USE INFORMATION 
BUCTRIL® is formulated as an emulsifiable concentrate of octanoic acid ester of bromoxynil containing the equivalent of 2 pounds of 
bromoxynil per gallon. 
BUCTRIL is a selective postemergence herbicide for control of im portant broadleaf weeds infesting corn (field and pop), sorghum (grain 
and forage), wheat, barley, oats, rye, triticale, alfalfa (seedl ing), flax, onions (dry bulb), garlic, mint (established pepper mint and 
spearmint), Conservation Reserve Program (CRP) areas, grasses gr own for seed or sod production, non-residential turfgrass, and non-
cropland and industrial sites. Optimum weed control is obtained whe n BUCTRIL is applied to actively growing weed seedlings. BUC TRIL 
is primarily a contact herbicide; therefore, thorough coverage of the weed seedlings is essential for optimum control. 
BUCTRIL has little residual activity. Therefore, subsequent fl ushes of weeds will not be controlled by the initial treatment. G enerally, 
crops that form a good canopy will help shade subsequent weed flushes. However, certain crops or short-straw varieties, for exa mple 
Yaccora Rojo wheat, may not develop the crop canopy fast enough to shade the subsequent flushes of weeds. 
Occasional transitory leaf burn may occur. The temporary leaf bu rn is similar to that seen with liquid fertilizer. Because the activity of 
BUCTRIL is not systemic, recovery of the crop is generally ra pid with no lasting effect. Frequency and amount of leaf burn may be 
greater when crops are stressed by abrasive winds, cool to cold evening temperatures or mechanical injury, such as that caused by hail,

sleet or insect feeding. To reduce the potential for temporary leaf burn, applications should be made to dry foliage in the rec ommended 
spray volumes per acre when weather conditions are not extreme. 
 
WEED RESISTANCE-MANAGEMENT 
For resistance management, please note that Buctril Herbicide contains a Group 6 herbicide. Any weed population may contain plants 
naturally resistant to Group 6 herbicide. The resistant individuals may dominate the weed population if these herbicides are used 
repeatedly in the same fields. Appropriate resistance-management strategies should be followed. 
To delay herbicide resistance take one or more of the following steps: 
x Rotate the use of Buctril Herbicide or other Group 6 herbicides within a growing season sequence or among growing seasons 
with different herbicide groups that control the same weeds in a field. 
x 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. 
x 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. 
x Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possibl e 
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. 
x 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. 
x 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. 
x For further information or to report suspected resistance co ntact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). You 
can also contact your pesticide distributor or university extension specialist to report resistance. 
MIXING, LOADING AND HANDLING INSTRUCTIONS 
2.5 Gallon Containers 
Special care must be taken in mixing and loading this product. Hands should be placed on the container in such a way as to avoi d 
possible drip or splash. Correct procedures for mixing and loading are provided in Bayer CropScience’s Educational Program. 
30 Gallon and Bulk Containers 
If you will handle a total of 60 gallons or more of this produc t per day, you must use a mechani cal transfer system for all mix ing and 
loading operations. If this product is packaged in a 30-gallon drum , you must use a mechanical transfer system, which terminate s in a 
drip-free hard coupling, which may be used only with a spray, or mix tank which has been fitted with a compatible coupling. If you do not 
presently own or have access to a mechanical transfer system with this type of coupling, contact your dealer for information on how to 
obtain such a system or to modify your present system. When using a mechanical transfer system, do not remove or disconnect the 
pump or probe from the container until the container has been empt ied and rinsed. The pump or probe system must be used to rins e the 
empty container and to transfer the rinsate directly to the mixing or spray tank. 
BUCTRIL ALONE: Fill the spray tank 1/2 to 3/4 full with clean water. Begi n agitation and add the specified amount of BUCTRIL. Add 
water to the spray tank to the desired level. Maintain sufficient agitation to ensure a uniform spray mixture during application. 
TANK MIXTURES: BUCTRIL can be tank-mixed with other pesticide products provided that these other products are registered for use 
on the crop/use site to be treated. The tank mix must be used in accordance with the more restrictive pesticide label limitatio ns and 
precautions. No label dosage rates may be exceeded. BUCTRIL cannot be mixed with any product containing a label prohibition against 
such mixing. To apply BUCTRIL in mixture with another product, fi ll the spray tank 1/2 to 3/4 full with clean water and begin a gitation. If 
tank mixing with wettable powder, soluble powder, flowable or dr y flowable products, add the pow der or flowable product first. After the 
other herbicide is thoroughly mixed with water, add the specified am ount of BUCTRIL and add water to the spray tank to the desi red 
level. If tank mixing with other product types, add the BUCTRIL first before adding the other product. Always mix one product i n water

