USE INFORMATION 
BUCTRIL® 4EC is formulated as an emulsifiable concentrate of octanoic acid and heptanoic acid esters of bromoxynil containing the 
equivalent of 4 pounds of bromoxynil per gallon. 
BUCTRIL 4EC is a selective postemergence herbicide for control of important broadleaf weeds infesting corn (field and pop), sor ghum 
(grain and forage), wheat, barley, oats, rye, triticale, al falfa (seedling), flax, onions, garlic, mint (established peppermint and spearmint), 
grasses grown for sod production, non-residential turfgrass, and non-cropland and industrial sites. Optimum weed control is obt ained 
when BUCTRIL 4EC is applied to actively growing weed seedlings. BUCTRIL 4EC is primarily a contact herbicide; therefore thorough 
coverage of the weed seedlings is essential for optimum control. 
BUCTRIL 4EC has little residual activity. Therefore, subsequent fl ushes of weeds will not be controlled by the initial treatmen t. 
Generally, crops that form a good canopy will help shade subsequent weed flushes. However, certain crops or short-straw varieties, for 
example 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 bur n is similar to that seen with liquid fertilizer. Because the activity of 
BUCTRIL 4EC is not systemic, recovery of the crop is generally rapid with no lasting effect. Frequency and amount of leaf burn may be 
greater when crops are stressed by abrasive winds, cool to cold ev ening temperatures or mechanical injury, such as that caused by 
hail, sleet or insect feeding. To reduce the potential for temporar y leaf burn, applications should be made to dry foliage in t he 
recommended spray volumes per acre when weather conditions are not extreme. 
WEED RESISTANCE MANAGEMENT 
For resistance management, BUCTRIL 4EC is a Group 6 herbicide. Any weed population may contain or develop plants naturally 
resistant to BUCTRIL 4EC and other Group 6 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. 
 
To delay herbicide resistance take one or more of the following steps: 
x Rotate the use of BUCTRIL 4EC 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. 
For further information or to report suspected resistance, contact 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 30 gallons or more of this produc t per day, you must use a mechanical transfer system for all mix ing and 
loading operations. If this product is packaged in a 30-gallon dr um, 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 4EC ALONE: Fill the spray tank 1/2 to 3/4 full with clean water. Begin agitation and add the specified amount of BUCTRIL ® 
4EC. Add water to the spray tank to the desired level. Maintain sufficient agitation to ensure a uniform spray mixture during application.

6 
 
TANK MIXTURES: BUCTRIL 4EC can be tank-mixed with other pesticide produ cts 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 l imitations 
and precautions. No label dosage rates may be exceeded. BUCTRI L 4EC cannot be mixed with any product containing a label 
prohibition against such mixing. Refer to the specific crop sect ion for rates and other restrictions. To apply BUCTRIL 4EC in m ixture 
with another product, fill the spray tank 1/2 to 3/4 full with clean water and begin agitation. If tankmixing with wettable pow der, soluble 
powder, flowable or dry flowable products, add the powder or flowable product first. After the other herbicide is thoroughly mi xed with 
water add the specified amount of BUCTRIL 4EC and add water to the spray tank to the desired level. If tankmixing with other pr oduct 
types, add the BUCTRIL 4EC first before adding the other produc t. Always mix one product in water thoroughly before adding anot her 
product or compatibility problems may occur. Never mix two products together without first mixing 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 withi n each crop section, a compatibility 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 this 
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 th is label and the labels of products used in the tank mixture with 
BUCTRIL® 4EC. 
 
SPRAYABLE LIQUID FERTILIZERS AND SPRAY ADDITIVES 
BUCTRIL 4EC can be applied in combination with sprayable liquid fe rtilizer or spray additives such as surfactants or crop oil 
concentrate. When tankmixing with liquid fertilizer always add th e fertilizer to the spray tank first and agitate thoroughly be fore adding 
BUCTRIL® 4EC. Always predetermine the compatibility with liquid fertilizer by mixing small proportional quantities in advance. Agitation 
must be maintained during filling and application operations to ens ure that BUCTRIL 4EC is evenly mixed with the fertilizer. Le af burn 
may occur when BUCTRIL 4EC is applied with liquid fertilizer, but new leaves are not adversely affected. 
CAUTION: Fertilizers and spray additives can incr ease foliage leaf burn when applied with BUCTRIL ® 4EC. Do not apply fertilizers or 
spray additives with BUCTRIL 4EC if leaf burn is a major concer n due to environmental conditions, crop or variety sensitivity t o 
BUCTRIL® 4EC. Do not apply BUCTRIL 4EC in combinat ion 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 n o 
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 dropl ets 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 4EC 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 spee d 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

