FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS 
LABEL MAY RESULT IN POOR WEEP CONTROL. CROP INJURY. OR ILLEGAL 
RESIDUES. 
Bicep 4.5L is a selective herbicide recommended as a preplant 
surface-applied, preplant incorporated, preemergence, post­
emergence broadcast or postemergence-directed treatment for con­
trol of most annual grasses and broadleaf weeds in corn (field 
corn, silage corn, sweet corn, or popcorn) and as a preplant 
surface-applied, preplant incorporated, or preemergence treat­
ment for control of most annual grasses and broadleaf weeds in 
grain or forage sorghum provided the sorghum seed has been prop­
erly treated by the seed company with Concepe. This product may 
be tank mixed with Bladexe (4L, BOW, 90WDG), Duale formulations, 
AAtrex® 4L (BOW, Nine-O®), or Princepe 4L (SOW or Calibere 90) 
for weed control in conventional tillage corn. This product may 
also be tank mixed with either Gramoxone® Extra or Roundupe 
alone or in combination with AAtrex, Bladex, Dual or Princep, in 
minimum-tillage or no-tillage corn, or tank mixed with either 
Gramoxone Extra or Roundup, in minimum-tillage or no-tillage 
sorghum. 
Following many years of continuous use of atrazine (one of the 
ingredients in Bicep 4.5L), and products chemically related to 
atrazine, biotypes of some of the weeds listed on this label 
which are controlled by the atrazine component have been 
reported to develop resistance to this and chemically related 
herbicides. Where this is known or suspected and weeds con­
trolled by this product are expected to be present along with 
resistant biotypes, we recommend the use of Bicep 4.5L in 
combination or in sequence with registered herbicides which do 
not contain triazines. Consult with your State Agricultural 
Extension Service for specific recommendations. 
Precautions; II If sorghum seed is not properly pretreated with 
Concep. Bicep 4.SL will severely injure the crop. 21 Injury may 
occur to corn or sorghum following the use of Bicep 4.5L under 
abnormally high soil moisture conditions during early develop­
ment of the crop. 
Bicep 4.SL alone or in tank mixture with AAtrex, Bladex, Dual, 
or Princep may be applied preplant incorporated, preplant sur­
face, or preemergence on corn in water or fluid fertilizer. Bi­
cep 4.SL may be applied in tank mix combination with Gramoxone 
Extra or Roundup with or without the above herbicides preplant 
surface or preemergence to corn. Apply the early postemergence 
treatment on corn in water only. Bicep 4.5L alone may also be 
applied on sorghum preplant incorporated, preplant surface, or 
preemergence in water or in fluid fertilizer. 
Bicep 4.SL may be applied in water by aircraft. Applications in 
fluid fertilizer should be only by ground equipment .

To avoid spray drift, do not apply under windy conditions. 
Avoid spray overlap, as crop injury may result. 
Do not apply this product through any type of irrigation system. 
Dry weather following preemergence application of Bicep 4.SL or 
a tank mixture may reduce effectiveness. Cultivate if weeds 
develop in conventional tillage corn or sorghum. 
Observe all precautions and limitations on the label of each 
product used in tank mixtures. 
Thoroughly clean sprayer prior to use. 
contaminated with any other materials, 
clogging may result. 
Mixing Instructions 
Do not use a sprayer 
or crop damage or sprayer 
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 applied with the granular fertilizer. 
Dry Bulk Granular Fertilizers 
Many dry bulk granular fertilizers may be impregnated or coated 
with Bicep 4.SL and used to control weeds in corn or 
Concep-treated sorghum. 
When applying Bicep 4.SL with dry bulk granular fertilizers, 
follow all directions for use and precautions on the Bicep 4.SL 
label regarding target crops, rates per acre, soil texture, 
application methods, ~nd rotational crops. 
All individual state regulations relating to dry bulk granular 
fertilizer blending, registration, labeling, and application are 
the responsibility of the individual and/or company selling the 
herbicide/fertilizer mixture. 
Prepare the herbicide/fertilizer mixture by using any closed 
drum, belt, ribbon, or other commonly used dry bulk fertilizer 
blender. Nozzles used to spray Bicep 4.SL onto the fertilizer 
must be placed to provide uniform spray coverage. 
If the herbiciaq/fertilizer mixture is too wet, use a highly 
absorptive pow a r, such as Microcel E (Johns-Manville Produ~ts 
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 mixture. Generally, less 
than 2% by weight of absorptive powder will be needed .

