SPRAY DRIFT MANAGEMENT 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related factOIs 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 fores\Jy applications, public health uses 01 to applications using dry formulations. 
1. The distance of the outer most nozzles on the boom must not exceed % 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 status 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 Advisorv 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, iiut will not prevent drift if applications are made improperty, 
or under unfavorable environmental conditions (see Wind, Temperature, and Humidity, and Temperature Inversions). 
COIltrOllinll Droplet Size 
• Volume-Use high flow rate nozzles to apply the highest practical spray volume. Nozzles 
With higher rated flows p(oduce 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 
in,:reasing 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 Iow-drift nozzles. Solid steam nozzles oriented straight back 
pr,oduce the largest droplets and the lowest drift. 
• Boom Length - For some use pattems, reducing the effective boom length to less than 314 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 lop of the largest plants unless a greater height is 
required for aircraft satety. 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 polenti~11 is lowest between wind speeds of 2-10 mph. However. many lactors, including droplet size and equipment type determine drift . 
potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. NOTE: Local 
terrain can influence wind pattems. Every applicator should be familiar with local wind pattems 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 temperalures 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

'. . 61'~ 
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 thai layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upwards 
and rapidly disslpates 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-talget aops) is minimal (e.g., when wind is blowing away from the sensitive areas). 
GENERAL INFORMATION 
HELENA BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE is allowable fonnulation to be mixed in water and applied as a spray for selective 
control of weeds in cer1ain aops and for nonselective control of weeds in cer1ain aops and for nonselective weed control on IlOIH:I'OpIand areas. tt 
is non-cormsive to equipment nonflammable and nonvolatile. 
HELENA BRAND 4.8 LB. DIURON FLOWABlE HERBICIDE 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 soil low in clay or organic matter to obtain equivalent 
herbicide performance. Moisture is required to activate the chemical; best resutts oocur if rainfall (or sprinkler irrigation) oocurs within 2 weeks of 
application. 
HELENA BRAND 4.8 LB. DIU RON FLOWABLE HERBICIDE may also be used to control emerged weeds. Resutts vary with rale applied and 
environmental conditions; best results are obtained on succulent weeds growing un~ ,conditions of high humidity and temperatures of 70°F or 
higher. Addition of a nonionic surfactant inaeases contact effects of HELENA BRAND 4.8 LB, DIURON FLOWABLE HERBICIDE. Since the effect 
of HELENA, BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE varies with soils, uniformity of application, and environmental conditions, it is 
suggested that growers limit their first use to small areas. Observe all cautions and fimitations on labeling of all products used in mixtures.

POSTEMERGENCE USE (Emerged Seedling Weeds): HELENA BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE at recommended rates, 
controls annual weeds such as annual momingglory, bamyarograss (watergrass), crabgrass, Q'Owfoot, goosegrass, pigweed and purslane. Addition 
of a nonionic surfactant to the spray (where recommended) increases contact effects of HELENA BRAND 4.8 LB. DIURON FLOWABLE 
HERBICIDE. Best results are obtained on succulent weeds growing under conditions of high humidity and temperatures of 70°F or higher. 
EQUIPMEIIT - Spray volumes and Pressures: Use a tractor-mounted fixed-boom power sprayer properly caHbrated to a constant speed and rate 
of detivery. Openings in screens should be equal to or larger than 50 mesh. Continuous agitation in the spray tank is required to keep the material 
in suspension. Agitate by mechanical or hydraulic means; if by-pass or retum lines is used, it should terminate at bottom of tank to minimize 
foaming. Avoid overlapping, and shutoff spray booms while starting, tuming, slowing or stopping, or injury to the Q'Op may resu~. 
For pree!I1E!Igence application, use 25 to 40 gallons per acre and spray pressure of 30 to 40 psi. For postemergence application, use sufficient 
volume (min. 25 gals per acre) for thorough coverage of weed foliage; use spray pressure of 20 to 25 psi to keep drift to a minimum. 
Aerial: For alfalfa, asparagus, barley (winter), cotton (preplant or preemergence only), grass seed crops, pineapple, sugarcane and wheat (winter), 
application may be made by aircraft (5 to 10 gals. 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. 
