Helena Agri-Enterprises, LLC intends that this product may not be used for manufacturing products for application to turf and ornamentals.
To delay herbicide resistance take one or more of the following steps:
Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 3
Helena Agri-Enterprises, LLC does not recommend or authorize the use of this product in manufacturing, processing or preparing custom blends 
with other products for application to field and row crops or to orchard, grove, and vineyard crops.
DO NOT enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 24 hours.
Exception: if the product is soil injected or soil incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter 
the treated area if there will be no contact with anything that has been treated.
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to 
herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g., higher crop seeding rates; 
precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) and 
other management practices.
Rotate the use of Omni Brand Pendimethalin 3.3 EC or other Group X herbicides within a growing year sequence or among growing 
seasons with different herbicide groups that control the same weeds in a field.
If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another 
management strategy or herbicide with a different mode of action, if available.
Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or integrated weed­
management recommendations for specific crops and weed biotypes.
Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is 
available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone 
partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone 
to resistance.
Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possible herbicide 
resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is 
achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with 
controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative 
herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other 
fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.
For further information or to report suspected resistance, contact Helena Agri-Enterprises, LLC representatives at 901-761-0050 or at 
www.helenaagri.com.
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This standard contains 
requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It 
contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions

apply to uses of this product that are covered by the Worker Protection Standard.
RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management. Omni Brand Pendimethalin 3.3 EC is a pendimethalin (Group 3 herbicides). Any weed population may contain or 
develop plants naturally resistant to Omni Brand Pendimethalin 3.3 EC and other Group 3 herbicides. The resistant biotypes may dominate the weed 
population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has 
been treated, such as plants, soil, or water, is:
• Coveralls
• Chemical-resistant gloves made of barrier laminate, butyl rubber 14 mils, nitrile rubber > 14 mils, neoprene rubber > 14 mils, or Viton 14 
mils
• Shoes plus socks

Prevent an influx of weeds into the field by managing field borders.
Apply this herbicide at the correct timing and rate needed to control the most difficult weed in the field.
Filename: Omni Braud Pendimethalin 3,3 EC (5905-AUU) 012821 CLN
Use a broad spectnim soil-applied herbicide with a mechanism of action that differs from this product as a foundation in a weed-control program. Do 
not use more than two applications of this or any other herbicide with the same mechanism of action within a single growing season unless mixed 
with an herbicide with another mechanism of action with an overlapping spectrum for the difficuit-to-control weeds.
Prevent fie!d-to-fie!d and within-field movement of weed seed or vegetative propagules. Thoroughly clean plant residues from equipment before 
leaving fields.

Over application can result in crop-stand loss, crop injury, or soil residues.
Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 5
Seedling diseases, cold weather, excessive moisture, shallow or deep planting, low or high soil pH, high soil salt concentration, or drought can 
weaken seedlings and plants and increase the possibility of crop damage from OMNI BRAND PENDIMETHALIN 3.3. Under these conditions, crop 
yields can be reduced.
Unusually cold, excessively wet, or hot and dry conditions that delay germination or extend germination over a long period of time can reduce weed 
control.
Uneven application or improper soil incorporation can decrease weed control or cause crop injury. Soil incorporation deeper than recommended can 
reduce weed control.

