Dry weather following preemergence application of Bicep 4.SL or 
a tank mixture may reduce effectiveness. Cultivate if weeds 
develop in conventional tillage corn. 
Thoroughly clean sprayer prior to use. Do not use a sprayer 
contaminated with 2,4-D or other materials as crop damage or 
sprayer clogging may result. 
Note: (Bicep 4.SL Alone and in Tank Mixtures): Use ~nly on 
field corn. Do net use on sweet corn and popcorn. 
Mixing Instructions 
Shake well before using. Bicep 4.SL is a liquid that may be 
mixed with water or fluid fertilizer and applied as a spray. 
Bicep 4.SL may also be sprayed onto dry bulk granular fertilizer 
and appl1ed with the granular fertilizer. 
Dry Bulk Granular Fertilizers 
Many dry bulk granular fertilizers may be impregnated or coated 
with Bicep 4.SL and incorporated into the soil to controL weeds 
in corn. 
Labels, supplementary literature, and precautions regarding 
rates per acre, approved crops, soil texture, application, 
incorporation, c~op rotat'on and other directions must be 
followed for Bicep 4~.sL. 
All individual state regulations relating to dry bulk granular 
fertilizer blending, registration, labeling and application are 
the responsibility of the individual and/or co.pany selling the 
herbicide/fertilizer mixture. 
Apply 200-700 pounds per acre of dry granular fertilizer 
impregnated with Bicep 4.SL.

Prepare the qranular herbicide/fertilizer mixtures by usinq any 
closed drua, belt, ribbon, or other co..only used dry bulk 
fertilizer blender. Nozzles used to spray Bic~p 4.SL onto the 
fertilizer must be placed to provide uniform spray coverage. 
If thft herbicide/fertilizer .ixture is too wet, use a highly 
absorptive powder, such as Aqsorb.~raaul.s, Microcel E (Johns­
Manvill~ Products Corporation), diatomaceous earth or finely 
powdered clay, to obtain a dry free-flowing mixture. Add the 
absorptive powder separately and uniformly to the herbicide/ 
fertilizer mixture and blend to form a suitable free-flowing 
aixture. Generally, less than 2% by weight of absorptive powder 
will be needed. 
Calculate amounts of Bicep 4.SL by the following formula: 
2,000 
lbs. of fertilizer 
per acre 
x 
pts. of Bicep 4.SL 
per acre 
pts. of Bicep 4.SL 
== per ton of 
fertilizer 
For best results, apply this mixture lmiformly to soil with 
properly palibrated equipment iaaediately after blending, and 
incorporate according to directions. 
precaution: Do not use on crops where bedding occurs follc .~ 
~he herbicide/fertilizer application or injury may occur. 
Application in Water or Fluid Fertilizers 
Bicep 4.SL Alone: Fill the spray tank one-half to three-fourths 
full with water or fluid fertilizer, add the proper amount of 
Bicep 4.SL, then add the rest of the water or fluid fertilizer. 
Provide sufficient. agitation during mixing and application to 
maintain a uniform suspension. 
Tank Mixtures: Fill the spray tank one-half to thrte-four~h. 
full with water or fluid fertilizer, add t~e proper .. ount of 
Bicep 4.SL, then add AAtrex or Princep, Dual, Graaox,ne Extra or 
Roundup, and finally add the rest of the water or flutd ferti­
lizer. Provide sufficient agitation during mixing ana applica­
tion to maintain a uniform suspension. .