thoroughly before adding another product or compatibility problems may occur. Never mix two products together without first mix ing in 
water. 
Maintain sufficient agitation while mixing and during application to ensure a uniform spray mixture. If spray mixture is allowe d to remain 
without agitation for short periods of time, be sure to agitate until uniformly mixed before application.

If tank mixing with products other than those listed above or wit hin each crop section, a compat ibility test is recommended to ensure 
satisfactory spray preparation. To test for compatibility, use a small container and mix a small amount (0.5 to 1 quart) of spr ay, combining 
all ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop, do not use th is mixture for 
spraying. Indications of incompatibility usually will appear within 5 to 15 minutes after mixing. To ensure maximum crop safety and weed 
control, follow all cautions and limitations on this label and the labels of products used in the tank mixture with BUCTRIL.

SPRAYABLE LIQUID FERTILIZERS AND SPRAY ADDITIVES 
BUCTRIL can be applied in combination with sprayable liquid ferti lizer or spray additives such as surfactants or crop oil conce ntrate. 
When tank mixing with liquid fertilizer always add the fertilizer to the spray tank first and agitate thoroughly before adding BUCTRIL. 
Always predetermine the compatibility with liquid fertilizer by mixing small proportional quantities in advance. Agitation must be 
maintained during filling and application operations to ensure that BUCTRIL is evenly mixed with the fertilizer. Leaf burn may occur when 
BUCTRIL is applied with liquid fertilizer, but new leaves are not adversely affected. 
CAUTION: Fertilizers and spray additives can in crease foliage leaf burn when applied with BUCTRIL . Do not apply fertilizers or spray 
additives with BUCTRIL if leaf burn is a major concern due to env ironmental conditions, crop or variety sensitivity to BUCTRIL. Do not 
apply BUCTRIL in combination with fertilizers or spray additives if restricted under the individual crop use directions.

GROUND APPLICATION 
Use a standard herbicide boom sprayer that provides uniform and accurate application. Sprayer should be equipped with screens no finer 
than 50 mesh in the nozzle tips and in-line strainers. 
Select a spray volume and delivery system that will ensure thorough and uniform spray coverage. For optimum spray, distribution and 
thorough coverage use of flat fan nozzles (maximum tip size 8008) with a spray pressure of 40-60 psi are recommended. Other noz zle 
types and lower spray pressures that produce coarse spray drop lets may not provide adequate coverage of the weeds to ensure 
optimum control. Raindrop
® nozzles and flood nozzles are not recommended as weed control with BUCTRIL may be reduced. 
In general, a spray volume of 10 to 20 gallons per acre (GPA) is recommended for optimum spray coverage. A minimum of 5 GPA wit h a 
minimum spray pressure of 50 psi and a maximum ground speed of 10 mph may be used with higher speed, low volume ground 
application if ground terrain, crop and weed density allow effective spray distribution. When using higher speed equipment, a m aximum 
ground speed of 10 mph is suggested if field conditions cause excessive boom movement during application which results in poor spray 
coverage. Ground applications made when dry, dusty field conditions exist may provide reduced weed control in wheel track areas . 
Applications using less than 10 gallons per acre may result in reduced weed control. 
When weed infestations are heavy, use of higher spray volumes and spray pressure will be helpful in obtaining uniform weed cove rage. 
When corn or grain sorghum are large enough to interfere with th e spray pattern, drop nozzles should be used to obtain uniform weed 
coverage. If you are unsure of the infestation level or size of crop, consult your local extension service. 
AERIAL APPLICATION 
Use orifice discs, cores and nozzle types and arrangements that will provide for optimum spray distribution and maximum coverag e. In 
general, a minimum spray volume of 5 GPA and a maximum pressure of 40 psi are recommended.