Application Timings
OMNI BRAND PENDIMETHALIN 3.3 EC will provide most effective weed control when applied by ground or aerial equipment and subsequently 
incorporated into soil within 7 days after application by rainfall, sprinkler irrigation, or mechanical tillage prior to weed seedling emergence from soil. 
OMNI BRAND PENDIMETHALIN 3.3 EC can also be applied through chemigation, including flooded basin irrigation systems. OMNI BRAND
PENDIMETHALIN 3.3 EC is recommended for preplant surface, preplant incorporated, surface incorporated, preemergence, early postemergence, 
postemergence incorporated (CULTI-SPRAY) or layby treatment. See Crop-specific Information for specific application directions by crop.
Application Rate
Use rates for OMNI BRAND PENDIMETHALIN 3.3 EC when used alone, in tank mix, or sequential applications are given in Crop-specific 
Information. Use rates of this product vary by soil texture and organic matter. See Table 2 for soil texture groupings used in this label.
Preplant Surface Applications: For use in minimum tillage or no-tillage production systems, apply OMNI BRAND PENDIMETHALIN 3.3 EC alone 
or in tank mixes up to 45 days before planting. When making early preplant surface applications (15 to 45 days prior to planting), OMNI BRAND
PENDIMETHALIN 3.3 EC should be tank mixed or followed by a postemergence herbicide application. Rainfall or sprinkler irrigation within 1 days 
after application is required to move this product into the upper soil surface where weed seeds germinate.
"Suppression
Not controlled in California.
Mode of Action
OMNI BRAND PENDIMETHALIN 3.3herbicide is a meristematic inhibitor that interferes with the plant's cellular division or mitosis. This and/or other 
products with the meristematic inhibiting mode of action may not effectively control naturally occurring biotypes of some of the weeds listed on this 
label. A weed biotype is a naturally occurring plant within a given species that has a slightly different, but distinct, genetic makeup from other plants. 
Other herbicides with the meristematic inhibiting mode of action include other dinitroaniline herbicides, such as trifluralin. If naturally occurring 
meristematic inhibiting resistant biotypes are present in a field, OMNI BRAND PENDIMETHALIN 3.3 EC and/or any other meristematic inhibiting 
mode of action herbicide should be tank mixed or applied sequentially with an appropriate registered herbicide having a different mode of action to 
ensure control.
Surface Incorporated Applications: Uniformly apply OMNI BRAND PENDIMETHALIN 3.3 EC as broadcast or banded treatment to soil surface 
underneath established trees and/or in ground areas between trees rows. Within 7 days after application, incorporate into upper (1 inch to 2 inch) soil 
surface using either rainfall, sprinkler irrigation, or shallow mechanical incorporation using an implement capable of giving uniform incorporation; two- 
pass mechanical incorporation usually results in a more consistent result.
Preemergence Surface Applications: Broadcast treatment uniformly to the soil surface at planting and up to 2 days after planting. Rainfall, 
sprinkler irrigation, or shallow mechanical incorporation within 7 days after application is required to move this product into the upper soil surface 
where weed seeds germinate. If adequate rainfall or irrigation does not occur and weed seedling emergence begins, a shallow cultivation or rotary 
hoeing will improve performance.

Mandatory Spray Drift
Spray Drift Advisories
Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 7
Ground Applications
Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy.
For all applications, applicators are required to use a medium to ultra coarse spray droplet size (ASABE S572.1).
Do not apply when wind speeds exceed 10 miles per hour at the application site.
Do not apply during temperature inversions.
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
Controlling Droplet Size - Aircraft
Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles should be 
oriented parallel with the airflow in flight.
Layby Application: Apply OMNI BRAND PENDIMETHALIN 3.3 EC directly to the soil between rows as a directed spray following the last normal 
cultivation (layby). See Crop-specific Information for more details on layby application.
Aerial Applications
Do not release spray at a height greater than 10 ft above the vegetative canopy, unless a greater application height is necessary for pilot safety. 
For all applications, applicators are required to use a medium to ultra coarse spray droplet size (ASABE S572.1).
The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade diameter for helicopters.
Applicators must use Yz swath displacement upwind at the downwind edge of the field.
Nozzles must be oriented so the spray is directed toward the back of the aircraft.
Do not apply when wind speeds exceed 10 miles per hour at the application site.
Do not apply during temperature inversions.
Controlling Droplet Size - Ground Boom
Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical spray volume for the 
application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate.
Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size.
Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.
Split Applications: OMNI BRAND PENDIMETHALIN 3.3 EC may be applied preplant incorporated up to 60 days prior to planting and followed by a 
preemergence application at planting or up to 2 days after planting. The total amount of OMNI BRAND PENDIMETHALIN 3.3 EC herbicide applied 
per acre per year cannot exceed the highest labeled rate for any given soil type. See Crop-specific Information for more details on split 
applications.
Fall Applications: OMNI BRAND PENDIMETHALIN 3.3 EC may be used in fall application programs in certain crops. See Crop-specific 
Information for details on fall application timing.
Postemerqence Incorporated Applications (CULTI-SPRAY): Prior to application, crop must be cultivated in such a manner as to throw at least 
one inch of soil over the base of the crop plants. This will prevent direct contact of OMNI BRAND PENDIMETHALIN 3.3 EC and the zone of brace 
root formation. OMNI BRAND PENDIMETHALIN 3.3 EC must be applied broadcast with a ground sprayer when crop is at least 4 inches tall up to 
layby. Use drop nozzles if crop foliage will prevent uniform coverage of the soil surface within the rows. Thoroughly and uniformly incorporate OMNI 
BRAND PENDIMETHALIN 3.3 EC treatments into the soil with:
(1) a sweep-type or rolling cultivator set to provide thorough incorporation in the top 1 inch of soil, or
(2) adequate overhead irrigation water or rainfall. See Crop-specific Information (Corn and Grain Sorghum) for more details on (CULTI-SPRAY) 
application.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying larger
droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental 
conditions.

Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 8
BOOM HEIGHT - Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground equipment, the boom should 
remain level with the crop and have minimal bounce.
RELEASE HEIGHT-Aircraft
Higher release heights increase the potential for spray drift. When applying aerially to crops, do not release spray at a height greater than 10 ft above 
the crop canopy, unless a greater application height is necessary for pilot safety.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with altitude and are 
common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of 
smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind 
conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during 
temperature inversions.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not interfering with the 
uniform deposition of the spray on the target area.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

Aerial Applications
Uniformly apply in 5 or more gallons of water per acre. Exercise caution to minimize drift. DO NOT apply during periods of gusty winds or when wind 
conditions favor drifting. Spray drift can cause injury to sensitive crops. It is recommended that a flagman or an automatic mechanical flagging unit 
on the aircraft be used to avoid overlapping and possible crop injury.
Use the following formula to determine the amount (in pints) of OMNI BRAND PENDIMETHALIN 3.3 EC to be impregnated on a ton of dry bulk 
fertilizer based on the rate of fertilizer to be applied per acre:
Ground Applications (Broadcast)
Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre or 20 or more gallons of liquid fertilizer per acre. 
Use sprayers equipped with appropriate nozzles that provide uniform and accurate spray distribution and minimize drift. Keep the bypass line on or 
near the bottom of the tank to minimize foaming. Nozzle and in-line screens must be no finer than 50 mesh. Application of OMNI BRAND 
PENDIMETHALIN 3.3 EC during periods of gusty winds may result in uneven applications. DO NOT apply OMNI BRAND PENDIMETHALIN 3.3 EC

If liquid fertilizer/herbicide(s) mixture separates in the spray tank, clogged equipment and uneven application can result. Always predetermine the 
compatibility of OMNI BRAND PENDIMETHALIN 3.3 EC alone or with other herbicides based on the following compatibility “jar test":
Add 1 pint of fertilizer to a quart jar.
Add 1 to 4 teaspoon(s) of the Dry Flowable (DF), Wettable Powder (WP), Aqueous Solution (AS), Flowable (F) or Liquid (L) formulation 
(depending on mixing ratio required) to the liquid fertilizer. The number of teaspoons of the formulation to add can be determined by the 
following formula:
X Broadcast Rate 
per Acre
Ground Applications (Dry Bulk Fertilizer)
Apply OMNI BRAND PENDIMETHALIN 3.3 EC/dry bulk fertilizer mixtures only with ground equipment. DO NOT impregnate OMNI BRAND 
PENDIMETHALIN 3.3 EC onto coated ammonium nitrate or limestone because these materials will not absorb the herbicide. Dry fertilizer blends 
containing mixtures of ammonium nitrate or limestone may be impregnated with OMNI BRAND PENDIMETHALIN 3.3 EC. A minimum of 200 
pounds of impregnated dry bulk fertilizer, excluding the weight of ammonium nitrate or limestone, must be applied per acre.
Ground Applications (Band)
Uniformly apply the broadcast equivalent rate and volume per acre. To determine these:
X Broadcast Volume = Band Volume 
per Acre per Acre
Close the jar and agitate until the herbicide(s) are evenly dispersed in the liquid fertilizer. If the materials DO NOT disperse well, it may be 
necessary to slurry the chemicals in water before adding to the fertilizer.
After dispersing the materials, add appropriate number of teaspoons of OMNI BRAND PENDIMETHALIN 3.3 EC to the jar and shake well. Add 
water soluble concentrate herbicides to the mixture last and agitate. Let the mixture stand for 30 minutes and then observe the results. Look for 
signs of separation: an oily layer or globules, sludge, flakes or other precipitates.
Evaluate compatibility.
• If the herbicide(s) and liquid fertilizer mixture does not separate, use this mixture in your spray tank.
• If the mixture separates but mixes readily with shaking, the mixture can be used provided that good agitation is maintained in the spray 
tank.
• If separation of the mixture occurs and agitation does not correct this problem, a compatibility agent is needed.
If the need for a compatibility agent is demonstrated, the following procedure is recommended: Using a clean quart jar, repeat step 1 above and 
add Vz teaspoon of the compatibility agent to the liquid fertilizer. Mix well and repeat steps 2,3 and 4. If separation or precipitation occurs with 
the compatibility agent, DO NOT use OMNI BRAND PENDIMETHALIN 3.3 EC with that specific liquid fertilizer.

