USE INFORMATION 
Use of Diuron in certain portions of California, Oregon, and Washington is subject to the January 22, 2004 Order 
for injunctive relief in Washington Toxics Coalition et al vs E PA, C01-132C (W.D. WA.). For information, please 
refer to www.epa.gov/espp/wtc/.
This product is to be mixed with water and applied as a spray f or selective control of weeds in certain crops and 
for non-selective weed control on non-cropland areas. It is non -corrosive to equipment, nonflammable and non-
volatile.
This product may be applied to soil prior to emergence of weeds to control susceptible weed seedlings for an 
extended period of time; the degree of control and duration of effect will vary with the amount of chemical applied, 
soil texture, rainfall and other conditions. Soils high in clay or organic matter require higher dosages than soils low 
in clay or organic matter to obtain equivalent herbicide performance. Moisture is required to activate the chemical; 
best results occur if rainfall (or sprinkler irrigation) occurs within 2 weeks of application. 
This product, applied pre-emergence, before emergence of crop a nd weeds, is an effective procedure because 
susceptible weeds are controlled in an early, vulnerable seedli ng stage before they compete with the crop. With 
favorable moisture conditions, this product continues to control weeds for some time as the crop becomes better 
able to compete. Should weed seedlings begin to break through t he pre-emergence treatment in significant 
numbers, secondary weed control procedures should be implemente d; these include cultivation and post-
emergence herbicide application.

Page3of23

This product may also be used to control emerged weeds. Results vary with rate applied and environmental 
conditions; best results are obtained on succulent weeds growin g under conditions of high humidity and 
temperatures of 70°F or higher. Addition of a non-ionic surfact ant to the spray (where recommended) increases 
contact effects of this product. 
This product may be used as a directed post-emergence applicati on where spray nozzles are adjusted so that 
weeds are sprayed, but the crop is not on the following crops: Artichokes, Corn (field), Cotton, Sorghum (grain), 
Sugarcane and established plantings of Apples, Bananas, Blueber ries, Caneberries, Citrus, Gooseberries, 
Filberts, Grapes, Macadamia nuts, Olives, Papayas, Peaches, Pears, Pecans, Plantains, Walnuts and certain Tree 
plantings. 
Under specified conditions (see “DIRECTIONS FOR USE”), this product without surfactant may be applied over 
the top of Alfalfa (established, dormant or semi-dormant), Aspa ragus (established), Birdsfoot trefoil (established, 
dormant), Grass seed crops (established), Oats, Pineapple, Plum osus fern (established, mowed), Red clover 
(established, dormant), Sugarcane and Wheat. 
Weed species vary in susceptibility to this product and they ma y be more difficult to control when under stress. 
Combinations of this product with other herbicides (as register ed) increase the number of species controlled; 
consult labels of the companion products for this and other information. 
Since the effect of this product varies with soils, uniformity of application and environmental conditions, it is 
suggested that growers limit their first use to small areas. Observe all precautions and limitations on labeling of all 
products used in mixtures. 
IMPORTANT: Injury to or loss of desirable trees or other plants may result from failure to observe the following: 
Do not apply (except as directed for crop use), or drain or flu sh equipment on or near desirable trees or other 
plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into 
contact with their roots. Do not use on home plantings of trees, shrubs or herbaceous plants, nor on lawns, walks, 
driveways, tennis courts or similar areas. Prevent drift of dry powder or spray to desirable plants. Do not 
contaminate any body of water. Do not mix/load or use near wells including abandoned wells, drainage wells and 
sinkholes. Avoid storage of pesticides near well sites. Keep fr om contact with fertilizers, insecticides, fungicides 
and seeds. Calibrate sprayers only with clean water away from w ell site. Do not apply this product through any 
type of irrigation system. Thoroughly clean all traces of this product 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 MANAGEMENT 
GROUP 7 HERBICIDE 
This product is a Group 7 herbicide. Any weed population may contain or develop plants naturally resistant to this 
product and other Group 7 herbicides. 
When herbicides affecting the same biological site of action are used repeatedly over several years to control the 
same weed species in the same field, naturally-occurring resist ant biotypes may survive a correctly applied 
herbicide treatment, propagate, and become dominant in that fie ld. Adequate control of these resistant weed 
biotypes cannot be expected. It may be necessary to retreat the problem area using a product affecting a different 
site of action, if weed control is unsatisfactory. To better ma nage 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/o r appropriate state agricultural extension service 
representative for specific alternative cultural practices or herbicide recommendations available in your area.

