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 to determine the 
potential for spray drift. The applicator and the grower 
are responsible for considering all these factors when 
making decisions. The following drift management 
requirements must be followed 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. 
1. The distance of the outer most nozzles on the 
boom must not exceed 0/. the length of the 
wingspan or rotor. 
2. 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 droplet 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). 
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-Do not exceed the nozzle 
manufacturer's recommended pressures. For 
many nozzle types, lower pressure produces 
larger droplets. 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 parallel to the airstream 
produces larger droplets than other orientations 
and is the recommended practice. Significant 
deflection from the horizontal will reduce droplet 
size and increase drift potential. 
• Nozzle type- Use a 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 
steam nozzles oriented straight back produce the 
largest droplets and the lowest drift. 
• Boom Length - For some use patterns, reducing the 
effective boom length to less than 3/4 of the 
wingspan or rotor length may further reduce drift 
without reducing swath width. 
• Application - 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 cross-wind, the swath 
will be displaced downwind. 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 
Jf/r!J 
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 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 
Application 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 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, the movement of smoke 
from a ground source or an aircraft smoke generator can 
also identify inversions. Smoke that layers and moves 
laterally in a concentrated cloud (under low wind 
conditions) indicates an inversion, while smoke that 
moves upwards 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). 
GENERAL INFORMATION 
HELENA BRAND DIURON 80WP WEED KILLER is a 
wettable powder to be mixed in water and applied as a 
spray for control of weeds. It is non-corrosive to 
equipment, non-flammable and non-volatile. 
HELENA BRAND DIURON 80WP may be applied to the 
soil prior to emergence of weeds to control susceptible 
weed seedlings for an extended period depending on 
dosage rate used.

Results vary with soil type. Heavy soils (high organic 
matter) require higher dosage rates than lighter soils (low 
in organic matter) to obtain equivalent herbicidal 
performance. Best results occurif rainfall (or irrigation) 
occurs with two weeks of application. 
HELENA BRAND DIURON 80WP also may be used to 
control emerged seeding annual weeds by including a 
surfactant in the spray mixture. Best results are obtained 
on succulent weeds growing under high humidity and 
temperatures of 70
0 
F or higher. 
Since the effect of HELENA BRAND DIURON 80WP 
varies with soils, uniformity of application and 
environmental conditions, it is suggested that growers 
limit their first use to small areas; this is especially 
important where the operator is not completely familiar 
with requirements for precise application, since over 
dosage can result in injury to crops. 
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 recommended for crop use), or drain or flush 
equipment on or near desirable trees or other plants, or 
on areas where their rbots may extend, or in locations, 
where the chemical may be washed or moved into 
contact with their roots. Do not use on lawns, walks, 
driveways, tennis courts, or similar areas. Prevent drifts 
of dry powder or spray to desirable plants. Do not 
contaminate domestic water. Keep form contact with 
fertilizer, insecticides, fungicides, and seeds. [SEE SOIL 
LIMITATIONS]. 
Thoroughly clean all traces of HELENA BRAND DIURON 
80WP from application equipment immediately after use. 
Flush tank, pump, hose, and boom with several changes 
of water after removing nozzle tips and screens (clean 
these parts separately). 
DIRECTIONS 
Before spraying, calibrate equipment to determine 
quantity of water necessary to uniformly cover area to be 
. treated. Weigh proper amount of HELENA BRAND 
DIURON 80WP and mix into necessary volume of water. 
Material must be kept in suspension at all times by 
continuous agitation. Except for small areas, use fixed 
boom power sprayers properly calibrated to insure a 
constant rate of application. Opening in screens should 
be equal to or larger than 50 mesh. Agitate by 
mechanical or hydraulic means in the spray tank. If by-
6/e 
pass or retum line is used, it should terminate at bottom 
of tank to minimize foaming. Do not use air agitation. 
When a range of dosage rates is listed, use the lower 
rates in lighter soils (sandy loams, and soil low in organic 
matter), and the higher rates on heavier soils (clay loams, 
clays, and soils high in organic matter). 