Chemigation Instructions (for low volume micro sprinklers)
Output of low volume sprinkler = 4 to 50 gallons per hour (gph) per emitter. Point of application MUST be above ground.
The system must be properly calibrated (with water only) to ensure that the amount of OMNI BRAND PENDIMETHALIN 3.3 EC applied corresponds 
to the recommended rate. Apply OMNI BRAND PENDIMETHALIN 3.3 EC in 14 to% inches of water during the first sprinkler set (use at least 1 inch 
of water in the states of Texas, New Mexico and Oklahoma). Maintain agitation in the injection nurse tank to keep a uniform herbicide suspension 
during application. When application is complete, flush the system with water.
Uniform distribution of OMNI BRAND PENDIMETHALIN 3.3 EC-treated irrigation water is the sole responsibility of the applicator and is required to 
avoid crop injury, lack of herbicide effectiveness or illegal pesticide residues in the crop. If you have any questions about calibration, you should
contact state extension service specialists, equipment manufacturers, or other experts.

Irrigation system should run a sufficient amount of time prior to OMNI BRAND PENDIMETHALIN 3.3 EC injection to have all emitters functioning 
properly. After system is operating properly, length of injection should be such that at one period of time during the injection, the first and last 
emitters in the system contain OMNI BRAND PENDIMETHALIN 3.3 EC-treated water. Add OMNI BRAND PENDIMETHALIN 3.3 EC to the supply 
tank already filled with the volume of water required for the injection period. Maintain proper agitation in OMNI BRAND PENDIMETHALIN 3.3 EC 
injection tank. OMNI BRAND PENDIMETHALIN 3.3 EC should be mixed in clean water and injected down-line from filters. Following OMNI BRAND 
PENDIMETHALIN 3.3 EC injection, system should be flushed for a period of time sufficient to clear the line of OMNI BRAND PENDIMETHALIN 3.3 
EC. (If OMNI BRAND PENDIMETHALIN 3.3 EC application is made during a normal irrigation cycle, injection should be made during the last 
stage.)
Chemigation Calibration (for low volume micro sprinklers)
Calculation of use rate is based on wetted area around emitters - NOT on tree acres. To determine correct amount of OMNI BRAND 
PENDIMETHALIN 3.3 EC, use the following formula:
Treated area per each emitter = A
A = 3.14 X (radius x radius)
The area in square feet wet in each acre = B B = A x emitters/acre