Page4of23

INTEGRATED PEST MANAGEMENT 
This product may be used as part of an Integrated Pest Manageme nt (IPM) program that can include biological, 
cultural, and genetic practices aimed at preventing economic pe st damage. IPM principles and practices include 
field scouting or other detection methods, correct target pest identification, population monitoring, and treating 
when target pest populations reach locally determined action thresholds. 
Consult your state cooperative extension service, professional consultants or other qualified authorities to 
determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.
DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product 
in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be 
in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible 
for pesticide regulation. 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protection Standard (WPS), 40 CFR 
Part 170. This standard contains requirements for the protectio n of agricultural workers on farms, forests, 
nurseries, greenhouses and handlers of agricultural pesticides. It contains requirements for training, 
decontamination, notification and emergency assistance. It also contains specific instructions and exceptions 
pertaining to the statements on this label about personal protective equipment (PPE) and restricted entry interval 
(REI). The requirements in this box only apply to uses of this product that are covered by the WPS. 
Do not enter or allow worker entry into treated areas during the REI of 12 hours. 
PPE required for early entry to treated areas that is permitted under the WPS and that involves contact with 
anything that has been treated, such as plants, soil or water i s: Coveralls, chemical-resistant gloves made of 
any waterproof material, and shoes plus socks. 
NON-AGRICULTURAL USE REQUIREMENTS 
The requirements in this box apply to uses of this product that are not within the scope of the Worker Protection 
Standard (WPS) for agricultural pesticides 40 CFR Part 170. The WPS applies when this product is used to 
produce agricultural plants on farms, forests, nurseries or gre enhouses. Do not enter or allow others to enter 
treated areas until sprays have dried. 
Non-crop weed control is not within the scope of the WPS.

SPRAY DRIFT MANAGEMENT 
Requirements for reducing spray drift for Diuron ground and aerial applications: 
Use best practices to avoid drift to all other crops and non-ta rget areas. Do not apply when conditions favor drift 
from target areas. The interaction of many equipment- and weath er-related factors determine the potential for 
spray drift. Avoiding spray drift at the application site is th e responsibility of the applicator. The applicator must 
follow the most restrictive precautions to avoid drift, includi ng those found in this labeling as well as applicable 
state and local regulations and ordinances. A drift control agent may reduce drift, however, it may also decrease 
weed control. 
Make aerial or ground applications only when the wind speed is less than or equal to 10 miles per hour. Do not 
make aerial or ground applications into temperature inversions. Apply with medium or coarser spray (according to 
ASAE standard 572) for standard nozzles. 
Additional requirements for ground applications: 
When applying to crops, apply with nozzle height no more than 2 feet above the ground or crop canopy. When 
applying to non-crop areas, use lowest nozzle height consistent with safety and efficacy. Direct spray into target 
vegetation. 
Additional requirements for aerial applications: 
The spray boom should be mounted on the aircraft so as to minimize drift caused by wing top vortices. The boom 
length must not exceed 76% of the wingspan or 90% of rotor blade diameter. Use upwind swath displacement. 
When applying to crops, do not release spray at a height greater than 6 to 10 feet above the ground or crop canopy. 
When applying to non-crop areas, apply at a minimum safe altitude above the area being treated. 
Do not apply by air if sensitive non-target crops are within 100 feet of the application site. 
APPLICATION DIRECTIONS 
AERIAL APPLICATION: Aerial application is prohibited in all crops EXCEPT for the fo llowing: Alfalfa, Barley 
(Winter), Cotton (pre-plant or pre-emergence only), Grass seed crops (grown in Pacific Northwest only), Rights-
of-way, Sugarcane and Wheat (Winter). Application may be made by aircraft at 5 to 10 gallons of water per acre. 
Avoid overlapping of spray swath and avoid application under conditions where excessive drift may occur. Where 
land is bedded, make application parallel to rows. 
GROUND APPLICATION: Use a boom power sprayer properly calibrated to a constant speed and rate of delivery. 
Openings in screen should be 50-mesh or larger. Continuous agit ation in the spray tank is required to keep the 
material in suspension. Agitate by mechanical or hydraulic mean s. If bypass or return line is used, it should

