result.
Dry Application: Diuron 80DF may be applied dry for control of the listed weeds on
non-crop sites. Apply Diuron 80DF granules using dry application (ground) equipment
to distribute the granules uniformly to the target area.
Note: The maximum application rate in areas of high rainfall or dense vegetation is 15
Ibs/A (12 Ibs. ai/A). The maximum application rate in all other areas is 10 Ibs./A (8
Ibs. ai/A). Do not apply more than 2 applications per year. The minimum retreatment
interval is 90 days.