SPRAY PREPARATION: Mix proper amount of HELENA BRAND 4.8 LB. DIURON FLOWABLE HERBICIDE into necessary volume of water, 
where use of nonionic surfactant is recommended, dilute with 10 parts of water and add as last ingredient to nearly full tank. 
Use Rates: All dosages of HELENA BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE ate expressed as broadcast rates; for band treatment,use 
proportionalely less. For example, use 1/3 of the broadcast rate when treating a 14' band where row spacing is 42'. Where a range of dosages is 
given, use the lower rate on coarse textured soils (low in clay or organic matter) and the. higher rate on fine textured soils (high in clay or organic 
matter); for postemergence application, use the lower rate on smaller weeds and the higher rate on larger weeds. 
SOIL LlMn'ATIONS: Crop injury may resuH from failure to observe the following: 
Unless othE!rwise directed, do not use on sand, loamy sand, gravelly soils or exposed subsoils; nor on pecans where organic matter is less than %%; 
nor on alfalfa, apples, artichoke, barley (winter), bermudagrass pasture, citrus, cotton, grapes, oats, olives, papayas, peaches, pears, plumosus fern, 
sorghum, sugarcane, walnuts and wheat (winter) where organic matter is less than 1 %; nor on blueberries, birdsfoot trefoil, caneberries, 
gooseberriE!S, macadamia nuts and peppermint where organic matter is less thah 2%. 
REPLANTII~G: Unless otherwise directed. do not replant treated areas to any crop within 2 years after last application as injury to Subsequent Q'OPS 
may result. 
FIELD CRC.PS (See Soil Limitations) 
A good seedbed must be prepared before preernergence use of HELENA BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE 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 soils should not be cultivated or disturbed after application of HELENA BRAND 4.8 LB. DIURON FLOWABLE 
HERBICIDE and before emergence of the crop as weed control may be reduced and Q'Op injury may resull However, if moisture is insufficient to 
activate the hertlicide, 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 affaffa-grass mixtures; do not apply to alfaffa 
under sires, from disease, insect damage, shallow root penetration (such as on shallow hard pans), alkafi spots; nor to flooded fields as Q'Op injury 
may resull Do not spray on snow covered or frozen ground.

Idaho, Omgon, Washington: Use 1 to 2 q1s. per acre; for control of volunteer aIIaIfa, use 2 213 q1s. per acre. Apply in fall after alfalfa becomes 
dormant no later than mid-December. 
California (Dormant and Semi-Dormant Varieties): Use 1 to 2 q1s. per acre; for control of volunteer alfalfa, use 2 213 q1s. per acre .. Apply in fafl or 
winter after aIIaIfa becomes dormant or semi-dorman~ btlt before growth begins in the spring. Crop injury may result n application is made to 
actively gmwing ·alfalfa. For best resulls, apply before weeds have emerged or become established (2" in height or diameter). Control of established 
HELENA BRAND 4.8 LB. DIURON FLOWABLE HERBICIDE with a suitable contact herbicide registered for such use. Sufficient rainfall for soil 
activation of HELENA BRAND 4.8 LB. DIU RON FLOWABLE HERBICIDE is unlikely in California after February 1. Treated areas may be replanted 
to any crop after one year from last application if rate does not exceed. 1 1/3 q1s. per acre. 
Arizona, Nevada: Use 1 to 2 q1s. per acre; apply in fall after alfalfa becomes dormant btlt no later than January. 
Eastern Colorado, Kansas: For control of tansymus1ard, apply 213 q1s. per acre shortly after emergence of mus1ard in the fall or winter; use 11/3 
q1s. per acre if weeds are 2" to 4' in height Alternatively, if other annual weeds.ara presen~ apply 1 1/3 to 2 q1s. per acre in February or March. 
Other Are.1S Where Alfalfa Becomes Winter Dormant: Use 1 to 2 qls. per acre (1 to 11/3 q1s. per acre East of Appalachian Mountains). Apply in 
March or early April, but before spring growth begins. 
ART/CHOI<E - CalHornia: Apply 1 1/3 to 2 213 qls. per acre in late fall to eSriy winter after the last aJltivaIion. Apply before weeds germinate or to 
emerging seedlings. Direct spray to cover the areas between the rows and at the base of the artichoke planls, keeping contact with crop planls at a 
minimum. 