Page6of23

terminate at the bottom of the tank to minimize foaming. Avoid overlapping and shut off spray booms while starting, 
turning, slowing or stopping, or injury to crop may result. 
PRE-EMERGENCE: Use sufficient spray volume and pressure to uniformly distribut e the spray solution over 
treated soil. Pre-emergence weed control will be reduced on high organic matter soils such as peat or muck.
POST-EMERGENCE: Use sufficient spray volume and pressure for 
thorough coverage of weed foliage. For selective applications and applications near sensitive crops, use low spray 
pressure to keep spray drift to a minimum. This product at labeled rates, controls seedling Annual 
weeds such as Annual morningglor y, Barnyardgrass (Watergrass), Crabgrass, Crowfoot, Goosegrass, Pigweed 
and Purslane. 
Addition of a surfactant to the spray (where recommended) increases contact effects of this product. Best results 
are obtained on succulent weeds growing under conditions of high humidity and temperatures of 70°F or higher. 
SPRAY PREPARATION: Mix proper amount of this product into necessary volume of wate r. Where use of a 
surfactant is recommended, dilute with 10 parts of water and add as last ingredient to a nearly full tank. 
TANK MIXTURES: This product may be tank mixed with other herbicides and/or adjuvants registered for crop or 
non-crop use in this label. Refer to the label of the tank mixt ure partner(s) for any additional use instructions or 
restrictions. Always follow the most restrictive label. 
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 as 
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 crop(s) intended for production. The test crop(s) strip should 
cross the entire field including knolls, low areas and areas wh ere any berms were located. The result of this 
bioassay may require the rotation intervals to be extended. 
RATES: Unless otherwise stated, all rates on this label are expressed as broadcast rates of this product. For band 
treatment, use proportionately less. For example, use one-third of the broadcast rate when treating a 14-inch band 
where row spacing is 42 inches. Where a range of dosages is giv en, use the lower rate on Coarse textured soils 
low in clay or organic matter and the higher rate on Fine textu red 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 from failure to observe the following: U nless otherwise directed, do 
not use on Sand, Loamy sand or Gravelly soils or exposed subsoil, nor on Pecans where organic matter is 
less than 0.5%, nor on Alfalfa, Apples, Artichokes, Barley (Winter), Citrus, Cotton, Grapes, Oats, Olives, Papayas, 
Peaches, Pears, Sorghum, Sugarcane, Walnuts and Winter wheat wh ere organic matter is less than 1%, nor on 
Blueberries, Birdsfoot trefoil, Caneberries, Gooseberries, Macadamia nuts and Peppermint where organic matter 
is less than 2%. 
USES 
FIELD CROPS (See Soil Limitations) 
A good seedbed must be prepared before pre-emergence use of thi s product, 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 of this product 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 Alfalfa/Grass mixtures; do 
not apply to Alfalfa under stress from disease, insect damage, shallow root penetration (such as on shallow hard 
pans), or alkali spots, nor to flooded fields as crop injury ma y result. Do not spray on snow-covered or frozen 
ground. 
Maximum application rate per crop cycle is 2.4 pounds active ingredient (3 pounds of this product) per acre. Make 
only one application per year. 
ID, OR, WA: Use 1.5 to 3 pounds per acre for control of annual weeds in Fal l after Alfalfa becomes dormant, but 
not later than mid-December.

Page7of23

CA (Dormant and Semi-Dormant Varieties): Use 1.5 to 3 pounds per acre 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 resul ts, apply before weeds have emerged or become 
established (2 inches in height or diameter). Control of establ ished weeds is improved by applying this product 
with a suitable contact herbicide registered for such use. Suff icient rainfall for soil activation of this product is 
unlikely in CA 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. 
AZ, NV: Use 1.5 to 3 pounds per acre in Fall after Alfalfa becomes dormant but no later than January. 
Eastern CO, KS: For control of Tansymustard, apply 1 pound per acre shortly after emergence of Mustard in the 
Fall or Winter; use 2 pounds per acre if weeds are 2 inches to 4 inches in height. 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 (1.5 to 2 pounds per acre 
East of Appalachian Mountains) in March or early April, but before Spring growth begins. 
Artichokes
CA: 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 betwee n the rows and at the base of Artichoke plants, 
keeping contact with crop plants at a minimum. Aerial application is prohibited. 
Asparagus
Apply as a band or broadcast treatment. Do not apply to young p lants during the first growing season (except as 
noted below), nor to newlyseeded Asparagus, nor on plants with exposed roots, as severe injury may result. Pre-
emergence weed control will be reduced on soils with greater th an 5% organic matter. Aerial application is 
prohibited. 
Established Plantings: On light 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 t he last cultivation); a second application may be 
made immediately following completion of harvest, provided rainfall is expected. 
When two applications are used in one season, do not exceed 3 pounds per acre per application. In WA (irrigated 
crop), apply a single treatment of 4 pounds per acre. If treatm ent is delayed until late Winter or early Spring, 
incorporation of the chemical in the top 1 to 2 inches of soil may substitute for lack of rain to activate the herbicide. 
Newly Planted Crowns—CA (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 Clay loam s and the higher rate on Peat soils. Do not use on 
soils containing less than 2% organic matter. Soils must be settled by rainfall or irrigation prior to treatment. Do not 
treat crowns planted to a depth of less than 2 inches. 
Barley, Winter 
Western OR and Western WA: For drill-planted Barley, 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 thelast application as injury to subsequent crops may result. 
Bermudagrass Pastures (Newly-Sprigged) 
Apply 1 to 3 pounds after planting and before emergence of Berm udagrass or weeds. Alternatively, for control of 
emerged annual weeds up to 4 inches in height, apply 0.5 to 1 pound per acre; add a surfactant per 25 gallons of 
spray. If Bermudagrass has emerged at time of treatment, temporary burn of exposed plant parts may occur. 
Plant sprigs (stolons) 2 inches deep in a well-prepared seedbed; do not treat areas where sprigs are planted less 
than 2 inches deep, as crop injury may result. Do not graze or feed foliage from treated areas to livestock within 
70 days after application. Aerial application is prohibited.