GENERAL WEED CONTROL: To control most weeds for 
an extended period of time on non-cropland such as 
utility, highway, pipeline and railroad right of ways, 
petroleum tank farms, lumberyards, storage areas, 
industrial plant sites, and around farm buildings. 
Apply to these areas at the rate of 5 to 20 Ibs. of 
HELENA BRAND DIURON 80WP per acre to control 
most annual weeds. Use 20 to 60 Ibs. per acre for 
perennial weeds; additional treatment may be required 
where a longer period of control is desired or when hard 
to kill, deep-rooted perennial weeds such as 
Johnsongrass are present. In low rainfall areas, 
HELENA BRAND DIU RON 80WP may not provide 
satisfactory control of deep-rooted perennial weeds. 
For weed control on small areas, use one-half cupful of 
HELENA BRAND DIURON 80WP per 100 sq. ft. for a 
dosage of approximately 50 Ibs. per acre. 
IRRIGATION AND DRAINAGE DITCHES: Apply 5 to 20 
Ibs. per acre to control most annual weeds; use 20 to 60 
Ibs. per acre to control both annual and perennial weeds. 
For irrigation ditches and during the non-cropland season 
and when ditch is not in use. To minimize movement of 
HELENA BRAND DIURON 80WP 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 the 
water to stand for 72 hours; then drain off the water 
before using ditch. Do not treat any ditch into which roots 
of trees or other desirable plants may extend as injury 
may result. 
SELECTIVE USE IN CROPS 
[SEE SOIL LIMITATIONS] 
WEEDS CONTROLLED: HELENA BRAND DIU RON 
80WP as a pre-emergence treatment selectively controls 
germinating seedling weeds in certain crops. Rates of Y. 
to 1 lb. per acre control some annuals including 
crabgrass, barnyardgrass, pigweed, purslane, 
lambquarters, and ragweed. At 1 Y, to 2lbs. per acre, 
seedling weeds, such as bluegrass (poa annual, annual

sweet vemalgrass, foxtail, rattail fescue, red sprangletop, 
velvetgrass, chickweed, com spurry, dog fennel, 
Amsinckia (fiddleneck), gromwell, groundsel, knawel, 
shepherdspurse, tansymustard, wild lettuce, wild 
mustard, annual groud cherry and annual momingglory 
are controlled. In addition, 2 to 6 Ibs. per acre control 
weeds such as annuallovegrass, annual ryegrass, 
sandbur, ricegrass, orchardgrass,com speedwell, 
horseweed, kochia, kyllinga, Mexican clover, 
hawksbeard, peppergrass, pineappleweed, pokeweed, 
rabbit tobacco, ageratum, Spanishneedles and wild 
radish. 
Partial control of quackgrass and horsenettle usually 
occurs with 4 Ibs. per acre; partial control of maiden cane, 
pangolagrass and guineagrass usually occurs with 
treatment at 8 to 10 Ibs. per acre. 
Results vary with soil types (the lower rates are effective 
on the lighter soils and higher rates on heavier soils) and 
environmental conditions. Sufficient moisture in the form 
of rainfall or irrigation is necessary after treatment to carry 
the chemical into the root zone of germinating weeds. 
Any well established weeds should first be eliminated by 
mechanical or other means. For best results, the soil 
should first be eliminated by mechanical or other means. 
For best results, the soil should be well prepared and as 
free as possible from trash and clods. Unless otherwise 
directed, surface of the soil should not be cultivated or 
disturbed after application of HELENA BRAND DIU RON 
80WP as efficiency may be reduce. 
HELENA BRAND DIURON 80WP plus a surfactant is an 
effective treatment of emerged seedling weeds for use as 
a directed post emergence spray in certain crops. Rates 
as low as Y.l 141bs. HELENA BRAND DIURON 80WP 
per acre plus a surfactant controls seedling pigweed. 