ASPARAGUS: Apply as a band or broadcast treatment Do not apply to young planls during the first growing season (except as noted below), nor 
to newiy seeded asparagus, nor on plants with exposed rools as severe injury may result. . 
Established Plantings: On lightly sandy soils and other soils low in day or organic matter, apply 213 to 11/3 qls. per acre. On soils high in day or 
organic matter, use 11/3 to 2 213 qls. per acre. Two applications may be used; the first application should be made before weeds become 
established btlt no ea~ier than 4 weeks before spear emergence and no later than the early cutting period (n weeds are controlled into the aJlling 
period by cultural practices; application may be delayed until immediately after Jhe last aJltivation); a second application may be made immediately 
following completion of harvest provided rainfall is expected. When two applications ara used in one season, do not exceed 2 qls. per acre per 
application. In Washington (irrigated aops); apply a single treatment of 2 213 qts. per acre. If treatment is delayed until late winter or ea~y spring, 
incorporation of the chemical in the top l' to 2' of soil may substitute for lack of rain to activate the herbicide. 
Newly Planted Crowns - California (San Joaquin Delta): Make a single application of 1 1/3 to 2 213 per acre on soils high in day or organic 
matter; use the lower rate on day loams and the higher rate on peat soils. Do not use on soils containing less than 2% organic matter. Soil must be 
settled by ~ainfall or irrigation prior to treatment Do not treat aowns.planled to depth of less than 2#. 
BARLEY, WINTER (Drill,Planted) - Western Oregon and Western Washington: Make a single application of 1 to 1 1/3 qts. per acre as soon as 
possible afler planting but before emergence of barley. Do not repiant treated areas to any crop within 1 year after last application as injury to 
subsequent aops may result 
BERMUDA.GRASS PASTURES (Newly Sprigged): Apply 213 to 2 qls. after planting and before emergence of bermudagrass or weeds. 
Alternatively, for control of emerged annual weeds up to 4' in heigh~ apply 1/3 to 213 qts. per aae; add 1 pt of an approved non~onic suriactant per 
25 gals. of spray. If bermudagrass has emerged at time of treatrnen~ temporary bum of exposed plant parts may 0CaJr. 
Plant sprigs (stolons) 2' deep in a well-prepared seed bed; do not treat areas where springs are planted less than 2' deep as aop injury may result 
Do not gr8l:e or feed foliage from treated areas to livestock within 70 days after application. 
BIRDSFOC'T TREFOIL (Lotus) - Western Oregon: Treat only stands, established for at least 1 year; do not apply to seedling trefoil as injury niay 
resuH. MaI;e a single application of 11/3 qt per acre when trefoil is dormant (October 15 to December 15). Do not replant treated areas to any aop 
within 1 year after last application as injury to subsequent aops may result. 
CORN (FIE LO) 
Postem8f94Klce - Make a single application of 1 qt per acre in combination with non-ionic pressure nitrogen solution. If nitrogen solution is not 
used, apply 213 qt per acre; add 1 pt of an approved non-ionic suriactant per 25 gals of spray. Apply as a directed sprey when com is at least 20'

HELENA BRAND 4.8 LB. DIURON FLOWABLE HERBICIDE is an effective herbicide for the control of many annual and perennial grasses and 
herbaceous weeds on non-aopland areas where bare ground is desired. The degree of control and duration of effect will vary with the amount of 
chemical applied, soil type, rainfall and other conditions. 
HELENA BRAND 4.8 LB. DlURON FLOWABLE HERBICIDE may be used as a pre-emergence treatment at any time of the year except when 
ground is fnlzen, provided adequate moisture is supplied by rainfall or artificial means to activate the herbicide. Best results are obtained if 
application is made to the soil sho~ before weed growth begins. If dense growth is present, remove tops and spray the ground. 
Increase contact activity on established weeds may be obtained by the addition of an approved non-ionic surfactant at the rate of 2 qls. per 100 gals. 
of spray milrture. Apply as a drenching spray to actively growing weeds during warm weather when daily temperature will exceed 70 degrees F. 
Observe all cautions and limilations on labeling of all producls used in mixtures.