Page8of23

Birdsfoot Trefoil (Lotus) 
Western OR: 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 Decem ber 15). Do not 
replant treated areas to any crop within 1 year after last appl ication, as injury to subsequent crops may result. 
Aerial application is prohibited. 
Corn (Field) 
Aerial application is prohibited. 
Post-emergence: Make a single application of 0.75 pound per acre in combination with non-pressure nitrogen 
solution. If nitrogen solution is not used, apply 1 pound per acre. Add a surfactant. Apply as a directed spray when 
Corn is at least 20 inches tall and weeds are no taller than 3 inches. DO NOT APPLY OVER TOP OF CORN. Do 
not replant to any crop within 1 year after last application as injury to subsequent crops may result, except Corn, 
Cotton and Grain sorghum may be planted the Spring following treatment. 
Pre-emergence—AR, LA, MS and TN: Make a single application of 0.67 to 1 pound per acre as a broa dcast or 
band treatment after planting, but before Corn emerges. Plant Corn at least 1.5 inches deep. Do not replant treated 
areas to crops other than Corn or Cotton within 4 months follow ing band treatment and 6 months following 
broadcast treatment, as crop injury may result. 
Cotton
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. Seedling disease may weaken plants and increase the pos sibility of injury from the use of Trifluralin EC 
followed by this product. These treatments should be used only in conjunction with a standard fungicide seed 
treatment plus a good supplemental soil fungicide program such as Captan-PCNB mixture. 
DO NOT SPRAY OVER THE TOP OF COTTON PLANTS. 
Do not use this product in pre-plant or pre-emergence applicati ons where soil-applied organophosphate 
insecticides are used due to potential for severe cotton injury and possible stand loss. Do not allow 
livestock to graze treated Cotton. The maximum application rate per crop cycle is as follows: 
Type of Soil Pounds of Diuron a.i. per Acre Pounds of This Prod uct per Acre 
Coarse 0.8 1 
Medium 1.5 1.875 
Fine 2.2 2.75 
Do not make more than 3 applications per year. 
NOTE: When using this product in a sequential treatment program, allo w a minimum of 21 days between 
applications. 
Pre-plant—AZ and CA: Use this product alone or apply as a separate operation followi ng pre-plant broadcast 
treatment with Trifluralin EC (incorporated according to direct ions on product label). Apply this product 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 this product. Treated soil is returned to the bed after planting 
when irrigation furrows are reformed after Cotton has emerged. If more than two furrowing-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:

Pre-Plant (Except AZ and CA): This product 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 cott on 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 this product 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 applicatio n for a given soil is applied pre-plant, subsequent 
preemergence applications of this product may be made. However, the total combined application rate for this 
product applied pre-plant and pre-emergence may not exceed the maximum suggested use rate for either 
application method.