Use Instructions and Precautions for Flooded Basin Irrigation
• OMNI BRAND PENDIMETHALIN 3.3 EC may be applied through flooded basin irrigation systems designed to uniformly distribute irrigation 
water along the soil surface. Solid set systems utilizing tall riser for overhead application are excluded.
• Follow all label recommendations for OMNI BRAND PENDIMETHALIN 3.3 EC regarding rates per acre, timing of application, and crop-specific 
restrictions and limitations.
• DO NOT connect an irrigation system used for pesticide application to a public water system unless the pesticide label-prescribed safety 
devices for public water systems are in place.
• A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall 
shut the system down and make necessary adjustments should the need arise.
• Helena Agri-Enterprises, LLC recommends that OMNI BRAND PENDIMETHALIN 3.3 EC is mixed with water at a 1:1 ratio in the injection nurse 
tank to assist with product flowability. Maintain agitation in the injection nurse tank to keep a uniform herbicide suspension during application. 
When application is complete, flush the system with water.
• Tail water (runoff water) from flood irrigation that contains OMNI BRAND PENDIMETHALIN 3.3 EC should be re-circulated and contained in the 
field of initial application or used only on adjacent tree or vine crops or alfalfa for which OMNI BRAND PENDIMETHALIN 3.3 EC is registered 
for this type of application.
Applications via Flooded Basin Irrigation Systems
OMNI BRAND PENDIMETHALIN 3.3 EC may be applied via flooded basin irrigation systems, but only to the following crops: nonbearing fruit and 
nut trees, nonbearing vineyards, and alfalfa grown for seed production.
Special Precautions for Chemigation
DO NOT apply when wind speed favors drift beyond the area intended for treatment.
DO NOT connect an irrigation system used for pesticide application to a public water system unless the pesticide label-prescribed safety 
devices for public water systems are in place.
A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall 
shut the system down and make necessary adjustments should the need arise.
The pesticide injection pipeline must contain a functional, automatic quick-closing check valve to prevent the flow of fluid back toward the 
injection pump. It must also contain a functional, normally closed solenoid-operated valve located on the intake side of the injection pump and 
connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically 
or manually shut down.
The sprinkler chemigation system must contain a functional check valve, vacuum relief valve, and low-pressure drain appropriately located on 
the irrigation pipeline to prevent water source contamination from backflow. In addition, systems must use a metering pump, such as a positive 
displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and 
capable of being fitted with a system interlock.
The sprinkler chemigation system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the 
water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the point where pesticide distribution 
is adversely affected.
The irrigation line or water pump must include a functional pressure switch that will stop the water pump motor when the water pressure 
decreases to the point where pesticide distribution is adversely affected.
Chemigation Systems Connected to Public Water Systems
• Public water system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service 
connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year.
• Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone backflow preventer (RPZ) or the 
functional equivalent in the water supply line upstream from the point of pesticide introduction. As an option to the RPZ, the water from the 
public water system should be discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break (air gap) 
between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe.
• All chemigation systems connected to public water systems must also follow restrictions listed in the preceding section titled Chemigation.

Managing Off-Target Movement
Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage.
Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 12
The applicator should be familiar with and take into account the information covered in the Spray Drift Reduction Advisory Information presented 
below.
Pressure - DO NOT exceed the nozzle manufacturer's recommended pressures. For many nozzle types, lower pressure produces larger droplets. 
When high flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream produces larger droplets than other orientations and is
recommended practice. Significant deflection from the horizontal will reduce droplet size and increase drift potential.
The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural field crops:
1. The distance of the outermost nozzles on the boom must not exceed 3/4 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.
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- or straight-stream nozzles oriented straight back produce the largest droplets and the lowest drift.
SPRAY DRIFT
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather-related factors 
determines the potential for spray drift. The applicator and grower are responsible for considering all these factors when making decisions. It is the 
responsibility of the applicator to avoid spray drift onto nontarget areas.
INFORMATION ON DROPLET SIZE
The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest droplets that 
provide sufficient coverage and control. Applying larger droplets reduces drift potential but will not prevent drift if applications are made improperly or 
under unfavorable environmental conditions (see WIND, TEMPERATURE AND HUMIDITY, and TEMPERATURE INVERSIONS).
CONTROLLING DROPLET SIZE
Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets.
Systems using a gravity-flow pesticide dispensing system must meter the pesticide in the water at the head of the field downstream of a 
hydraulic discontinuity, such as a drop structure or weir box, to decrease potential for water source contamination from backflow water. 
Systems utilizing a pressurized water and pesticide injection system must meet the following requirements:
I. The system must contain a functional check valve, vacuum-relief valve, and low-pressure drain appropriately located in the irrigation 
pipe to prevent water source contamination from backflow.
II. The pesticide injection pipeline must contain a functional automatic quick closing check valve to prevent flow of fluids back towards the 
injection pump.
III. The pesticide injection pipeline must also contain a functional, normally closed solenoid-operated valve located on the intake side of the 
injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation 
system is either automatically or manually shut down.
IV. The system must contain a functional interlocking control to automatically shut off the pesticide injection pump when the water pump 
stops.
V. The irrigation pipe or water pump must include a functional pressure switch, which will stop the pump motor when the water pressure 
decreases to the point where pesticide distribution is adversely affected.
VI. Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump), of effective design and 
constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
VII. Any alternative to the above safety devices must conform to the list of EPA-approved alternative devices.
Be sure to regularly measure the flow in the field to ensure the correct amount of OMNI BRAND PENDIMETHALIN 3.3 EC is being metered 
into the irrigation water and also regularly monitor to ensure that treated water is being uniformly distributed across the field. Flow rates through 
metering devices and distribution of OMNI BRAND PENDIMETHALIN 3.3 EC can vary with water temperature and speed of water flow across 
the field.
Uniform distribution of OMNI BRAND PENDIMETHALIN 3.3 EC-treated irrigation water is the sole responsibility of the applicator and is 
required to avoid crop injury, lack of herbicide effectiveness, or illegal pesticide residues in the crop.
If you have questions about calibration, you should contact state extension service specialists, equipment manufacturers or other experts.