Rates 1 1 2 lb. per acre controls seedling weeds such as 
crabgrass, goosegrass, bamyardgrass (watergrass), 
crowfoot, pigweed, purslane, and annual morninggfory. 
Best results are obtained under conditions of high 
humidity and temperatures over 70°F. 
SOIL LIMITATIONS: Crop injury may result from failure 
to observe the following: Unless otherwise directed, do 
not use (1) on light (sand, loamy sand or gravelly) soils or 
exposed subsoils (2) on alfalfa, apples, barley, citrus, 
cotton (pre-plant and lay-by) grapes, olives, pears, 
plumosus fem, sorghum, sugarcane and winter wheat 
where organic matter is less than 1 % (3) on blueberries, 
birdsfoot trefoil, caneberries, gladiolus, and gooseberries 
where organic matter is less than 2%. 
('/,3 
Unless otherwise directed, do not replant treated areas to 
any crops within two years after last application as injury 
to subsequent crops may result. 
CROPS 
ALL RATES ARE EXPRESSED AS BROADCAST 
RATES: where band applications are specified, use 
proportionately less. For example, use 1/3 of the 
broadcast rate when treating a 14' band where row 
spacing is 42'. Unless otherwise directed, surface of soil 
should not be cultivated or distUrbed after application as 
crop injury may result. (SEE SOIL LIMITATIONS) 
ALFALFA: Use in areas where alfalfa becomes winter 
dormant and in areas of California (north of the 
Tehachapi Mountains) where alfalfa becomes semi­
dormant. Use 1 Yo to 3lbs. per acre (except east of the 
Appalachian Mountains use 1 Yo to 2 Ibs.) Apply anytime 
after alfalfa is dormant in the Fall but before crop begins 
growth in the Spring. For control of volunteer alfalfa 
seedlings in the Far West, use 4 Ibs. per acre (SEE SOIL 
LIMITATIONS). 
Treat only stands established for one year or more. Do 
not apply to seedling alfalfa nor to alfalfa grass mixtures; 
do not apply to established alfalfa with unusually shallow 
root penetration (such as shall hard pans, in alkali spots) 
as crop injury may result. 
PACIFIC NORTHWEST: Apply in the Fall after alfalfa 
becomes dormant but no later than mid-December. 
ARIZONA, CALIFORNIA, AND NEVADA: Application 
may be made on dormant alfalfa as late as January. 
EASTERN COLORADO AND KANSAS: For control of 
tansymustard, apply 1 lb. shortly after emergence of 
mustard in the Fall or winter and 2 Ibs. if weeds are 2 to 4 
inches tall. If other annual weeds are present, use 2 to 3 
Ibs. in February or March. 
OTHER AREAS: Where alfalfa becomes winter dormant, 
apply in March or early April before Spring growth begins. 
APPLES AND PEARS: Use only under trees established 
in the orchard for at least 1 year. Apply 4 Ibs. per acre to 
area under individual trees or as a band in the tree row; 
avoid contact of fOliage or fruit (SEE SOIL 
LIMITATIONS). Apply in the Spring (March through 
May). Do not treat dwarf varieties.

FAR WEST: Treatment may be made in winter 
(December through February) or apply 2 Ibs. as 
postharvest treatment followed by 2 Ibs. in the Spring. 
ASPARAGUS: Do not apply to newly seeded asparagus 
nor to young plants during the first growing season after 
setting nor on plants with exposed roots as severe injury 
may result. Apply as a band treatment. On light sandy 
soils and other soils low in clay Qr organic matter, apply 1 
to 2 Ibs. per acre. On soil high in clay or organic matter, 
use 2 to 4 Ibs. 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 provided rainfall is expected. 
When two applications are used in one season, do not 
exceed 3 Ibs. per acre per application. In Washington 
(irrigated crop), apply only a single treatment of 4lbs. per 
acre in late November or December. 