Calculate the amount of Bicep 4.SL to be used by the following: 
2.000 
Ibs. of 
fertilizer 
per acre 
x 
qts. of Bicep 4.SL 
per acre = 
qts. of Bicep 4.SL 
per ton of 
fertilizer 
Precautions: To avoid potential for explosion. (1) po not 
impregnate Bicep 4.SL on ammonium nitrate. potassium nitrate. or 
sodium nitrate either alone or in blends with other fertilizers. 
(2) po not combine Bicep 4.SL with a single supe~osphate 
(0-20-0) or treble supe~hosphate /0-46-0). (3) po not use Bi­
cep 4.SL on straight limestone. since absorption will not be 
achieved. Fertilizer blends containing limestone can be impreg­
nated. 
Application 
Apply 200-700 pounds of the herbicide/fertilizer mixture per 
acre. For best results, apply the mixture uniformly to .. the soil 
with properly calibrated equipment immediately after blending. 
Uniform application of the herbicide/fertilizer mixture is 
essential in order to prevent possible crop injury or injury to 
subsequent rotational crops. Non-uniform application may also 
result in unsatisfactory weed control. In areas where conven­
tional tillage is practiced, a shallow incorporation of the mix­
ture into the soil is recommended to obtain satisfactory weed 
control. On fine or medium-textured soils in areas where soil 
incorporation is not planned, i.e., reduced tillage situations 
or in some conventional till situations, make applications 
approximately 30 days before planting to allow moisture to move 
the herbicide/fertilizer mixture into the soil. On coarse­
textured soils, make applications approximately 14 days prior to 
planting. 
Precautions: (1) To help avoid rotational crop injury. make 
applications as early as possible. since Bicep 4.SL impregnated 
onto dry bulk granular fertilizers can be expected to last 
longer in the soil than when Bicep 4.SL is applied as a spray in 
water or fluid fertilizer. (2) po not use on crops where bed­
ding occurs. or crop injury may occur. 
application in Water or Fluid Fertilizers 
Bicep 4.SL Alone: Fill the spray tank one~half·tn-Lhree~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. 
~ank Mixtures: 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 AAtrex, Banvel, linuron, or Princep; next

-8-
add Dual; then Gramoxone Extra or Roundup, depending on the tank 
mix combination desired; and finally add the rest of the water 
or fluid fertilizer. When Bladex is used in the tank mixture, 
add it before Bicep 4.5L unless otherwise specified. (See 
Bladex section under Bicep 4.5L Combinations-Corn for further 
mixing instructions.) Provide sufficient agitation during mixing 
and application to maintain a uniform suspension. 
Compatibility Test: Check the compatibility of Bicep 4. 5L and 
tank mixtures in fluid fertilizer by mixing proportionate quan­
tities in a small container, as described below, before mixing 
in the spray tank. Nitrogen solutions or complete fluid fertil­
izers may replace all or part of the water in the spray. Since 
liquid fertilizers can vary, even within the same analysis, 
always check compatibility each time before reuse. Be espe­
cially careful when using complete suspension or fluid 
fertilizers as serious compatibility problems are more apt to 
occur. Commercial application equipment may improve compatibil­
ity in some instances. The following test assumes a spray vol­
ume of 25 gals. per acre. For other spray volumes, make appro­
priate changes in the ingredients. Check compatibility using 
this procedure: 
1) Add 1 pint of fertilizer to each of 2 one-quart jars with 
tight lids. 
2) To Qfie of the jars add 1/4 tsp. or 1.2 milliliters of a 
compatibility agent approved for this use, such as Compex® 
or Unite® (1/4 tsp. is equivalent to 2 pts. per 100 gals. 
spray). Shake or stir 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
tly to thoroughly mix. The appropriate amount of herbi­
cides for this test follows: 
Dry herbicides: 
Liquid herbicides: 
For each pound to be applied per acre 
add 1.4 teaspoons to each jar. 
For each 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, pre­
cipitates, 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 agitation is