Filename: Omni Brand Pendimethalin 3.3 EC (5905-AUU) 012821 CLN 13
When using tank mixtures or sequential applications with OMNI BRAND PENDIMETHALIN 3.3 EC, always read the companion product label(s) to 
determine the specific use rates by soil types, weed species, and weed or crop growth stage. In addition, follow all precautions and restrictions 
including state and local use restrictions that may apply to specific products. Always follow the most restrictive label.
Uses with Other Products (Tank Mixes)
If this product is used in combination with any other product except as specifically recommended in writing by Helena Agri-Enterprises, LLC, then 
Helena Agri-Enterprises, LLC shall have no liability for any loss, damage, or injury arising out of its use in any such combination not so specifically 
recommended. If used in combination recommended by Helena Agri-Enterprises, LLC, the liability of Helena Agri-Enterprises, LLC shall in no 
manner extend to any damage, loss, or injury not directly caused by the inclusion of the Helena Agri-Enterprises, LLC product in such combination 
use, and in any event shall be limited to return of the amount of the purchase price of the product. Always perform a mixing test to check the 
compatibility of OMNI BRAND PENDIMETHALIN 3.3 EC with all potential tank mix partners.
Tank Mixing Information
OMNI BRAND PENDIMETHALIN 3.3 EC may be applied in a tank mix or a sequential application with other herbicides registered for use in a given 
crop. Refer to the companion label for weeds controlled in addition to OMNI BRAND PENDIMETHALIN 3.3 EC alone.
Additives
Spray adjuvants have little or no influence on performance of OMNI BRAND PENDIMETHALIN 3.3 EC herbicide when applications are made prior 
to weed emergence. However, several tank mixes with OMNI BRAND PENDIMETHALIN 3.3 EC require adjuvants to improve burndown of emerged 
weeds. Therefore, surfactants, liquid fertilizer (28%, 30%, or 32% UAN (urea ammonium nitrate) or ammonium sulfate), or crop oil concentrate may 
be used with OMNI BRAND PENDIMETHALIN 3.3 EC tank mixes applied preplant, preemergence, or early postemergence to the crop. Follow the 
adjuvant recommendations on the tank mix partner's label.
When an adjuvant (or a specific adjuvant product, such as a drift control agent) is to be used with this product, the use of a Chemical Producers and 
Distributors Association (CPDA) certified adjuvant is recommended. The recommended adjuvants must contain ingredients accepted by the EPA.
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.
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.
APPLICATION HEIGHT
Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required for aircraft 
safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind.
SWATH ADJUSTMENT
When applications are made with a crosswind, the swath will be displaced 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 droplets, etc.).
SENSITIVE AREAS
This 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, or nontarget crops or plants) is minimal (e.g., when wind is blowing away from the sensitive areas).
TEMPERATURE INVERSIONS
Applications should not occur during a temperature inversion because drift potential is high. Temperature inversions restrict vertical air mixing, which 
causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light, variable winds 
common during inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on nights with 
limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence can be indicated by 
ground fog; however, if fog is not present, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke 
generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that 
moves upward and rapidly dissipates indicates good vertical air mixing.
WIND
Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet size and equipment type, determine drift 
potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential.
NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift.

Use Methods, Timings and Rates
Established Alfalfa Grown for Seed Production (defined as alfalfa planted in the fall or spring that has gone through a summer season of 
cutting/mowing):
Uniformly apply OMNI BRAND PENDIMETHALIN 3.3 EC at a broadcast rate of 1.2 to 4.8 quarts per acre prior to weed emergence in one of the 
following ways:
• Apply to dormant established alfalfa.
• Apply before alfalfa exceeds 10 inches in height after first mowing/beating.
• Once the alfalfa reaches 10 inches in height or if the alfalfa has been mowed/beaten two or more times, OMNI BRAND PENDIMETHALIN 3.3
EC must be applied with drop nozzles directing the spray so that there is little to no contact with the foliage.