BARLEY (Winter) - WESTERN OREGON AND 
WESTERN WASHINGTON: Apply a single treatment of 1 
1/2 to 2 Ibs. per acre as soon as possible after planting 
but before emergence of barley. Do not apply to cloddy 
or compacted ground where seed is expected or 
improperly planted. Treated areas should not be 
replanted to any rotational crop within 1 year after last 
application as injury to the subsequent crop may result. 
(SEE SOIL LIMITATIONS) 
BIRDSFOOT TREFOIL (lotus) - WESTERN OREGON: 
Treat only established stands at least 1 year old. Apply a 
single treatment of 2 Ibs. per acre when trefoil is dormant 
(October 15 to December 15; See Soil Limitations). Do 
not apply to seedling trefoil as injury may result. Do not 
replant treated areas to any crop within 1 year after 
application as crop injury may result. (SEE SOIL 
LIMITATIONS) 
BLUEBERRIES, CANEBERRIES AND 
GOOSEBERRIES: Apply only to 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. Spray only 
ground at base of bushes: avoid spraying foliage as injury 
may results. (SEE SOIL LIMITATIONS) 
CALIFORNIA· Raspberries, Blackberries, 
Boysenberries, Dewberries, and Loganberries: For 
control of winter annual weeds, apply 2 Ibs. per acre as a 
bond application at base of canes or bushes in October 
or November. A second treatment at the same rate in 
late spring controls summer annuals. A single application 
of 3 Ibs. per acre in January or February will control both 
winter and summer annuals in some areas but the 
separate Fall and Spring schedule are preferred. 
WESTERN WASHINGTON AND WESTERN OREGON­
Blueberries, Caneberries, and Gooseberries: Same 
schedule as recommended in Califomia. (SEE SOIL 
LIMITATIONS) 
INDIANA, MICHIGAN AND OHIO - Blueberries: Make a 
band application of 2 to 4 Ibs. per acre in late Spring but

application as indicated for specific areas, except 
application may be initiated any time for the year where 
sprinkler or flood irrigation can be timed to activate the 
herbicide. Established perennial weeds require other 
special control procedures. Do not apply under citrus 
trees that have been subjected to freezing within 6 
months; do not apply in home plantings of citrus or in 
areas where the roots of other valuable plants or trees 
may extend as injury may result. (SEE SOIL 
LIMITATIONS)

· . 
ARIZONA (except Yuma area) and CALIFORNIA 
(except Imperial and Coachella Valleys) - Oranges, 
Lemons and Grapefruits: Make a single application of 3 to 
4 Ibs. per acre as a broadcast spray shortly after grove 
has been laid up in final form (non-tillage program) in late 
Fall or early Winter. As an alternative, apply 2lbs. per 
acre in October or November and repeat at the same rate 
in March or April. Subsequent annual applications at 2 to 
3 Ibs. will usually give adequate weed control. 
FLORIDA (except Martin, Palm Beach, Broward and 
Dad Counties) - Oranges, Grapefruit, tangelos and 
Tangerines: Apply 4 Ibs. per acre followed by the same 
rate 4 to 6 months later. As an alternative, make a single 
application of 4 to 8 Ibs. per acre. On non-bearing trees, 
treat when winter banks are pulled down. On bearing 
citrus apply any time when seasonal rains are expected. 
For control of paragrass, guineagrass maidencane, 
primrose willow, seamyrtle and loosestrife in ditches 
adjacent to citrus groves, use 1 lb. of HELENA BRAND 
DIU RON 80WP per 1O00 sq. foot (40 Ibs. per acre) using 
sufficient spray volume (at least 4 gals. per 1000 sq. ft.) 
to provide thorough and uniform coverage of the ditch. 
Apply in the spring before weed growth starts or after 
removal of vegetation. Repeat treatment on a spot basis 
to control hard to kill species such as guinesgrass. In 
bedded groves do not treat water furrows between the 
beds as injury to the trees may result. 