• t C~atibility Test: Check the co.patibility of Bicep 4.SL and 
t .ixtures in fluid fertilizer by .ixing proportionate quan-
titie. in a small container, as described below, before mixing 
i in the spray tank. Nitrogen solutions or complete fluid fertil­
izers .ay replace all or part of the water in the spray. Since 
liquid fertilizers can vary, even within the .... analy.i., 
always check compatibility each time before reuse. Be especi­
ally careful when using cO!flete suspension or fluid fertilizers 
as serious compatibility proble.s are more apt to occur. Com­
mercial application equipment may improv~ compatibility in some 
instances. The following test assumes a spray volume of 2S 
gals. per acre. For other spray volumes. make appropriate 
changes in the ingredients. Check compatibility using this 
procedure: 
1} Add 1 pint of fertilizer to each of 2 on~-quart jars with 
tight lids. 
2} To one of the jars add 1/4 tsp. or 1.2 milliliters of a 
compatibility agent approved for this use, such as Compex. 
or Unitee (1/4 tsp. is equivalent to 2 pts. per 100 gals. 
spray). Shake or st~r gently to mix. 
3) To both jars add the appropriate amount of herbicide(s}. 
If more than one herbicide is used, add them separately 
with dry herbicides first, flowables next, and emulsifiable 
concentrates last. After each addition, shake or stir 
gen~ly to thoroughly mix. The appropriate amount of herbi­
cides for this test follows: 
Dry herbicides: For each pound to be applied per acre, 
add 1.4 teaspoons to each jar. 
Liquid herbicides: Fo!;' eacl:, pint to be applied per acre 
add 0.5 teaspoon or 2.5 milliliters to 
each jar. 
4} After adding all ingredients, put lids on and tighten, and 
invert each jar ten times to mix. Let the mixtures stand 
15 minutes and.then look for separation, large flakes, 
precipitates, gels, heavy oily film on the jar, or other 
signs of incompatibility. Determine if the compatibility 
agent is needed in the spray mixture by comparing the two 
jars. If either mixture separates, but can be remixed 
readily, the mixture can be sprayed as long as good II.gita­
tion is used. If the .ixtures are incompatible, test the 
following methods of improving compaUbility: (A) slurry 
the dry herbicides(s} in water before addition, or (B) add 
1/2 of the compatibility agent to the f~rtilizer and the 
other 1/2 to the emulsifiable concentrate or flowable 
herbicide before addltion to the mixture. If still incom­
patible, do not use the mixture.

Application Procedures 
Ground Application: For unifora distribution, use fan-type 
nozzle.. Screens in nozzles and in suction and in-line 
strainers should be no finer than sO-.esh. Use a pump with 
capacity to (1) .aintain 35-40 psi at the nozzles, and (2) pro­
vide sufficient agitation in tank to keep .ixture in suspension. 
Unless otherwise specified, use a .inimum of 10 gals. of spray 
mixture per acre. Rinse sprayer thoroughly with clean water 
i .. ediately after use. 
For band applications, calculate amount to be applied per acre 
as follows: 
band width in inches X broadcast rate = amount needed 
row width in inches per acre per acre of field 
Aerial Application (for Bicep 4.SL alone): Use aerial applica­
tion only where broadcast applications are specified. Apply a 
minimum of 1 gal. of water fo~ each 1 gal. of this product 
applied per acre, but for rates below 1 gal./acre, ase in 
sufficient water to equal' 2 gals./acre of total spray. Avoid 
applications under conditions where uniform coverage cannot be 
obtained or where excessive spray drift may occur. In order to 
assure that spray will be controllable within the target area 
when used according to label directions, make applications at a 
maximum heiqht of 10 ft., using low drift nozzles at a maximum 
pressure~f 40 psi, and restrict application to periods when 
wind speed does not exceed 10 mph. To assure that spray will 
not adversely affect adjacent sensitive non-target plants, apply 
Bicep 4.sL by aircraft at a minimum upwind distance of 400 ft. 
from sensitive plants. 
Avoid application to humans or animals. FlagmE"n and loaders 
should avoid inhalation of spray mist and prolonged contact with 
skin, and should wash thoroughly before eating and at the end of 
each day's operation. , 
Within rate ranges in all tables on this label, use the lower 
rate on soil relat,ively coarse-textured or low in organic 
matter; use the higher rate on soil relatively fine-textured or 
high in organic matter.

Environmental Hazards 
Do not apply d!rectly to water or wetlands (swamps, bogs, 
marshe~ and potholes). Do not contaminate water by cleaning 
of equipment or disposal of wastes. This pesticide contains 
atrazine which has been shown to be toxic to aquatic 
invertebrates. Runoff and drift from treated areas may be 
hazardous to aquatic organisms in neighboring areas. 
Grou:"ld Water and Surface Water Advisory v' 
Bicep 4.SL contains both the active ingredients atrazine and 
metolachlor. 
Atrazine can travel (seep or leach) through soil and can 
enter ground wat~r which may be used as drinking water. 
Atrazine has been found in ground water. Users are advised 
not to apply atrazine to sand and loamy sand soils where the 
water table (ground water) is close to the surface and where 
these soils are very permeable, i.e., well-drained. Your 
local .gricul';ural agencies can provide further information 
on the type of soil in your are. and the location of 
ground water. 
Metolachlor has been identified in limited sampling of 
ground wAter and there is the possibility that it may leach 
through the soil to ground water, especially where soils are 
coarse and ground water is Ilear the surface. Following 
application and during rainfall events ~~at cause runoff, 
metolachlor may reach surface water bodies including 
streams, rivers and reservoirs.