SPRINKLER IRRIGATION APPLICATION 
BUCTRIL Herbicide can be applied through sprinkler irrigation syst ems to wheat, barley, oats, rye and triticale, field corn, po pcorn, and 
grain sorghum, mint, grasses grown for seed or sod production, garlic, onions (dry bulb) and seedling alfalfa. 
 Apply BUCTRIL Herbicide through sprinkler systems including cent er pivot, lateral move, side (wheel) roll, solid set, or hand move 
irrigation systems only. If hand moved pipe is used for chemigation, the pipe must not be handled in any way until 24 hours aft er 
chemigation has been completed and residues have been flushed from the system. When applying by chemigation, no person may ente r 
the application site unless in an enclosed vehicle. Do not apply this product through any other type of irrigation system. 
SPECIFIC REQUIREMENTS FOR APPLICATION THROUGH AUTOMATED SPRINKLER IRRIGATION SYSTEM. 
1. The system must contain a functional check valve, vacuum re lief valve, and low-pressure drain appropriately located on the 
irrigation pipeline to prevent water source contamination from backflow. 
2. The pesticide injection pipeline must contain a functional, aut omatic, quick-closing check valve to prevent the flow of flui d back 
toward the injection pump. 
3. The pesticide injection pipeline must also contain a functiona l, normally closed, solenoid-operated valve located on the int ake side 
of the injection pump and connected to the system interlock to pr event fluid from being withdrawn from the supply tank when the 
irrigation system is either automatically or manually shut down. 
4. The system must contain functional interlocking controls to au tomatically shut off the pesticide injection pump when the water pump 
motor stops. 
5. The irrigation line or water pump must include a functional pressure switch, which will stop the water pump motor when the w ater 
pressure decreases to the point where pesticide distribution is adversely affected. 
6. 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. 
7. Do not apply when wind speed favors drift beyond the area intended for treatment. 
8. Agitation is recommended in the pesticide supply tank when applying the BUCTRIL Herbicide. 
9. BUCTRIL Herbicide should be applied continuously for the durati on of the water application with center pivot and continuous lateral 
move systems. Application of BUCTRIL Herbicide should be made during the last 30-45 minutes of the irrigation set with other 
overhead sprinkler systems. 
10. For best performance, set the sprinkler system to deliver approximately 0.5 inch or less of water per acre. 
11. Remove scale, pesticide residues, and other foreign matter from the supply tank and entire injector system. Flush with clean water. 
12. If BUCTRIL Herbicide is diluted in the supply tank, fill the ta nk with half of the water amount desired, add the BUCTRIL, a nd then 
add remaining water amount with agitation. Always dilute with at least 4 parts water to 1 part BUCTRIL. 
13. Start the sprinklers and then inject BUCTRIL Herbicide into the irrigation line. BUCTRIL should be injected with a positive 
displacement pump into the main line at least 8 feet ahead of a right angle turn to insure adequate mixing. Refer to the BUCTRI L 
Herbicide label for detailed information on application rates and timings. 
 
CHEMIGATION USER PRECAUTIONS 
Application of more than 0.5 inch/acre of irrigation water may result in decreased product performance on certain soils. 
Do not apply when conditions favor drift, when system connections or fittings leak, or when nozzles do not provide uniform distribution. 
Allow sufficient time for pesticide to be flushed through all the lines and nozzles before turning off irrigation water. 
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform distribution of treated water. 
Do not connect an irrigation system used for pesticide application to a public water system. 
If you have questions about calibration, you should contact Stat e Extension Service specialists, equipment manufacturers or oth er 
experts. 
A person knowledgeable of the chemigation system and responsible for its operations, or under the supervision of the responsibl e 
person, shall shut the system down and make necessary adjustments should the need arise. 
CULTIVATION 
When properly utilized, timely cultivations of row crops may ai d overall weed control efforts as well as crop growth. However, cultivation 
BEFORE or DURING BUCTRIL applications may place target weeds under stress, resulting in erratic weed control. Whenever BUCTRIL 
is being utilized in an overall weed control program, plan to postpone any anticipated cultivations until 5-7 days after application to ensure 
best performance.

SPRAY DRIFT MANAGEMENT 
 
Mandatory Spray Drift Management 
Aerial Applications 
x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, 
unless a greater application height is necessary for pilot safety. 
x Applicators are required to use a fine or coarser droplet size (ASABE S641). 
x Do not apply when wind speeds exceed 10 mph at the application site. 
x The boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of the rotor 
diameter for helicopters. 
x Applicators must use ½ swath displacement upwind at the downwind edge of the field. 
x Do not apply during temperature inversions. 
 