TEXAS - oranges and Grapefruit: Apply a single 
treatment of 2 to 4 Ibs. per acre for annual weeds. Use 4 
to 6 Ibs. 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. 
CORN (FIELD) 
POST-EMERGENCE - Apply 3/41b. per acre in 
combination with nonpressure nitrogen solution. If 
nitrogen solution is used, apply 1 lb. HELENA BRAND 
DIURON 80WP per acre and add 1 1 12 pts. of a 
surfactant per 40 gals. spray mixture. Apply as a single 
directed post-emergence spray when the com is at least 
20 inches high and weeds are not taller than 3 inches. 
DO NOT APPLY OVER THE TOP OF CORN. Do not 
replant to any crop within one year except that cotton, 
com and grain sorghum may be planted the spring 
following treatment. 
PRE-EMERGENCE - ARKANSAS, LOUISIANA, 
MISSISSIPPI AND TENNESSEE: Make a single 
treatment of 2 13 to 1 lb. per acre as a broadcast or band 
8/13 
treatment using the higher dosage on heavier soils (loam, 
clay loam). Do not use on light (sand, loamy sand or 
gravelly) soils as injury may result; plant com at least 1 1 
12 inches 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 or 
crop injury may result. 
GLADtOLUS - EAST OF ROCKY MOUNTAINS: Apply 1 
to 2 Ibs. per acre as pre-emergence and or directed post­
emergence treatments. If used for both do not exceed 1 
lb. of HELENA BRAND DIURON 80WP per acre per 
application or a total of 2 Ibs. per season. On cormel 
plantings, apply 2 Ibs. per acre pre- or post-emergence, 
but not more than once. Do not use on cormel plantings 
in Florida; do not spray over top of gladiolus foliage nor 
allow spray to drift onto foliage as injury may result. (SEE 
SOIL LIMITATIONS) 
GRAPES: Apply only to established vineyards (at least 3 
years old) as a band treatment to grape rows. Do not 
apply to vines with trunks less than 1 1 12 inches in 
diameter as injury may result. (SEE SOIL LIMITATIONS) 
NOTE: On soils low in clay or organic matter (less than 
2%) severe plant injury may result if unusually heavy 
rains follow treatment and this risk must be assumed by 
the user. 
EAST OF THE ROCKY MOUNTAINS: On soils low in 
clay or organic matter (1 to 2%), use 2 to 3lbs. per acre: 
on soils high in clay or organic matter, use 3 to 6lbs. 
Apply in the spring just prior to germination and growth of 
annual weeds. 
NEW YORK AND PENNSYLVANIA - CONTROL OF 
PERENNIAL GRASSES: Apply only to established 
vineyards (at least 4 years old) for spot control of 
perennial grasses such as quackgrass, ryegrass and 
orchardgrass as a band treatment to ridered soil (2 to 4 
inches high) under the Trellis at the rate of 8 to 121bs. 
per acre. Bond width should not exceed 3D inches. 
Make one application in the spring of the year and do not 
apply the 8 to 12 Ibs. per acre rate more than once every 
4 years. Use only on heavy soil types such as loams, silt 
loams, 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. 
WEST OF THE ROCKY MOUNTAINS: Apply in 
December, January, or February. For initial treatment, 
make a single application of 3 to 4lbs. per acre 
subsequent annual applications of 2 Ibs. will usually give

adequate weed control. As an altemative to the above 
schedule, apply 2 Ibs. of HELENA BRAND DIURON 
8DWP per acre in October or November and repeat 
application at the same rate in March or April. 
GRASS SEED CROPS (Perennial): In areas as 
specified, apply only to established plantings at least 1 
year old. In fields where ash residues have accumulated 
from buming straw use 3 Ibs. per acre: spread unbumed 
chaff or straw with harrow or chopper before application. 