8 
 
coverage. Ground applications made when dry, dusty field conditio ns 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 4EC Herbicide can be applied through sprinkler irrigation systems to wheat, barley, oats, rye and triticale, field corn, popcorn, 
and grain sorghum, mint, grasses grown for sod production, garlic, and seedling alfalfa. 
Apply BUCTRIL 4EC Herbicide through sprinkler systems including c enter pivot, lateral move, side (wheel) roll, solid set or han d move 
irrigation systems only. If hand moved pipe is used for chemigatio n, 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 
enter 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, au tomatic, 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 functional, normally closed, solenoid-operated valve located on the int ake 
side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank whe n 
the irrigation system is either automatically or manually shut down. 
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the wat er 
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 displa cement 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 4EC Herbicide. 
9. BUCTRIL 4EC Herbicide should be applied continuously for the duration of the water application with center pivot and continuous 
lateral move systems. Application of BUCTRIL 4EC Herbicide sh ould 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 4EC Herbicide is diluted in the supply tank, fill the tank with half of the water amount desired, add the BUCTRI L 4EC 
and then add remaining water amount with agitation. Always dilute with at least 4 parts water to 1 part BUCTRIL® 4EC. 
13. Start the sprinklers and then inject BUCTRIL 4EC Herbicide in to the irrigation line. BUCTRIL 4EC 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 t he 
BUCTRIL 4EC 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 responsibl e 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 aid overall weed control efforts as well as crop growth. However, cultivation 
BEFORE or DURING BUCTRIL 4EC applications may place target wee ds under stress, resulting in erratic weed control. Whenever 
BUCTRIL 4EC 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. 
 
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 
practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. 
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and 
droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the in tended 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

10 
 
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 4EC does not control grasses. Ther efore, 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® 4EC. 
• Do not apply BUCTRIL 4EC to postemergence to seed 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 day s following BUCTRIL 4EC Herbicide application. 
• Do not cut crop for feed, fodder or graze within 45 days of application. 
• The total cumulative rate must not exceed 1 pint/A per season (0.5 lbs. a.i./A/year). 
• 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 4EC + Accent® or BUCTRIL 4EC + Beacon® tank 
mixtures may result in a further increase in crop leaf burn. 
• Special care must be taken when using BUCTRIL 4EC 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® 4EC. 
• Do not apply BUCTRIL 4EC at any rate to sorghum after the pr eboot stage of growth (growth stage 4) as severe crop injury, 
including loss of crop yield may result. 
• Do not apply the 1 pint/A rate of BUCTRIL 4EC to sorghum. 
• Do not apply the BUCTRIL 4EC + Pursuit ® tankmix except to field corn hybrids known to possess resistance to Pursuit®, or severe 
crop injury may result.

• 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 4EC 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 4EC can cause temporar y stunting and discoloration of the mint particularly from the spring application. However the 
injury symptoms are only temporary and have not caused yield reduction. 
• Use of BUCTRIL 4EC in combination with other product s may increase temporary stunting and discoloration. 
• Do not harvest within 70 days following treatment.

Preemergence 
1/2-3/4 pint/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 4EC at 1/2 pint/A to 
control MOST SUSCEPTIBLE weeds and 
3/4 pint/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 
1/2-3/4 pint/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 soil, 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. Humidity should be low and 
dew should be off the plants. 
 
 
RESTRICTIONS AND PRECAUTIONS: Onions (Dry Bulb) 
• The sensitivity of onions to BUCTRIL 4EC varies with the va riety and environmental conditions. Therefore, even if all the label 
directions are followed, BUCTRIL 4EC application still may cause injury to onions under certain circumstances. 
• Do not irrigate onions that have received a preemergence applic ation of BUCTRIL 4EC for 2 days following application or within 3 
days of crop emergence. 
• Do not apply BUCTRIL 4EC preemergence to onions grown West of the Mississippi River. 
• Do not use BUCTRIL 4EC on onions grown under low light inte nsity, 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 4EC to onions with aerial equipment. 
• Do not add surfactant. 
• Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 2 days for onion. 
• Do not apply more than 3/4 pint of BUCTRIL 4EC per acre in a single growing season (0.375 lbs. a.i./ A/ year).