Ground Boom Applications 
x User must only apply with the release height recommended by the manufacturer, but no more than 4 feet 
above the ground or crop canopy. 
x Do not apply when wind speeds exceed 10 mph at the application site. 
x Do not apply during temperature inversions. 
 
SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
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. 
 
Controlling Droplet Size - Ground Boom 
x Volume - Increasing the spray volume so that larger drop lets are produced will reduce spray drift. Use the highest 
x practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher 
x flow rate. 
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and 
x droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce 
drift. 
 
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. 
 
Boom Height - Ground Boom 
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. 
 
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. 
 
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. 
 
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.

RESTRICTIONS AND PRECAUTIONS: Corn (Field and Pop) and Sorghum (Grain and Forage), and Sudangrass 
• BUCTRIL does not control grasses. Therefor e, it is recommended that a suitable grass control program be used to provide any 
required grass control. 
• Addition of a spray additive or mixture with liquid fertilizers may cause excessive crop leaf burn. 
• Seed corn producers should consult the respective seed corn company regarding tolerance of certain seed production inbred line s 
to BUCTRIL. 
• Do not apply BUCTRIL to postemergence to se ed corn inbreds or popcorn prior to the 3 leaf stage of crop growth as excessive crop 
leaf burn may occur. 
• Do not plant rotational crops within 30 days following BUCTRIL Herbicide application. 
• Do not cut crop for feed, fodder or graze within 45 days of application. 
• Do not enter or allow worker entry into treated areas duri ng the restricted-entry interval (REI) of 2 days for corn. 
• The total cumulative rate must not exceed 2 pints (0.5 pounds bromoxynil) per acre per season. 
• Postemergence application prior to the 3 leaf growth stage of corn or sorghum may result in increased crop leaf burn. 
• Tank mixtures with Accent ®/nonionic surfactant or Beacon®/nonionic surfactant may result in increased initial crop leaf burn. Use of 
crop oil concentrate, nitrogen fertilizer solution or other adjuvants in BUCTRIL + Accent ® or BUCTRIL + Beacon® tank mixtures may 
result in a further increase in crop leaf burn. 
• Special care must be taken when using BUCTRIL and Banvel ®, Clarity®, or 2, 4-D tank mixtures to avoid off target drift to sensitive 
crops. 
• Tank mixtures with 2, 4-D, Banvel ®, or Clarity® can cause stalk brittleness to field corn. Tank mixtures with 2, 4-D and Banvel®, can 
cause stalk brittleness to sorghum. Winds or cultivation may cause breakage while crop is brittle. 
• Follow all restrictions and precautions on the label of all products used in tank mixture with BUCTRIL. 
• Do not apply BUCTRIL at any rate to sorghum after the preboot stage of growth (growth stage 4) as severe crop injury; including 
loss of crop yield may result. 
• Do not apply the 2 pints/A rate of BUCTRIL to sorghum. 
• Do not apply the BUCTRIL + Pursuit® tank mix except to field corn hybrids known to possess resistance to Pursuit®, or severe crop

RESTRICTIONS AND PRECAUTIONS: Alfalfa (Seedling) 
• Crop leaf burn can occur following BUCTRIL application. Warm, humid conditions may enhance leaf burn. New crop growth will not 
be affected. Alfalfa yield should not be reduced although total biomass tonnage may decrease compared to a weedy field due to 
weed removal. 
• Do not apply when alfalfa is under moisture, temperature, inse ct, or disease stress or has been stressed by other pesticide 
carryover or application. 
• If combined with herbicides requiring oil adjuvants or surfactants, increased alfalfa injury will occur. 
• Do not cut for feed or graze spring treated alfalfa within 30 days following treatment. 
• Do not cut for feed or graze fall or winter treated al falfa until spring, at least 60 days following treatment. 
• Do not plant rotational crops within 30 days following BUCTRIL Herbicide application. 
• Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 2 days for alfalfa. 
• The total cumulative rate of BUCTRIL must not exceed 2 pints (0.5 pounds bromoxynil) per acre per season. 
• The use of Eptam
® preemergence may enhance crop leaf burn from postemergence application of BUCTRIL and should be 
considered prior to using BUCTRIL. 
• Follow all restrictions and precautions on the tank mixt ure product label when a BUCTRIL tank mixture is used. 
• Tank mixture with 2, 4-DB may result in unacceptable cr op leaf burn especially under warm, humid weather conditions. 
• BUCTRIL alone can be applied to seedling alfalfa that has been underseeded into small grains that include wheat, barley, oats, rye, 
and triticale. See application restrictions under the SMALL GRAINS SECTION. 
• Rainfall or overhead irrigation within 7 – 10 days following BUTYRAC® 200 application can cause unacceptable crop injury.