OMNI BRAND PENDIMETHALIN 3.3 EC may be applied by ground, air or chemigation.

OMNI BRAND PENDIMETHALIN 3.3 EC or OMNI BRAND PENDIMETHALIN 3.3 EC tank mix combination treatments are most effective in
controlling weeds when adequate rainfall or overhead irrigation is received within 1 days after application. If cultivation is necessary because of soil 
crusting or weed germination, use shallow tillage and make certain com seeds are below the tilled area.
Additional Weeds Controlled: In addition to the weeds listed in Table 1, OMNI BRAND PENDIMETHALIN 3.3 EC will control the following weeds 
in corn with CULTI-SPRAY application: wild proso millet and shattercane.
Use Methods and Timings
Preemergence - Apply after planting but before weeds and crop emerge.
OMNI BRAND PENDIMETHALIN 3.3 EC maybe applied in conventional, minimum, or no-till as a preemergence, postemergence, or 
postemergence incorporated (CULTI-SPRAY) application in field corn.
OMNI BRAND PENDIMETHALIN 3.3 EC may be applied in conventional tillage as a preemergence or postemergence application in sweet com, 
seed corn, or popcorn.
In no-till systems, utilize a no-till planter that is capable of planting through crop residue. The use of no-till planters under conditions that do not allow 
good soil coverage of the corn seed can result in reduced crop stand or injury if OMNI BRAND PENDIMETHALIN 3.3 EC contacts the germinating 
corn seed. Check equipment to ensure good seed coverage.
DO NOT exceed 1.2 lbs ai per acre of atrazine, as specified on the atrazine label. Under situations of low rainfall or soil moisture when deep 
germinating weeds such as shattercane or field sandbur are anticipated, mechanical incorporation will provide best results. If cultivation is needed 
after application and incorporation of OMNI BRAND PENDIMETHALIN 3.3 EC, the depth of cut should be no deeper than the depth of cut used to 
incorporate.
Postemergence - Apply postemergence until field com is 30 inches tall (20 to 24 inches tall for pop, seed and sweet corn) or in the V8 growth 
stage, whichever is more restrictive. If the com canopy prevents applications from reaching the soil, use drop nozzles and apply as a directed spray.
Restrictions
• DO NOT exceed 4.8 quarts (4 lbs. a.i.) of OMNI BRAND PENDIMETHALIN 3.3 EC per acre in any one crop year.
• Follow all precautions and restrictions on the labels of all products applied in combination with OMNI BRAND PENDIMETHALIN 3.3 EC.
Always follow the most restrictive label.
• DO NOT apply OMNI BRAND PENDIMETHALIN 3.3 EC less than 50 days prior to alfalfa harvest for forage or hay.
• DO NOT apply OMNI BRAND PENDIMETHALIN 3.3 EC less than 90 days prior to alfalfa harvest for seed. 
Limitations
• Some stunting and chlorosis of the alfalfa may occur with postemergence applications.
• Applications made after the alfalfa exceeds 6 inches in height may result in poor weed control due to possible reduced spray 
coverage to the soil
CULTI-SPRAY - Apply OMNI BRAND PENDIMETHALIN 3.3 EC alone or OMNI BRAND PENDIMETHALIN 3.3 EC plus atrazine when field corn is 
at least 4 inches tall until last cultivation (layby). OMNI BRAND PENDIMETHALIN 3.3 EC plus atrazine must be applied before the field corn 
reaches 12 inches in height.
Regardless of tillage system, plant corn at least 1-1/2 inches deep and completely cover with soil.
In conventional tillage systems, plant into a seedbed that is firm and free of clods and trash. Use only where adequate tillage is practiced to provide 
good soil coverage of the corn seed.