-9- II i 3S 
used. If the mixtures are incompatible, test the following 
methods of improving compatibility: (A) slurry the dry 
hert><.cide (s) in water before addition, or (B) add 1/2 of 
the compatibility agent to the fertilizer and the other 1/2 
to the emulsifiable concentrate or flowable herbicide 
before addition to the mixture. If still incompatible, do 
not use the mixture. 
Application Procedu~ 
Ground Application: Use sprayers that provide accurate and uni­
form application. Screens in nozzles and in suction and in-line 
strainers should be no finer than 50-mesh. Use a pump with 
capacity to (1) maintain 35-40 psi at the nozzles, and (~) pro­
vide sufficient agitation in tank to keep mixture in suspension. 
Unless otherwise specified, use a minimum of 10 gals. of spray 
mixture per acre. Rinse sprayer thoroughly with clean water 
immediately after use. 
For band applications, calculate amount to be applied per acre 
as follows: 
band width in inches 
row width in inches 
broadcast rate amount needed 
X per acre = per acre of 
field 
Aerial Application (for Bicep 4.SL alone): Use aerial applica­
tion only where broadcast ~pplications are specified. Apply a 
minimum of 1 gal. of water for each 1 gal. of this product 
applied per acre, but for rates below 1 gal./acre, use in suffi­
cient water to equal 2 gals./acre of total spray. Avoid appli­
cations 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 height of 10 ft., using low drift nozzles at a maximum 
pressure of 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 nontarget plants, apply 
Bicep 4.SL by aircraft at a minimum upwind distance of 400 ft. 
from sensitive plants. 
Avoid application to humans or animals. Flagmen and loaders 
should avoid inhalation of spray mist and prolonged contact with 
skin. 
Within rate ranges in all tables on this label, use the lower 
rate on soil I'elatively coarse-textured or low in organic mat­
ter; use the higher rate on soil relatively fine-textured or 
high in organic matter.

*Control of these weeds can be erratic especially under dry 
weather conditions. Control escaped weeds with cultivation or 
application of an appropriate EPA-registered postemergence 
herbicide. On fin~-textured soils, only partial control can 
be expected. 
**Control may be improved by following these suggested proce­
dures: 
1) Thoroughly till moist soil to de~troy germinating and 
emerged weeds. If Bicep 4.SL is to be applied preplant 
incorporated, this tillage may be used to incorporate Bicep 
4.SL if uniform 2 inch incorporation is achieved as recom­
mended under Application Procedures. 
2) Plant crop into moist soil iromediate1y after till~. If 
Bicep 4.SL is to be used preemergence, apply at planting or 
immediately after planting. 
3) If available, sprinkler irrigate within 2 days after appli­
cation. Apply 1/2-1 inch of water. Use lower water volume 
(1/2 inch) on coarse-textured soils. Also, refer to the 
section on Center Pivot Irrigation Application for this 
method of applying Bicep 4.SL. 
0"