• Do not apply to mint growing under adverse conditions includi ng diseases, insects, nematodes, high salt content soil, drought, 
excessive moisture, winter damage, or other environmental stress. 
• Application of BUCTRIL to mint should not be made within two weeks of a Sinbar ® application or unacceptable crop injury may 
result. 
• Do not use in spring on newly established mint. Fall applications to spring planted mint should be acceptable if the crop is well 
established. 
• BUCTRIL can cause temporary stunting and discoloration of the mi nt particularly from the spring application. However, the injury 
symptoms are only temporary and have not caused yield reduction. 
• Use of BUCTRIL in combination with other products may increase temporary stunting and discoloration. 
• Do not harvest within 70 days following treatment. 
• Do not apply more than 6 pints (1.5 pounds bromoxynil) of BUCTRIL per acre to mint in a single growing season.

Preemergence 
1-1 1/2 pints/A 
 
Preemergence use is restricted to 
onions grown east of the Mississippi 
River only on muck soils containing 
greater than 10% organic matter. 
Apply at least 3 to 4 days prior to 
emergence. Rainfall or irrigation within 
2 days following preemergence 
applications or 3 days prior to crop 
emergence may result in 
unacceptable crop injury. 
Preemergence applications can be 
applied using either ground or aerial 
equipment. 
 
Apply BUCTRIL at 1 pint/A to control 
MOST SUSCEPTIBLE weeds and 
1 1/2 pints/A for SUSCEPTIBLE 
weeds. Weeds should not exceed the 
4 leaf stage, 2 inches in height or 1 
inch in diameter, whichever comes 
first
. 
 Postemergence 
1-1 1/2 pints/A 
Apply only to onions, which have 2 to 
5 true leaves. 
Use at least 50 -70 gallons of water 
per acre and apply by ground 
equipment or chemigation only . 
Water volume is important - 
CONCENTRATED SPRAYS KILL 
ONIONS
. Thorough and uniform 
coverage is necessary for good weed 
control. 
In onion -producing areas, certain 
environmental conditions reduce 
development of waxy coating on the 
onion leaves, thus increasing the 
possibility of injury
. Dry s oil, dry onion 
foliage, high light intensity, low 
humidity, and high temperatures tend 
to increase the waxy coating on onion 
leaves and thus reducing chances for 
injury
. It is essential that the soil and 
onion foliage be dry at the time of 
application. Hum idity should be low 
and dew should be off the plants. 
 
 
RESTRICTIONS AND PRECAUTIONS: Onions (dry bulb) 
• The sensitivity of onions to BUCTRIL varies with the variety and environmental conditions. Therefore, even if all the label directions 
are followed, BUCTRIL application still may cause injury to onions under certain circumstances. 
• Do not irrigate onions that have received a preemergence applic ation of BUCTRIL for 2 days following application or within 3 days of 
crop emergence. 
• Do not apply BUCTRIL preemergence to onio ns grown West of the Mississippi River. 
• Do not use BUCTRIL on onions grown under low light intensit y, in areas such as Oregon, west of the Cascades. 
• Do not treat onions damaged by sand, insects, or diseases. 
• Do not apply postemergence applications of BUCTRIL to onions with aerial equipment. 
• Do not add surfactant. 
• Do not apply more than 1 ½ pints (0.375 pounds bromoxynil) of BUCTRIL per acre per year. 
• Do not plant rotational crops within 30 days following BUCTRIL Herbicide application. 
• Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 2 days for onion.