Uniformly apply the recommended rate of OMNI BRAND PENDIMETHALIN 3.3 EC after rice planting and before rice and weed emergence 
(spiking). Apply after the rice seed has absorbed water and germinated and after the soil has been previously sealed over the seed by at least 1 inch 
of rainfall or by irrigation (flush). If the soil has not been sealed by rain or flush, apply when 80 percent of germinated seeds have a primary root 
(radicle) or shoot at least 1/2-inch long. If there is insufficient moisture, flushing is recommended before OMNI BRAND PENDIMETHALIN 3.3 EC 
application to supply moisture for root (radicle) initiation and for vigorous rice and weed growth.
If applied to soil prior to these conditions or to cracked soil, stand reduction or stunting of rice may occur. Under some conditions, use of gibberellic 
acid-treated seed, heavy rainfall after application, or flushing after application may result in herbicide injury to rice. Rice can overcome moderate 
injury with appropriate cultural practices.
Early Postemerqence - Apply OMNI BRAND PENDIMETHALIN 3.3 EC from crop emergence to the 6-inch stage of growth. DO NOT apply OMNI 
BRAND PENDIMETHALIN 13 EC postemergence if potatoes are under stress from cold/wet or hot/dry conditions or crop injury may occur.
OMNI BRAND PENDIMETHALIN 3.3 EC may be applied as a delayed preemergence application in drilled dry-seeded rice or as an early
postemergence application in dry-seeded rice. Treatments may be applied to conventional, reduced or minimum tillage, and no-till (stale seedbed) 
rice. The seedbed should be firm and free of clods and must be prepared to allow for good seed coverage. The use of a planter under conditions that 
do not allow good soil coverage of the rice seed can result in reduced stand or stunting if OMNI BRAND PENDIMETHALIN 3.3 EC contacts 
germinating rice seed.
Delayed Preemergence - Apply OMNI BRAND PENDIMETHALIN 3.3 EC alone or with tank mix partner for delayed preemergence weed control in 
grain-drilled, dry-seeded rice. Apply OMNI BRAND PENDIMETHALIN 3.3 EC alone or in tank mixture to levees after the levees are pulled and 
planted. Exposed seeds that come in contact with OMNI BRAND PENDIMETHALIN 3.3 EC may be injured. Apply only when growing conditions 
favor vigorous rice growth. The seedbed should have adequate moisture for seed germination. Not for use in California.
Additional Weeds Controlled: In addition to the weeds listed in Table 1, OMNI BRAND PENDIMETHALIN 3.3 EC will control the following weeds 
in rice: junglerice and sprangletop.
Restrictions
• DO NOT apply to sweet potatoes or yams.
• DO NOT apply preplant.
• DO NOT make more than one application of OMNI BRAND PENDIMETHALIN 3.3 EC per year.
Precautions
• Application of OMNI BRAND PENDIMETHALIN 3.3 EC on White Rose variety potatoes during or followed by cool and/or wet weather 
conditions may result in crop injury.
Due to the residual activity of OMNI BRAND PENDIMETHALIN 3.3 EC, this treatment may be applied if rice is too small to maintain a flood on the 
field for weed control. However, proper water management practices must be followed for normal rice growth and activity of OMNI BRAND
PENDIMETHALIN 3.3 EC.
Chemiqation Applications
OMNI BRAND PENDIMETHALIN 3.3 EC may be applied through sprinkler irrigation systems. Apply OMNI BRAND PENDIMETHALIN 3.3 EC

Early Postemerqence - Apply OMNI BRAND PENDIMETHALIN 3.3 EC as a tank mix partner. Base applications on weed and crop size guidelines 
of the tank mix partner. DO NOT apply to fields with standing water. If necessary, fields may be flushed prior to treatment to produce vigorous rice 
and weed growth. Since soil and weeds must be completely exposed to spray coverage, no flood water should be on the field at the time of 
application. Cloddy soil, standing water (puddles) at the time of application, or cracks in the soil that form after application may result in reduced 
weed control. Because of residual activity of OMNI BRAND PENDIMETHALIN 3.3 EC, this treatment may be applied if rice is too small to maintain a

Precautions
• In case of a crop failure due to weather conditions or disease following treatment with OMNI BRAND PENDIMETHALIN 3.3 EC alone or in 
a tank mixture, only drilled dry-seeded rice may be immediately replanted; however, the grower assumes all risks and consequences 
associated with replanting of rice because there is the potential for stand reduction or stunting. A10 percent increase in seeding rate is 
recommended. Replant seed below the herbicide layer because reduced stand or stunting may occur if OMNI BRAND PENDIMETHALIN 
3.3 EC contacts germinating rice seed.