COLORADO, KANSAS, NEW MEXICO AND 
OKLAHOMA: On switchgrass, side oats grama and sand 
bluestem, apply 2 or 3 Ibs. 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 buming straw, use chopper before 
application. 
conON 
(SEE SOIL LIMITATIONS) 
PRE·PLANT: ARIZONA AND CALIFORNIA ONLY: 
Apply 1 to 2 1/2 Ibs. per acre as a broadcast spray after 
furrows for pre·planting irrigation have been formed; 
apply either just prior to planting or after the pre·planting 
irrigation but before seed beds are dragged off in 
preparation for planting. (SEE SOIL LIMITATIONS) 
Prior to planting, drag off the top of the seed bed and 
plant in untreated soil. Treated soil is retumed to the bed 
after planting when irrigation furrows are reformed. If 
more than 2 furrowing out operations are performed prior 
to lay·by weed control in the furrow bottoms may be lost. 
A lay·by application also may be made but the combined 
total per season must not exceed 1.2 Ibs. HELENA 
BRAND DIURON 8DWP per acre on sandy loam, nor 2.2 
Ibs. HELENA BRAND DIURON 8DWP per acre on clay. 
PRE·EMERGENCE (EXCEPT ARIZONA AND 
CALIFORNIA): Make a single application as a broadcast 
or a band spray after planting but before cotton emerges. 
Use at the following rates:

Silty clay and clay 2.0 1.6 
'Do not use on sand as crop injury may result. Do not 
treat cotton in deep furrows as crop injury may result. 
BAND TREATMENT 
Use proportionately less: for example, for 14 inch band 
on 42 inch row, use 1/3 of broadcast rate. 
Apply immediately after cotton is planted: wherever 
possible, planting and spraying should be combined in 
one operation. For best results, soil should be well 
prepared and as free as possible from trash and clods. 
Shallow incorporation (no deeper than 1/4 inch) with a 
rotary hoe or similar equipment following planting usually 
improves results particularly during dry weather. 
A wide press wheel following planting should be used to 
provide a level seed bed for subsequent early season 
post-emergence treatments. 
Treatment usually provides weed control for a period of 3 
to 8 weeks. Sufficient moisture (usually 1 to 2 inches) in 
the form of rainfall or irrigation is necessary after 
treatment to carry the chemical into the root zone of 
germinating weeds; best results are obtained when this 
occurs within 2 weeks after application. If moisture is 
insufficient to activate HELENA BRAND DIURON 8DWP 
or if soil becomes crusted before crop emerges, a shallow 
rotary hoeing (no deeper than 1/4 inch) should be made 
before weeds become well established. If initial seeding 
fails to produce a stand, cotton may be replanted in soil 
treated with HELENA BRAND DIURON 8DWP. 
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 deep, do 
not retreat field with a second pre-emergence application 
of HELENA BRAND DIURON 8DWP during the same 
crop year as injury to the crop may result.

, ' 
POST-EMERGENCE: EARLY SEASON: Apply in 
combination with surfactant as a directed spray when 
cotton is at least 6 inches tall and when weeds do not 
exceed 2 inches in height, a second application may be 
made if needed. Control of weeds under drought stress 
or over 2 inches in height is usually impractical. Apply as 
a band treatment only, directing spray to cover weed 
foliage. DO NOT SPRAY OVER lOP OF COTTON. 
Use pressure of 20 to 25 psi and adjust nozzles to 
minimize contact of cotton leaves with spray or drift, or 
crop injury may result.

HELENA BRAND DIU RON BOWP (1 to 2lbs. in Arizona 
and Califomia in 25 to 40 gals. water per acre as a 
directed spray) (SEE SOIL LIMITATIONS). Apply when 
cotton is at least 12 inches high (at least 20 inches for 
Pima 5-2). Keep contact of spray or drift on cotton plants 
to a minimum. DO NOT SPRAY OVER TOP OF 
COTTON. For control of germinating weed seedlings, 
apply immediately after last cultivation, directing spray to 
cover the soil beneath after last cultivation, directing 
spray to cover the soil benealh cotton plants and between 
rows. Altematively, for control of emerged annual weeds 
(4 inches or less in height) at lay-by time, add 1 pt. 
surfactant for each 25 gals. spray; apply as a directed 
spray to cover weed foliage beneath cotton plants and 
between rows. NOTE: Treatment of 1/2 to 3/4 lb. 