leaks and spills, excess product or waste, and vandalism. Do not allow this product to contaminate water, foodstuffs, feed 
or seed by storage or disposal. 
PESTICIDE STORAGE: Store pesticides away from food, pet food, feed, seed, fertilizers, and veterinary supplies. Keep 
container closed to prevent spills and contamination. 
PESTICIDE DISPOSAL: To avoid wastes, use all material in this container, including rinsate, by application according to 
label directions. If wastes cannot be avoided, offer remaining product to a waste disposal facility or pesticide disposal 
program. Such programs are often run by state or local governments or by industry. All disposal must be in accordance 
with applicable federal, state and local regulations and procedures 
CONTAINER HANDLING AND DISPOSAL: 
[Container Handling and Disposal for Nonrefillable Containers] 
Nonrefillable container. 
For nonrefillable containers of 5-gallon capacity or less 
Do not reuse the container to hold materials other than pesticides or dilute pesticides (rinsate). After emptying and 
cleaning, it may be allowable to temporarily hold rinsate or other pesticide-related materials in the container. Contact your 
state regulatory agency to determine allowable practices in your state. 
Triple rinse or pressure rinse (or equivalent) the container promptly after emptying. 
Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds 
after the flow begins to drip. Fill the container ¼ full with water and recap. Shake for 10 seconds. Pour rinsate into 
application equipment or a mix-tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to 
drip. Repeat this procedure two more times. 
Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 
10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix-tank while rinsing, 
or collect rinsate for later use or disposal. Insert pressure rinsing nozzle in the side of the container and rinse at about 40 
PSI for at least 30 seconds. Drain for 10 seconds after the flow begins to drip. 
For nonrefillable containers of greater than 5-gallon capacity 
Do not reuse or refill this container. 
Triple rinse or pressure rinse (or equivalent) the container promptly after emptying. 
Triple rinse large nonrefillable containers NOT equipped with pumping systems as follows: Empty the remaining contents 
into application equipment or mix-tank. Fill the container ¼ full with water. Replace and tighten closures. Tip the container 
on its side and roll it back and forth for 30 seconds, ensuring at least one complete revolution. Stand the container on its 
end and tip it back and forth several times. Turn the container over onto its other end and tip it back and forth several 
times. Empty the rinsate into application equipment or mix-tank, or store rinsate for later use or disposal. Repeat this 
procedure two more times. 
Triple rinse large nonrefillable containers equipped with pumping systems as follows: Empty the remaining contents into 
application equipment or mix-tank. Fill the container about 10 percent full with water. Agitate vigorously or recirculate 
water with the pump for 2 minutes. Pour or pump rinsate into application equipment or rinsate collection system. Repeat 
this rinsing procedure two more times. 
Pressure rinse large containers as follows: Empty the remaining contents into application equipment or mix-tank. Place 
container so that it can drain directly into application equipment or mix-tank while rinsing, or collect rinsate for later use or 
disposal. Insert pressure rinsing nozzle through the opening of the container or directly into the side of the container and 
rinse at about 40 PSI for at least 30 seconds or until rinsate runs clear. Continue to drain for 10 seconds after the flow 
begins to drip. 
Once the nonrefillable container is properly rinsed, offer for recycling, if available. Some container manufacturers offer 
container recycling. See additional information regarding manufacturer recycling programs attached to the container, if 
available. If no recycling information is available on the container, contact your chemical dealer or Bayer CropScience at 
1-866-99BAYER (1-866-992-2937), or contact the Ag Container Recycling council (ACRC) at 1-877-952-2272 or at

responsibility of the person disposing of the container. Triple rinse or pressure rinse (or equivalent) the container promptly 
after emptying and before final disposal. 
To triple rinse the refillable container before final disposal, empty the remaining contents from the container into 
application equipment or mix-tank. Fill the container at least 10 percent full with water. Agitate vigorously or recirculate 
water with the pump for 2 minutes. Pour or pump rinsate into application equipment or rinsate collection system. Repeat 
this procedure two more times. 
To pressure rinse the refillable container before final disposal, empty the remaining contents from the container into 
application equipment or mix-tank. Position the container so that it can drain directly into application equipment or mix-
tank while rinsing, or collect rinsate for later use or disposal. Insert pressure rinsing nozzle through the opening of the 
container or directly into the side of the container and rinse all interior area at about 40 PSI for at least 30 seconds or until 
rinsate drains clear. 
 
Once the refillable container is properly rinsed, offer for recycling, if available. Some container manufacturers offer