-11- 13~ 35 
4) If irrigation is not possible and rain does not occur with­
in 2 days after planting and application, weed control may 
be decreased. Under these conditions, a uniform, shallow 
cUltivation is recommended as soon as weeds emerge. 
Bicep 4.5L Rate Limitations - Corn and Sorghum 
*Where there are state/local requirements regarding atrazine use 
(including lower ~aximum rates and/or greater setbacks) which 
are different from the label, the more restrictive/protective 
requirements must be followed. Certain states have established 
rate limitations within specific geographical areas. Consult 
your state lead pesticide control agency for additional informa­
tion. It is a violation of this label to deviate from state use 
regulations. 
Note: For purposes of calculating total atrazine active ingre­
dient applied, Bicep 4.5L contains 2.0 lbs. ai per gal. (0.5 lb. 
ai per qt.). 
FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE 
On Highly Erodible Soils (as defined by SCSI 
• If conservation tillage is practiced, leaving at least 30% 
of the soil covered with plant residues at planting, apply 
4 qtS./A as a broadcast spray. Refer to "B" in tables 
following. 
If the soil coverage with plant residue is less than 30% at 
planting, a maximum of 3.2 qtS./A may be applied. Refer to 
"A" in tables following. 
• On Soils Not Highly Erodible 
Apply a maximum of 4 qts./A as a broadcast spray. Refer to 
"B" in tables following. 
FOR POSTEMERGENCE APPLICATION TO CORN 
If no atrazine was applied prior to corn emergence, apply a 
maximum of 4 qts./A broadcast. If a postgmergence treatment 
is required following an earlier herbicide application, the 
total atrazine applied may not exceed 2.5 lbs. active 
ingredient (5 qts. of Bicep 4.5L) per acre per calendar year. 
Application Timings 
Preplant Surface Applied (Corn): Use on medium- and fine­
textured soils with minimum-tillage or no-tillage systems in CO, 
lA, IN, IL, KS, KY, MN, MO, MT, NO, NE, SO, TN, WI, and WY . 
.. ,

-12-
Apply 2/3 the recommended rate of Bicep 4.SL (3.2-4 qts./A o~ 
medium soils and 4 qts. on fine soils) as a split treatment 
30-45 days before planting and the remainddr at planting. 
Applications made less than 30 days prior to planting may be as 
either a split or single treatment. Use the lower rate for 
light expected weed infestations and the higher rate for heavy 
expected weed infestations. On coars.-textured soils, apply 3.2 
qts./A not more than 2 weeks prior to planting. The above pro­
cedure also may be followed if AAtrex or Dual BE or Princep is 
used in tank mixtures with Bicep 4.SL. If weeds are present at 
the time of treatment, apply in a tank mixture combination with 
a contact herbicide (for example, Gramoxone Extra or Roundup) • 
Observe directions for use, precautions, and restrictions on the 
label of the contact herbicide. 
On medium and fine-textured soils with minimum or no-tillage 
systems in DE, MD, MI, NY, OH, PA, VA, and WV, preplant surface 
applications may be applied following the directions for use 
above. If the amount of rainfall results in unsatisfactory 
length of weed control following the earlier treatment, a post­
emergence application of an appropriately labeled broadleaf 
and/or grass weed herbicide may be used, i.e., AAtrex, 
Basagran®, 2,4-0, Banvel®, bromoxynil (Brominal® or Buctril®) . 
If the postemergence treatment includes the herbicide used pre­
plant surface-applied, do not exceed the labeled rate for corn 
on a given soil texture. Observe all directions for use, pre­
cautions and limitations on the label of the post emergent herbi­
cide. 
Note: To the extent possible, do not move treated soil out of 
the row or move untreated soil to the surface during 
planting, or weed control will be diminished. 
Preplant Surface-IJplied (Sorghum-Seed Treated with Concep) : 
For minimum-tillage and no-tillage systems only, Bicep 4.SL may 
be applied up to 45 days before planting grain sorghum in IL, 
lA, eastern KS, MO, NE, and SO. Use only split applications for 
treatments made 30 to 45 days before planting with 2/3 the rec­
ommended rate applied initially and the remaining 1/3 at plant­
ing. On medium soils with greater than 1.5% organic matter, and 
on fine soils with less than 1.5% organic matter, apply 3.2-3.6 
qts./A of Bicep 4.SL; on fine soils with greater than 1.5% 
organic matter, apply 3.6-4 qts./A of Bicep 4.SL. Applications 
made less than 30 days prior to planting may be as either a 
split or a single application. 
If weeds are present at the time of treatment, apply in a tank 
mixture combination with a contact herbicide (for example, Gra­
moxone Extra or Roundup). Observe directions for use, precau­
tions, and restrictions on the label of the contact herbicide. 
Under dry conditions, irrigation after application is recom­
mended to move Bicep 4.SL into the soil. Use of low rates on 
fine soils may result in reduced control of certain broadleaf 
weeds. 
..'

