GENERAL J:NP'ORHA'l'J:ON 
This product, applied alone or in tank mixtures, is recommended for the 
preernergence and postemergence contro-l of. many annual grasses and broadleaf 
weeds in soybeans and corn grown under 'NO-TILL or other minimum tillage 
practices~ This product will also provide reduced competition from certain 
emerged perennial weeds. 
MOJ:S'l'CRE CONDJ:'l'J:ONS 
Rainfall or sprinkler irrigation within 6 hours after application may reduce 
control of emerged weeds. . 
Moisture in the __ £orm of rainfall or irrigati_on is required after application 
to move this product into the weed germination zone for p-ree,mergence weed 
control. The amount of moisture required depends on the soil moisture content 
at the time of application, soil type, and plant residues. Performance is 
improved when Il3 tb 3/4 inch of moisture is received within one week after 
applicatiori and prior to. weed emergence~ High intensity or excessive rainfall 
or irrigation after applicaticn may reduce preemergence weed control cn coarse 
soils~ 
READ AND CAREFULLY OBSERVE PRECAUTIONARY STATEMENTS AND ALL OTHER INFORMATION 
APPEARING ON THE LABELING OF ALL PRODUCTS USED IN MIXTURES.

SO:tL TEX'I'tLRE 
Applicators should evaluate soil and weed conditions carefully to assure that 
they choose the lowest effective label rate.-
The recommended use rates of this product and the other herbicides labeled for 
use in tank mixtures with this' product generally vary with soil texture. 
Unless soil texture is specifically-named, rate tables throughout this label 
refer to only three soil texture'groups: COARSE, MEDIUM and FINE. The 
following is· ~- complete listing of soil textures included ·in each of these 
three soil t-exture groups: 
SOIL TEXTURE 
GROUP 
'SOIL 
TEXTURE 
s~nd, loamy sand, sandy loam 
loam, silt loam, silt, sandy clay loam 
COARSE 
MEDIUM 
FINE silty clay loam, clay loam, sandy clay, silty clay, clay 
Refer to the above table to determine the corresponding soil texture group for 
the soil to be treated. 
WEEDS,CONTROLLED 
When applied as directed under conditions described~ this product alone or in 
tank mixtures with other products lis-ted will_ control or reduce competition 
from the weeds indicated. Refer to the "DIRECTIONS FOR USE" section to 
determine rates for- each crop. 
Reduced control of emerged weeds may occur when weeds are under poor growing 
conditions such as from drought stress~ when application f-ollows recent mowing 
or when excessiv~ amounts o'f dust cover- the plants. 
NOTE: For additional information on weeds controlled by this product applied 
. alone or irf tank mixtures with other products in DOUBLE CROP systems, consult

Broadcast Trea.tment-Apply this product-- and labeled tank _mixture products in 10 
to 30 gallons-of wab~r, or 10· to 50: gallons of liquid nitrogen (28 percent or 
32 percent solutions only) per acre, before. during or after planting, but 
PRIOR TO CROP EMERGENCE. Application of this product in fluid fertili£er 
should only be used for treatment of annual weeds less than 6 inches tall. 
Spray coverage should be uniform_ and complete-~ Under conditions of dense 
stubble or plant residue or very high weed populations, higher rates within 
the recommended ranges may be needed for best results. 
DO NOT APPLY BY AIR. 
MIX ONLY WITH CLEAN WATER. 
Ammonium Su1fate-The addition of ammonium sulfate in the spray solution may 
increase the performance of Bronco and Bronco tank mixtures on emerged annual 
weeds under adverse gr_owing- conditions. When using amrn.onium sulfate, add 2 
percent dry ammonium sulfate by weight or. 17 pounds per 100 gallons of water. 
Ammonium sulfate shOUld be added to the water in the spray tank and completely 
dissolved prior to adding herbicide or surfactant. bo not. mix ammonium sulfate 
in fluid fertilizer -solutions. 
If .ammonium sulfate is· added directly to th,tspray tank, add slowly with 
agitation. Adding too qUickly may clog outlet 14,nes. Nozzle tip plugging may 
result from the use of low-quality ammonium sulfate. _To determine quality, 
perform a jar test by adding 1/3 cup of ammonium sulfate to 1 gallon of water 
and agitate for 1 minute. If undiSSOlved sed~ment is observed, pre-dissolve 
the ammonium sulfate in water and filter prior_ to addition to the spray tank . 
Following use of ammonium sulfate, thoroughly rinse- the spray system with 
clean water to reduce corrosion.