HELENA BRAND DIURON BOWP per acre plus 
surfactant followed by the same treatment later, if 
needed, may be used as an alternate to the preceding 
recommendation. 
In irrigated cotton, best pre-emergence weed control is 
obtained if 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.

per acre as injury to subsequent crops may result 0.8 Ibs. 
on loamy sand; 1.21bs. on sandy loam, 1.61bs. on clay 
loams: and 2.2Ibs. on clay. 
WESTERN OREGON: On alta fescue, highland 
bentgrass, Astoria bentgrass, orchardgrass, Kentucky 
bluegrass (Merion bluegrass), apply 2 to 4 Ibs. per acre 
between October 1 and November 15. In fields where 
ash residues have accumulated from buming straw, use 
3 to 4 Ibs. per acre: spread unburned chaff or straw with a 
harrow or chopper before application. If perennial 
velvetgrass (Holcus lanatus) is a problem, use 4 Ibs. per 
acre. 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 sands of spring planted alta 
fescue orchardgrass and Kentucky bluegrass may be 
treated the following fall provided the crop is planted 
before April 1 and treatment is not applied before October 
15 use HELENA BRAND DlURON BOWP at 2 Ibs per 
acre. 
OLIVES - CALIFORNIA: Use only under trees 
established in the grove for at least 1 year. Do not apply 
in areas where roots of other valuable plants or trees may 
extend as injury may result. Apply 2 Ibs. per acre after 
the grove is laid up in final form in late October or 
November. A second application is 2 Ibs. per acre should 
be made in March or April. Remove weed growth prior to 
treatment. Avoid contact of foliage with spray of drift. 
SEE SOIL LIMITATIONS

PINEAPPLE - HAWAII: Apply 4 to 8 Ibs. per acre as a 
broadcast spray immediately after planting and prior to 
weed emergence. Use 4lbs. per acre after harvesting 
plant crop (for 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 Ibs. per acre 
at intervals of not less than 2 months. Additional 
applications to plant crop may be.made as needed to 
interspace using 2 Ibs. per acre .. Do not apply more than 
3 broadcast sprays (maximum 12 Ibs. per acre) prior to 
differentiation not more than 16 Ibs. per acre per plant 
crop. Treated areas may be planted to pineapple or 
sugar cane 1 year after last application. 
PLUMOUS FERN - FLORIDA: Treat only established 
stands at least 1 year old. Apply 3lbs. per acre following 
hand weeding and 3 to 5 days after mowing of fern (SEE 
SOIL LIMITATIONS). Do not cultivate or disturb soil after 
application as crop injury may result. 
SORGHUM (GRAIN) - SOUTHWESTERN STATES: 
Apply 1 14 to 1/2 lb. per acre as a directed post­
emergence broadcast or band treatment after sorghum is 
15 inches tall to control weed 2 to 4 inches in height. DO 
NOT SPRAY OVER TOP OF SORGHUM. Add 1 pt. of a 
surfactant per 25 gals. spray. Apply at spray pressures of 
20 to 25 psi to minimize drift. Use lower rate on 
broadleaved weeds up to 2 inches tall. Use the higher 
rate on grasses up to 2 inches and broad leaved weeds 
up to 4 inches tall. When the lower rate is used a second 
application may be made if needed provided that the total 
herbicide applied in one crop year does not exceed 1 12 
lb. of Diuron 80WP per acre. Treatment of weeds under 
drought stress is usually ineffective. Do not replant 
treated areas to crops other than cotton or com within 4 
months following band treatments and 6 months following 
broadcast treatment as crop injury may result. (SEE 
SOIL LIMITATIONS) 
SUGAR CANE: To prevent possible crop injury on-new 
cane varieties. Tolerance to HELENA BRAND DIURON 
80WP should be determined prior to adoption as field 
practice. Do not treat sugar cane growing on thinly 
covered sub-soils or rocky areas as crop injury may 
result: see Soil Limitations. Temporary chlorosis of the 
crop may result from application over emerged cane: to 
minimize chlorosis. Use directed post-emergence 
sprays. (SEE SOIL LIMITATIONS) 
FLORIDA: For high organic soils, apply 2 to 4 Ibs. per 
acre as a broadcast or band spray prior to weed 
emergence after planting or after harvesting plant crop 
11/,3 
(for ratoon crop). A second and third application of 2lbs. 