-13-
Note: To the extent possible, do not move treated soil out of 
the row or move untreated soil to the surface during planting, 
or weed control will be diminished. Do not use on coarse soils. 
Do not use on medium soils with less than 1.5% organic matter. 
Preplant Incorporated or Preemergence (Corn or Sorghum-Seed 
Treated with Concep): Apply Bicep 4.5J. preplant incorporated or 
preemergence using the appropriate rates from Table 1 for corn, 
or from Table 2 for sorghum. 
Preplant Incorporated: Apply to the soil and incorporate into 
the top 2 inches of the soil within 14 days prior to planting 
uSing a finishing disk harrow, rolling cultivator, or similar 
implement capable of providing uniform 2-inch incorporation. 
Use preplant incorporated if furrow irrigation is used or when a 
period of dry weather after application is expected. If crop is 
to be planted on beds, apply and incorporate after bed forma­

Rotational Crops: (1) If treated crop is lost due to poor ger­
mination, hail, flood, insects, etc., corn may be replanted 
immediately or sorghum may ~e replanted immediately provided the 
seed has been properly treated with Concep. Do not make a sec­
ond broadcast application. If the original application was 
banded and the second crop is planted in the untreated row 
middles, a second banded treatment may be applied. (2) Corn, 
sorghum, soybeans, cotton, or peanuts may be plan~ed the spring 
following treatment. Do not graze or feed forage or fodder from 
cotton to livestock or illegal residues may result. Injury may 
occur to soybeans planted the year following application on 
soils having a calcareous surface layer, including, but not lim­
ited to those found in north-central and northwest IA; 
south-central, western and southwest MN; northeast NE; NO and 
eastern SO. (3) If applied after June 10, do not rotate with 
crops other than corn or sorghum the next year, or crop injury 
may occur. (4) In the High Plains and Intermountain areas of 
the West where rainfall is sparse and erratic or where irriga­
tion is required, use only when corn or sorghum is to be planted 
the following year, or a crop of untreated corn or sorghum is to 
p~ecede other rotational crops. (5) Small grains may be planted 
15 months following treatment. (6) All other crops may be 
planted 18 months after application.

AAtrex (4L. BOW. or Nine-O): Add up to 1 qt. of AAtrex 4L (1.25 
Ibs. BOW or 1.1 Ibs. Nine-O) per acre to the rate of Bicep 4.5L 
recommended in Table 1 in the southeastern U.S. where high rain­
fall can shorten the duration of control of broadleaf weeds, and 
in all areas where heavy infestations of cocklebur, morning­
glory, velvetleaf, or other broadleaf weeds claimed are 
expected. 
Dual: Add up to 1/2 pt. of Dual per acre to the rate of Bicep 
4.5L recommended in Table 1 when heavy infestations of yellow 
nutsedge, sandbur, or seedling johnsongrass are expected. 
Princep (4L. BOW. or Caliber 90): Add up to 1 qt. of Princep 4L 
(1.25 Ibs. 80W or 1.1 Ibs. Caliber 90) per acre to the rate of 
Bicep 4.5L recommended in Table 1 where heavy infestations of 
crabgrass or fall panicum are expected or additional control of 
certain broadleafs is desired. 
Bladex (4L. 80W~ or 90WDG) [Field Corn and Silage Corn Only]: 
Add up to 2 qts. of B1adex 4L (2.5 1bs. 80W or 2.2 1bs. 90WDG) 
per acre. When Bladex is added, the rate of Bicep 4.5L sug­
gested in Table 1 should be reduced by not more than 25% for a 
given soil texture in the Clarion-Nicol let-Webster soil associa­
tion in northern IA and southern MN, or in other areas where 
soybean rotational concerns exist. 
Note: Check the compatibility ,:,f Bicep 4.5L tank mixtures with 
Bladex before mixing in spray tank by using the procedure

