GENERAL INFORMATION 
BUCTRIL® + alrazlna Gal is lormulated as a mixture product of octanoic acid and heptanoic acid esters of bromoxynil containing 
the equivalent of 2.0 pounds of bromoxynil per gallon plus 4.0 pounds of atrazine per gallon. BUCTRIL® + alrazlna Gal is packaged 
in 5 pint water soluble bags. Each water soluble bag contains 1.25 Ib of bromoxyml active ingredient and 2.5 Ib of atrazine active 
ingredient. 
BUCTRIL® + atrazlna Gel is a selective postemergence hemicide for control of important broad leaf weeds in:esting corn (field and 
pop),and sorghum (grain and forage). Optimum weed control is obtained when BUCTRIL® + alrezlne Gal is applied to actively 
growing weed seedlings. BUCTRIL® + atrazlne Gal is primarily a contact herbicide, therefore tborough coverage of the weed 
seedlings is essential for optimum control. BUCTRIL® + alrazlna Gal has limited residual activity. However, dependent on weather 
conditions following application, subsequent flushes of weed~ may not be controlled by the inrtial treatment. 
Occasional transrtory leaf burn may occur. The temporary leaf burn is similar to that seen with liquid fertilizer. Because the activity of 
BUCTRIL® + alrazlna Gel is not systemic, recovery of the crop is generally rapid with no lasting effect. 
MIXING, LOADING AND HANDLING INSTRUCTIONS 
GENERAL HANDLING INSTRUCTIONS: Each BUCTRIL® GEL water soluble bag comes sealed in a clear plastic outer sleeve. Do 
not b;eak the seal until the time of use. To use, open the end of the outer sleeve by tearing along the printed solid black line. DQ not 
use a kn~e or other sharp object to break the seal. Once the outer protective sis eve is open, the water soluble bag inside can be 
dropped into the spray tank at the appropriate time without touching i'. 
BUCTRIL® + ATRAZINE GEL ALONE: Begin filling the spray tank with clean water, When bottom of spray tank is covered wrth 
water to a depth of 6-8 inches, add the recommended number of BUCTRIL ® GEL soluble bags, Avoid dropping the soluble bags into 
the tank in such a way that t:-e bags end up c~vering the recirculation and outlet holes, After adding bags, continue to fill tank wrth 
water. Allow 3-4 minutes aftar dropping bags Into the tank for bags to dissolve before starting agitation, Tank should be at 
least 112 full when agrtation is started. Continue adding water to tank to a~hieve the desired level. Maintain sufficient agrtation to 
ensure a un~orm spray mixture during application. 
BUCTRIL® + alrazlna Gal-TANK MIXTURES: Begin filling the spray tank with clean water, When bottom of spray tank is covered 
with water to a depth of 6·8 inches, add ~he recommended number of BUCTRIL ® GEL soluble bags. After adding bags, continue to 
fill tank with water. Allow 3-4 minutes after dropping bags Into the tank for bags to dissolve before starting agitation. Tank 
should be at least 1/2 full when agrtatlon is started. Add the recommended amount of wettable powder, soluble powder, flowable, EC 
or soluble liquid product to be tankmixed to the spray tank. Continue adding water to tank to achieve the desired level, while 
maintaining agitation. 
BUCTRIL® + EJlrazlna Gal-WITH SPRAY ADDITIVES: Begin filling the spray tank wrth clean water. ~hen bottom of spra~' ~pr~ I<; 
covered wrth water to a depth of 6-8 Inches, add the recommended number of BUCTRIL® + atrazlne Gel solub:e rngo. Afte( addin')

surfactant or crop oil concentrate. Continue adding water to tank to achieve the desired level. If BUCTRIL® + at,"8Zlna Gal I~ t'l be

HANDLING PRECAUTIONS 
Do not allow the empty outer sleeve or the tear-strip to fall into the spray tank as they are not water soluble and may clog the 
sprayer. 
Do not handle the inner bag wrth wet gloves as the bag will begin to dissolve on contact wrth even a small amount of water. 
Do not open the inner bags or aHempt to remove the gel from them. The gel is not designed to be re-measured or subdivider' 
The PVA bag should not be opened and partial bag not used for a tankmlx. 
The entire contems of the water soluble bag must be used. 
APPLICATION PROCEDURES 
BUCTRIL® + airazlne Gel can be applied to registered use areas by ground, and aerial application equipment. Do not apply this 
!,roduct throuJh any type of Irrigation system. 
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 spra~ volume and delivery system that will ensure thorough and unfform spray coverage. For optimum spray distribution and 
thorcugh coverage use 01 flat fan nozzles (maximum tip size BOOB) with a minimum spray pressure of 30 psi at the nozzle tips are 
recommended. Other nozzle types that produce course spray droplets may not provide adequate coverage of the weeds to ensure 
optimum control. Raindrop® nozzles are not recommended a:; weed control with BUCTRIL® + atrazlne Gel may be reduced. In 
general a minimum spray volume of 10 gallons per acre (GPA) is recommended for optimum spray coverage. A minimum of 5 GPA 
with a minimum spray pressure of 50 psi may be used with higher speed, low volume ground application rt ground terrain, crop and 
weed density allow effective spray distribution. When using higher speed equipment a maximum speed of 10 mph is suggested n 
field condrtions cause excessive boom movement during application and subsequent poor spray coverage. Ground applications 
~ade when dry, dusty field conditions exist may provide reduced weed control in wheel track areas. 
When weed infestations are heavy, use of higher spray volumes and spray pressure will be helpful in obtaining uniform weed 
coverage. When corn or grain sorghum are large enough to interfere with the spray pattern, drop nozzles should be used to obtain 
uniform weed coverage. Do not apply when winds are gusty or when other condrtions favor poor spray coverage andior off target 
spray movement. 
AERIAL APPLICATION 
Usa orffice discs, cores and nozzle types and arrangements that will provide for optimum spray distributiorr and maximum coverage. 
In general a minimum spray volume of 5 GPA and a maximum pressure of 40 psi are recommended. A minimum spray volume of 3 
GPA may be used ff crop canopy and weed density allow adequate spray cove'~ge at that gallonage. 
Do not apply during inversion condrtions, when winds are gusty or when other condrtions favor poor spray coverage andior off target 
spray movement. Off target spray movement can be minimized by increasing the spray volume per acre and not applying when 
winds exceed 10 mph. 
CULTIVATION 
When properly utilized, timely cunivations may aid overall weed control efforts as well as crop growth. However, cunivation BEFORE 
or DURING BUCTRIL® + atrazlne Gel applications may place target weeds under stress, resulting in erratic weed control. 
Whenever BUCTRIL® + atrazlns Gel is being utilized in an overall weed control program, plan to postpone any ant:clf.ated 
cunivations until 5·7 days after application to ensure best performance.