Pre-emergence application of herbicides with a similar mode of action to that of Diuron following pre-plant 
application of this product may result in cotton injury. When p re-plant applications of this product are followed by 
pre-emergence applications of herbicides with a similar mode of action, e.g., Meturon®, Cotoran® or other products 
containing fluometuron, the product containing fluometuron should be used at the minimum rate of application for 
the soil under consideration in order to reduce potential for c rop injury. This is most critical where applications of 
this product are made less than 30 days pre-plant, on Coarse te xtured soils, and on soils low in organic matter. 
The risk of injury from pre-plant applications of this product is reduced where substantial rainfall 
(more than 0.5 inches) occurs between application and planting. 
Read and follow any additional precautions on this label when u sing this product for pre-plant weed control in 
Cotton. 
Pre-Plant Tank Mixes: When emerged weeds taller than 2 inches or weeds not listed on this label are present, 
this product may be tankmixed with other products labeled for p re-plant applications in Cotton, including Boa™, 
Glyphosate Original, Gramoxone ® Extra, Imitator ® Plus, Roundup ® Ultra, and Touchdown ®. The addition of dry 
spray grade ammonium sulfate at the rate of 2% w/w (17 pounds p er 100 gallons finished spray solution) is 
suggested to enhance performance of this product plus glyphosate tank mixes. 
Replanting: Only Cotton and Corn may be planted within 6 months of pre-plan t applications of this product. To 
avoid crop injury following replanting, avoid disturbing the original bed. 
Pre-emergence—Except AZ, CA: Use this product alone or apply as a separate operation followi ng pre-plant 
treatment with Trifluralin EC. Apply this product after plantin g, but before Cotton emerges. Do not treat Cotton in 
deep furrows as crop injury may result. Use only where Cotton i s planted on flat or raised seedbeds. Shallow 
incorporation (no deeper than 0.25 inch) 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 post-emergence treatments. If moisture is insufficient to activate this product or if soil 
becomes crusted before crop emerges, a shallow rotary hoeing (no deeper than 0.25 inch) should be made before 
weeds become established. 
This product 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, addit ional product may be applied preemergence. 
However, the total amount of this product applied preplant and preemergence must not exceed the maximum 
suggested use rate for either preplant or preemergence applications.

Post-emergence: Apply only as a directed spray to cover weed foliage; adjust no zzles to minimize contact of 
Cotton leaves with spray or drift or crop injury may result. Ap plications may also be made in hooded/shielded 
sprayers. 
Early Season: Apply when Cotton is at least 6 inches tall and when weeds are actively growing and do not exceed 
2 inches in height. Apply as a band or broadcast treatment at t he following rates. Two applications may be made 
if needed.

For control of seedling Perennial grasses such as Johnsongrass, in directed sprays and partial control of Nutsedge 
or when weed growth is under drought stress or over 2 inches tall add 1.65 to 2 pounds active MSMA to the above 
spray mixture. If MSMA is used, do not apply after first bloom. 
For enhanced weed control in hooded/shielded sprayer applicatio ns, add MSMA as suggested above; or Boa, 
Gramoxone Extra, Glyphosate Original, Imitator Plus, Roundup Ultra, or Touchdown according to label directions. 
Consult product labels for specific directions and precautions for hooded sprayer applications. 
Late Season (Lay-By): Apply 1 to 1.5 pounds per acre (1 to 2 pounds per acre in AZ an d CA) when Cotton is at 
least 12 inches tall (at least 20 inches tall for Pima S-2). Fo r control of germinating weed seedlings, apply to soil 
beneath Cotton plants and between rows immediately after last c ultivation. In irrigated Cotton, best weed control 
is obtained if the field is irrigated within 3 to 4 days after application, to thoroughly wet the surface of the ground 
over the row to carry the herbicide into the root zone of germi nating weeds. Alternatively, for control of emerged 
Annual weeds (up to 4 inches in height) at lay-by time, make a single application in combination with a surfactant 
or use 0.5 to 0.75 pound of this product (plus surfactant) per acre and repeat later, if needed. 
Replanting: If initial seeding fails to produce a stand, Cotton may be replanted in soil treated pre-emergence with 
this product alone or following pre-plant application of Triflu ralin EC. Wherever possible, avoid disturbing original 
bed. If necessary to rework soil before replanting, use shallow cultivation such as discing; do not relist nor move 
soil into the original drill area. Plant seed at least 1 inch d eep. Do not retreat field with a second pre-plant or pre-
emergence application during the same crop year, as injury to the crop may result.

For subsequent crops in fields where Trifluralin EC is used, follow instructions on Trifluralin EC product label(s).