-20-
described under Application in Water or Fluid Fertilizers. 
Always use Unite (or an equivalent compatibility agent) at 
2 pts./I00 gals. when using Bladex BOW or Bladex 90WDG in tank 
mixtures with Bicep 4.SL. Compatibility testing is especially 
critical when using Bladex BOW or Bladex 90WDG combinations.

less of which Bladex formulation is used. 
Tank Mixtures of Bicep 4.SL Alone or Bicep 4.SL plus AAtrex. 
Bladex. Dual. or Princep. with Gramoxone Extra or Roundup for 
Minimum-Tillage or NO-Tillage Systems 
In minimum-tillage or no-tillage systems where corn is planted 
directly into a cover crop, stale seedbed, established sod, or 
previous crop residues, the contact he=bicides Gramoxone Extra 
or Roundup should be tank mixed with Bicep 4.SL alone or with 
Bicep 4.5L plus AAtrex, Bladex, Dual, or Princep. When used as 
directed, the Gramoxone Extra portion of the tank mixture con­
crols most emerged annual weeds and suppresses many perennial 
weeds. Roundup combinations will control emerged annual and 
perennial weeds when applied as directed on the Roundup label. 
The Bicep 4.SL portion of the tank mixture provides preemergence 
control of the weeds listed on this label in the Bicep 4.5L 
Alone section for corn. The addition of AAtrex, Bladex, Dual, 
or Princep offers the advantage indicated for each under 
Conventional Tillage above. 
Application: Apply before, during, or after planting but before 
corn emerges, at the appropriate rate in Table 5. Up to 1 qt. 
of AAtrex 4L (1.25 Ibs. BOW or 1.1 lbs. Nine-O), or 2 qts. of 
Bladex 4L (2.5 Ibs. BOW or 2.2 Ibs. 90WDG), or 1/2 pt. of Dual, 
or 1 qt. of Princep 4L (1.25 Ibs. BOW or 1.1 Ibs. Caliber 90) 
per acre may be added to the rate of Bicep 4.5L recommended in 
Table 5. Add Gramoxone Extra or Roundup at the following broad­
cast rates: 
Gramoxone Extra: 1.5-2.0, 2.0-2.5, 2.5-3.0 pts. per acre to 
1-3 inches, 3-6 inche~, or 6-inch tall weeds, respectively. 
Apply surfactant at 1 or 2 pts. per 100 gals. of spray mix­
ture with 75% or greater or 50-74% non ionic active ingredi­
ent, respectively. This treatment will not control weeds 
taller than 6 inches. 
Roundup: 1.5 qts. per acre for control of existing annual 
weeds, or 2-4 qts. per acre for existing perennial weeds. 
See the Roundup label for weeds controlled and recommended 
rates for specific weeds .