per acre may be made as needed by directed spray inter 
row. Do not apply more than 3 treatments nor more than 
6 Ibs. total per acre between planting (or ratooning) and 
harvest. 
HAWAII AND PUERTO RICO: Apply 4 to 8 Ibs. per acre 
as a broadcast spray prior to weed emergence after 
planting or after harvesting plant crop (for ratoon crop). A 
second and third application of 2 to 4 Ibs. 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 
mixture at the rate of 1 to 2 qts. per 100 gals. and apply 
as a directed spray. DO NOT SPRAY OVER TOP OF 
CANE. 
Do not apply more than 3 treatments nor more than 10 
Ibs. (Puerto Rico) or 121bs. (Hawaii) total per acre 
between planting (or ratooning) and harvest. Treated 
areas may be planted to sugar cane or pineapple one 
year after last application. 
LOUISIANA: Use on plant cane seeded on followed 
ground. Make a single application of 3 to 3 3/4 Ibs. per 
acre at either of the following times: FALL TREATMENT 
(August through October). Treat a 2 ft. band over the row 
after planting of cane but before weeds or cane emerge. 
SPRING TREATMENT band over the row before weeds 
or can emerge. 
WHEAT (WINTER): Seed bed must be well prepared 
before pre-emergence application. Crop injury may result 
if application is made to ground which is cloddy or 
compacted, resulting in exposed or improperly planted 
seed. Whenever seed bed preparation and planting are 
carried out during abnormally dry weather, resulting in a 
surface layer of dust over planted seeds application 
should not be made until the dust is settled by rainfall or 
irrigation. (SEE SOIL LIMITATIONS) 
Do not use on thinly covered or exposed sub-soil areas 
(clay knobs) as injury to the crop may result: see Soil 
Limitations. Treated areas should not be replanted to any 
other crop within 1 year after last application as injury to 
the subsequent crop may result. 
Do not apply post-emergence treatments where winter 
climatic conditions have caused heaving of wheat plants 
or after wheat has reached the boat stage as injury to the 
crop may result.

KANSAS, OKLAHOMA AND TEXAS: Make a single 
post-emergence application at the rate of 1 112 to 2 Ibs. 
per acre. Apply 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. 
WASHINGTON, OREGON AND IDAHO - EAST OF 
. CASCADE RANGE: Make a single application at the rate 
of 1 to 1 1/2Ibs. per acre. 
In areas having an average annual rainfall exceeding 16 
inches. 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 usually give good 
results. Provided weed growth is less than 4 inches tall. 
Application later than May 1 may give poor results. 
In areas having an average annual rainfall from 10 to 16 
- inches. FALL OR WINTER TREATMENT - After wheat 
is planted in the fall apply when sufficient moisture is 
available to germinate wheat seed. Make application 
before weeds are 2 inches tall and before the soils 
freezes. 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 with 
HELENA BRAND DIURON 80WP 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 
inches prior to planting. Do not retreat field with a second 
application of HELENA BRAND DIURON 80WP during 
the same crop year or injury to the crop may result. 
WEST OF CASCADE RANGE: Make a single application 
at the rate of 1 1/2to 2 Ibs. per acre. Apply as soon as 
possible following planting. If wheat and weeds have 
emerged apply before weeds are 3 to 4 inches tall.