Grass Seed Crops (Perennial Except Where Specifically Indicated) 
Except as noted, apply only to established plantings at least 1 year old. 
Do not apply more than 2.4 lbs. of active ingredient (3 lbs. of this product) per acre per year. Do not apply more 
than once per year. Aerial application is limited to the Pacific Northwest only. 
Do not replant treated areas to any crop within 2 years of last application, as injury to next crop may occur. 
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, env ironmental stress, insects, disease or damage from 
other herbicides. 
CO, KS, NM and OK: On Sand bluestem, Side-oats grama and Switch-grass, 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 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. 
Eastern OR, Eastern WA: On Perennial bluegrass and Fescue apply 1 to 3 pounds per acre as broadcast in 
enough diluent to get even distribution. Apply in Spring before rapid growth of the crop begins and when the 
Windgrass is still small (1- to 4- leaf). DO NOT use on Coarse (sand) textured soils. 
Western OR, Western WA: 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. 
WA: Apply in the Fall to Perennial ryegrass to control weeds and seedling grasses such as annual bluegrass and 
volunteer 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 in 
minimum of 25 gallons of water per acre by ground and minimum of 5 gallons of water by air, 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). Establis hed weeds beyond the 2- to 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. 
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 app lications generally will occur between October 
1 and January 15. This product 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 post-emergence 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 move ment into the intended crop row area is 
recommended. 
Fine Fescue Grass Seed Crops (including Chewings, Creeping red and Hard fescue types): For the 
suppression of Rattail fescue, apply at 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: This product is for use on healthy, vigorous stands of Fine fes cue. This 
product 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 a pplication. Apply in Fall before Grass weeds are 
beyond the 1- to 2-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 0.5 to 1 inch of rainfall or sprinkler irrigation
 is needed to move this product in 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 this product 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 and Sequential Treatments: This product can be applied either alone or in a program involving tank 
mixes and/or sequential treatments with other herbicides and ad juvants. When using a tank mix with other 
herbicides, use 1 to 1.5 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 certain tank mixes for the first time, limit use 
to a small area to determine safety before treating large areas. 
New Plantings (ID, OR, WA): For use in newly planted Bentgrass, Chewing fescue, Kentucky bl uegrass, 
Perennial ryegrass, Orchardgrass and Tall fescue. During planti ng operation, spray a suitable brand of activated 
charcoal as a 1-inch band on soil surface at a rate of 300 poun ds per acre (broadcast basis; equivalent to 15 
pounds per acre of crop when row spacing is 20 inches). Mount nozzles to apply directly over seed rows to prevent 
crop injury. Follow with this product as a single broadcast spr ay at a rate of 2.5 to 3 pounds per acre. Apply as 
soon as possible after planting, but before crops or weeds emer ge 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. 
Perennial Ryegrass, Tall Fescue, Kentucky Bluegrass and Fine Fescue (Grown For Seed) (OR 
Only) 
For control of certain Broadleaf weeds and Annual grasses, appl y this product only to well established vigorous 
stands of grasses as directed below. Use sufficient water, a minimum of 26 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 be yond 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 accumul ated 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 us ing this product 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. Do not apply this product 
through any type of irrigation system. 
Perennial Ryegrass (Established): 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 the product 
label.

per acre as a broadcast spray with air or ground equipment as s oon 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 this product on Sand, Sandy loam, Gravelly soils or exp osed 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 inse ct damage to the crop follows application. Aerial 
application is prohibited. 
Peppermint (Pacific Northwest) 
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 s now covered or frozen ground as injury to the 
crop or poor weed control may result. Do not apply to Sand, Loa my sand, Gravelly soils or exposed subsoils. Do 
not apply to soils that have a high salt content and/or high wa ter 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. Aerial 
application is prohibited.

0.75 to 1 lb. 1 to 2 lbs. 2 to 3 lbs. 

Application Timing: Apply this product to established stands of Mint during the lat e 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 the time of application, the use of a s urfactant at 0.25% v/v or crop oil concentrate at 1% 
v/v may be used to increase the performance of this product post-emergence to weeds. 
Tank Mixes and Sequential Treatments: This product can be applied either alone or in a program involving tank 
mixes and/or sequential treatments with other herbicides and ad juvants, providing this product is not applied to 
actively growing Mint plants. 
When using a tank mix with other herbicides, use the lower end of the rate range of this product 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 OR) 
Make a single application of 2 pounds per acre on established R ed clover stands (at least 9 months). Apply this 
product 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. 
Aerial application is prohibited. 
Treatment will control annual weeds such as Bluegrass, Chickwee d, Hawksbeard, Rattail fescue, Ryegrass and 
Velvetgrass. 
Sorghum—Grain (Southwestern States) 
Apply 0.25 to 0.5 pound per acre. Add a surfactant. Apply as a directed post-emergence broadcast or band spray 
after Sorghum is 15 inches tall to control weeds 2 to 4 inches in height. DO NOT SPRAY OVER 
TOP OF SORGHUM. Use the lower rate on Broadleaved weeds up to 2 inches tall; use the higher rate on grasses 
up to 2 inches and Broadleaved weeds up to 4 inches 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.