Tank Mixtures of Bicep 4.5L Alone or Bicep 4.5L plus AAtrex or 
Bladex. with 2.4-0 or 2.4-p plus Banvel for Minimum-Tillage or 
No-Tillage Systems 
In minimum-tillage or no-tillage systems where corn is planted 
directly into a cover crop, stale seedbed, established sod, or 
previous crop residues, Bicep 4.5L may be applied in combination 
with AAtrex or Bladex. When used as directed, the Bicep 4.5L 
portion of the tank mixture provides preemergence control of the 
weeds listed on this label in the Bicep 4.5L Alone section for 
corn. The addition of AAtrex or Bladex offers the advantage 
indicated for each under Conventional Tillage above. 
Application: Apply Bicep 4.5L before, during, or after planting 
but before corn emerges, at the appropriate rate in Table 5. Up 
to 1 qt. of AAtrex 4L (1.25 lbs. BOW or 1.1 lbs. Nine-O) or 2 
qts. of Bladex 4L (2.5 lbs. BOW or 2.2 lbs. 90WDG) per acre may 
be added to the rate of Bicep 4.5L recommended in Table 5. 
Where heavy crop residues exist, add an appropriately-labeled 
2,4-0 am1ne or low volatile ester to the spray tank last and 
apply in a minimum of 25 gals. of carrier/A. 
As carriers, nitrogen solutions and complete liquid fertilizers, 
applied before corn emergence, enhance burndown of existing 
weeds, and therefore are recommended instead of water. Add 
X-77® surfactant at 1-2 qts./IOO gals. of diluted spray, or an­
other surfactant cleared for use on growing crops at its recom­
mended rate. Apply before weeds exceed 3 inches in height. If 
alfalfa is present, add Banvel to the spray mixture at 
0.33-0.5 pt./A and apply before alfalfa exceeds 6 inches in 
height. 
For fields with existing sod grasses (e.g., bromegrass, orchard­
grass, rye or timothy), when existing weeds exceed 3 inches in 
height or when very dry conditions exist, add Gramoxone Extra at 
the rate of 2.5 pts./A in place of or in addition to 2,4-0 as 
indicated above. Do not apply Gramoxone Extra in suspension­
type liquid fertilizer. Observe all directions for use, precau­
tions and limitations on the respective product labels when 
applying these products in tank mix combination. 
~: When applying Bicep 4.5L and Bladex in tank mix combina­
tion, follow directions under Conventional~illage above to en­
sure compatibility of these products in the tank mixture.

coloration or other form of injury to the desirable perennial 
grasses may occur following application. 
Notes: (1) Keep off desirable flowers, ornamentals and shrubs. 
(2) Do not attempt to reseed treated roadsides with desirable 
perennial grasses for 12 months after application. To avoid 
illegal residues, (3) Do not cut or feed roadside grass, hay and 
(4) Do not allow livestock to graze treated areas. 
Storage and Disposal 
Pesticide Disposal 
Storage 
Ground water contamination may be reduced by diking and flooring 
of permanent liquid bulk storage sites with an impermeable mate­
rial. 
Do not contaminate water, food or feed by storage or disposal, 
or cleaning of equipment. Open dumping is prohibited. Improper 
disposal of unused pesticide, spray mixture, or rinsate is a 
violation of federal law. Pesticide, spray mixture, or rinsate 
that cannot be used according to label instructions must be dis­
posed of according to federal, state or local procedures. For 
guidance in proper disposal methods, contact your State 
Pesticide or Environmental Control Agency, or the Hazardous 
Waste Representative at the nearest EPA Regional Office. 
Container Disposal 
Do not reuse empty container. Triple rinse (or equivalent), 
puncture and dispose of in a sanitary landfill, or by incinera­
tion, or by open burning, if allowed by state and local authori­
ties. If burned, keep out of smoke. 
For minor spills, leaks, etc., follow all precautions indicated 
on this label and clean up immediately. Take special care to 
avoid contamination of equipment and facilities during cleanup 
procedures and disposal of wastes. In the event of a major 
spill, fire or other emergency, call 1-800-888-8372 day or 
night.

-27-
Follow manufacturer's instructions for cleaning/maintaining 
PPE. If no such instructions for washables, use detergent and 
hot water. Keep and wash PPE separately from other laundry. 
Engineering controls statement: 
When handlers use closed systems, enclosed cabs, or aircraft in 
a manner that meets the requirements listed in the Worker Pro­
tection Standard (WPS) for agricultural pesticides [40 CFR 
170.240 (d) (4-6»), the handler PPE requirements may be reduced 
or modified as specified in the WPS. 
Jser Safety Recommendations: 
Users should: 
• Wash hands before eating, drinking, chewing gum, using 
tobacco or using the toilet. 
• Remove clothing immediately if pesticide gets inside. Then 
wash thoroughly and put on clean clothing. 
Environmental Hazards 
For terrestrial uses, do not apply directly to water, or to 
areas where surface water is present, or to intertidal areas 
below the mean high water mark. Do not contaminate water when 
disposing of equipment wash waters. ~his pesticide contains 
atrazine, which has been shown to be tcxic to aquatic inverte­
brates. Runoff and drift from treated areas may be hazardous 
to aquatic organisms in neighboring areas. 
Ground Water and Surface Water Advisory 
Bicep 4.5L contains both the active Llgredients atrazine and 
metolachlor. 
Atrazine can travel (seep or lea~h) through soil and can enter 
ground water 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 agricul­
tural agencies can provide further information on the type of 
soil in your area and the location of ground water . 
...

-28-
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 near the surface. Following application and 
during rainfall events that cause runoff, metolachlor may reach 
surface water bodies including streams, rivers, and reservoirs. 
Care must be taken when using this product to prevent back 
siphoning into wells, spills, or improper disposal of excess 
pesticide, spray mixtures, or rinsates. 
Chec~ valves or antisiphoning devices must be used on all mix­
ing equipment. 
This product may not be mixed/loaded or used within 50 feet of 
all wells, including abandoned wells, drainage wells and sink 
holes. Operations that involve mixing, loading, rinsing, or 
washing of this product into or from pesticide handling or 
application equipment or containers within 50 feet of any well 
are prohibited unless conducted on an impervious pad con­
structed to withstand the weight of the heaviest load that may 
be positioned on or moved across the pad. Such a pad shall be 
designed and maintained to contain any product spills or equip­
ment leaks, container or equipment rinse or wash-water, and 
rain-warp.r that may fallon the pad. Surface water shall not 
be allowed to either flow over or from the pad, which means the 
pad must be self-contained. The pad shall be sloped to facili­
tate material removal. An unroofed pad shall be of sufficient 
capacity to contain at a minimum 110% of the capacity of the 
largest pesticide container or application equipment on the 
pad. A pad that is covered by a roof of sufficient size to 
completely exclude precipitation from contact with the pad 
shall have a minimum containment capacity of 100% of the 
capacity of the largest pesticide container or application 
equipment on the pad. Containment capacities as described 
above shall be maintained at all times. The above-specified 
minimum containment capacities do not apply to vehicles when 
delivering pesticide shipments to the mixing/loading site. 
States may have in effect additional requirements regarding 
well-head setbacks and operational area containment. 
This product may not be mixed or loaded within 50 feet of 
intermittent streams and rivers, natural or impounded lakes and 
reservoirs. This product may not be applied aerially or by 
ground within 66 feet of the points where field surface water 
runoff enters perennial or intermittent streams and rivers or 
within 200 feet around natural or impounded lakes and reser­
voirs. If this product is applied to highly e~odible land, the 
66-foot buffer or setback from runoff entry points must be 
planted to crop or seeded with grass or other suitable crop .

Environmental Hazards 
For terrestrial uses, do not apply directly to water, or to 
areas where surface water is present, or to intertidal areas 
below the mean high water mark. Do not contaminate water when 
disposing of equipment wash waters. This pesticide contains 
atrazine, which has been shown to be toxic to aquatic inverte­
brates. Runoff and drift from treated areas may be hazardous to 
aquatic organisms in neighboring areas. 
~round Water and Surface Water Advisory 
Bicep 4.SL contains both the active ingredients atrazine and 
metolachlor. 
Atrazine can travel (seep or leach) through soil and can enter 
ground water 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 agricultural 
agencies can provide further information on the type of soil in 
your area 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