Page14of23

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. Aerial application is prohibited. 
Sugarcane
To prevent possible crop injury on new cane varieties, toleranc e to this product should be determined 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 and stunting of the crop may re sult 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 and stunting, use directed post-emergence sprays. 
This product may be applied as a directed spray (including hood ed and shielded spray) in combination with Boa 
and other formulations of paraquat. Consult the label of the ta nk-mix partner for rates and timings of application, 
restrictions and precautions. 
FL — Pre-emergence: 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). 
FL — Post-emergence: Make 1 or 2 applications of 2 pounds per acre, as needed, by di rected spray inter-row. 
Alternatively, for Panicum control, make up to 3 applications of 0.5 to 1 pound per acre plus surfactant as a directed 
spray after cane has emerged, but before Panicum exceeds 2 inch es in height. Adjust nozzles to spray beneath 
cane plants and between rows to cover weed foliage and to minimize contact of cane leaves with spray or drift. Do 
not apply more than 6 pounds total per acre between planting (or ratooning) and harvest. 
HI: 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 po unds 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 and apply as a directed 
spray. Do not apply more than 3 treatments nor more than 12 pou nds per acre in Hawaii between planting (or 
ratooning) and harvest. Treated areas may be replanted to Sugarcane or Pineapple 1 year after application. 
Puerto Rico: Apply 4 to 8 pounds per 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 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 and apply as a directed spray. 
DO NOT SPRAY OVER TOP OF CANE. 
Do not apply more than 3 treatments, nor more than 10 pounds pe r acre between planting (or ratooning) and 
harvest. Treated areas may be planted to Pineapple or Sugarcane one year after last application. 
LA, TX: Apply 3 to 3.75 pounds per acre. This product may be applied as a broadcast spray after planting and 
following the harvesting of Sugarcane. This product may also be applied broadcast in late Winter. Application is 
best when made prior to weed emergence. 
Apply this product as a post-directed spray immediately after the last cultivation. Direct the spray application to the 
base (no more than one-third of the plant height) of the Sugarc ane plants. When small weeds (3 inches or less) 
are present at application, add surfactant at 0.25% v/v or crop oil concentrate at 1% v/v to the spray mix. 
Use Precautions: Temporary leaf yellowing may occur following application. Do not apply more than 7.5 pounds 
per acre broadcast per year. For band application, reduce the a bove broadcast rates proportionately to the width 
of the band using the following formula: 
Band width in inches x Broadcast = Band Rate 
Row width in inches Rate Per Acre 
Wheat, Winter 
Crop injury may result where severe Winter stress, disease or insect damage follows application. Winter-sensitive 
varieties may be less tolerant to this product than Winter-hard y varieties. Crop injury may also result from failure 
to observe the following: Do not use on Sand or Loamy sand soil s, nor on Gravelly or Sand 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 inch deep; do not treat Wheat 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. Unless otherwise specified, do not use 
with surfactants or nitrogen solutions.

Page15of23

Do not replant treated areas to any other crop within 1 year af ter last treatment (except as noted), as injury to 
subsequent crops may result. 
ID, OR and WA (East of Cascade Range): I n areas where average annual 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 inches 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 usual ly give good results provided weed growth is less 
than 4 inches tall. Application later than May 1 may give poor results. 
Alternatively, make a single application of 0.5 to 1 pound of this product plus 0.25 pound bromoxynil per acre as a 
tank mixture, either in the Fall after Wheat has emerged, but b efore soil freezes or in the Spring as soon as soil 
thaws; apply before weeds are 2 inches tall or across. 
In areas where average annual rainfall is 10 to 16 inches, following Fall planting, 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 inches tall. Application later than March 1 may give poor results. 
Note: If 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 whe at. Spring wheat should not be planted before 
April 1 and only after deep discing and plowing to a depth of 4 to 6 inches prior to planting. Do not re-treat field 
with a second application during the same crop year, as injury to the crop may result. 
OR and WA—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 inches tall. 
Alternatively, apply a tank mixture of this product plus bromox ynil as detailed above for “EAST OF CASCADE 
RANGE”. 
Other Areas of OR and WA: Make a single application in the Spring as soon as Wheat (Fall- planted) starts to 
grow and before weeds are 2 inches tall. Application later than May 1 may give poor results. 
Central Plains and Midwest: Use 1 to 2 pounds per acre. 
KS, OK and TX: 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.

Grapes
Apply only to established vineyards (at least 3 years old) as a band treatment. On soils low in clay or organic 
matter (1 to 2%), severe plant injury may result if heavy rainf all or more than one inch of irrigation occurs soon 
after treatment. This risk must be assumed by the user. Do not apply more than 4 lbs. a.i. (5 pounds of this product) 
per acre as a single application. Do not apply more than 8 lbs. a.i. (10 pounds of this product) per acre per year. 
Apply a maximum of 2 applications per year. When using this product in a sequential treatment program, minimum 
retreatment interval is 90 days. 
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 6 pounds per acre. Apply in the Spring just prior to 
germination of annual weeds. 
West of the Rocky Mountains: Apply during the Winter months when weeds are less than 2 inche s in height or 
diameter for best results. 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 1.5 inches in diameter, 
as injury may result. 
NY and PA—Grasses: 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 to 4 inches high) under the trellis at the rate of 8 to 10 pounds per acre. Band width should not exceed 
30 inches. 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 Grapevines may result. 
Macadamia Nuts 
HI: Use only under trees established in the orchard for at least 1 year. Apply 2 to 6 pounds per acre immediately

Do not graze livestock in treated orchards and groves. 
ORNAMENTAL CROPS (See Soil Limitations) 
Aerial application is prohibited. 
Ornamental Bulb Crops (Bulbous Iris, Narcissus [Daffodils]) 
Western WA: Make a single application of 4 pounds per acre. Apply after planting, but no later than 4 weeks prior 
to bulb emergence (usually late September or October). Do not r eplant treated areas to any crop within 1 year 
after last application, as injury to subsequent crops may result. 
Plumosus Fern 
FL: Hand weed and mow fern; then make a single application of 3 pou nds per acre within 3 to 5 days. Do not 
cultivate or disturb soil after application, as crop injury may result. Treat only established stands at least 1 year 
old.
TREE PLANTINGS 
CO, MT, ND, NE, SD, WY: Use only under established plantings (1 year or older) of Ameri can elm, Caragana, 
Cottonwood, Douglas fir, Green ash, Honeysuckle, Ponderosa pine , Red cedar, Russian olive and Siberian elm. 
Use 2.5 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 ounce of this product (4 level tablespoons) 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. 
Hybrid Poplar (ID, OR, WA Only): For control of weeds to aid in the establishment of Hybrid popl ar plantings, 
apply 1 to 3 pounds per acre depending upon silt 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 t o Fine textured soils. Do not use on Gravelly 
soils or on any soil having less than 0.5% organic matter, as i njury 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 this product 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. 
Pre-plant: If application is made prior to planting, 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. 
Post-plant (Broadcast): If application is made after planting, it is best to wait until rain or irrigation has settled the 
soil around the newly planted trees before applying this product. If trees are dormant, a broadcast application can 
be made.

Page21of23

Post-plant (Directed): If buds have started to swell, use a directed spray pattern tha t prevents this product from 
having contact with trees, as injury may result. During the growing season (from bud swell to leaf drop), this product 
may be applied (alone or with tank mix) between tree rows with a shielded and directed spray. 
This product can be tank-mixed with a glyphosate herbicide (Roundup Pro Herbicide, Roundup Original Herbicide 
or Glyphosate Original Herbicide) pre-plant and as a directed spray to broaden the spectrum 
of weeds controlled and improve post-emergence activity. Use 1 to 3 pounds of this product plus glyphosate 
herbicide (according to label directions) depending upon soil t ype 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 post-directed 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 
This product is an effective herbicide for the control of many weeds. The degree of control and duration of effect 
will vary with the amount of chemical applied, soil texture, rainfall and other conditions. This product may be used 
as a pre-emergence treatment at any time of year, except when g round is frozen, provided adequate moisture is 
supplied by rainfall or artificial means to activate the herbicide. Best results are obtained if applications to the soil 
are made shortly before weed growth begins. If dense growth is present, remove tops and 
spray the ground. Increased contact activity on established wee ds may be obtained using a surfactant. Apply as 
a drenching spray to actively growing weeds during warm weather when daily temperature will exceed 70°F. 
Use a fixed-boom power sprayer properly calibrated to ensure a constant rate of application. Mix proper amount 
of this product into volume of water necessary to obtain unifor m coverage. If surfactant is used, dilute with ten 
parts of water and add as last ingredient to a nearly full tank. This product 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 
the bottom of the tank to minimize foaming. Use 50-mesh screen or larger. 
Do not exceed 15 pounds of this product per acre in areas of hi gh rainfall (more than 40 inches/year) or dense 
vegetation (more than 90% weed ground cover). In other areas, do not apply more than 10 lbs. of this product per 
acre. Do not make more than 2 applications per year. If this pr oduct is used in a sequential application program, 
minimum retreatment interval is 90 days. Aerial application is prohibited, except for rights-of-way. 
General Weed Control: This product is used for general weed control in non-cropland s uch as utility, highway, 
pipeline and railroad rights-of-way, petroleum tank farms, lumb eryards, storage areas, airports, sewage disposal 
areas, fence rows, barrier strips, industrial plant sites, arou nd farm buildings, farm yards, and uncultivated
