Personal Protective Egu~nt: 
Applicators and other handlers must wear: 
• Long-sleeved shirt and long pants 
• Chemical-resistant gloves 
• Chemical-resistant footwear plus socks 
• Protective eyewear 
Discard clothing and other absorbent materials that have been 
drenched or heavily contaminated with this product's concen­
trate. Do not reuse them. Follow manufacturer's instruc­
tions 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 Statements: When handlers use closed 
systems or enclosed cabs in a manner that meets the require­
ments listed in the Worker Protection Standard (WPS) for ag­
ricyltural pesticides [40 CFR 170.240(d) (4-6)], the handler 
PPE requirements may be reduced or modified as specified in 
the WPS. 
Usar Safety Recommendations: 
Users should: 
• Wash hands before eating, drinking, chewing gum, using 
tobacco or using the toilet. 
• Re~ove 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. 00 not contaminate water 
when disposing of equipme~t wash waters. This pesticide con­
tains atrazine, which hdS been shown to be toxic to aquatic 
invertebrates. Runoff and drift from treated areas may be 
hazardous to aquatic organisms in neighboring are~~. 
Ground Water and Surface Water Advisory 
Bicep OF contains both the active ingredients atrazine and 
metolachlor. 
BeST AVAILABLE CO ...

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 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 rin~ates. 
Check valves or antisiphoning devices must be used on all 
mixing equipment. 
This product may not be mixed/loaded or used within 50 feet 
of all wells, includi~g abandoned wells, drainage wells, and 
sink holes. 
Operations that ipvolve mixing, loading, rinsing, or washing 
of this product into or from pesticide handling or applica­
tion equipment or containers within 50 feet of any well are 
prohibited unless conducted on an impervious pad constructed 
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 
equipment leaks, container or equipment rinse or wash-water, 
and rain-water 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 facilitate 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 precipit.ation 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.

General Information 
Bicep OF is a selective herbicide recommended as an early pre­
plant, preplant surface-applied, preplant incorporated, preemer­
gence, postemergence broadcast or pos~emergence-directed treat­
ment for control of most annual grasses and broadleaf weeds in 
corn and as an early preplant, preplant surface-applied, pre­
plant incorporated, or preemergence treatment for control of 
most annual grasses and broadleaf weeds in grain or forage sor­
ghum provided the sorghum seed has been properly treated by the 
seed company with Concep®. This product may be tank mixed with 
Banvel®, Bladex® (4L, BOW, 900F), Oual® formulations, AAtrex® 4L 
(BOW, Nine-O®), Lorox® or eqaivalent, or Princep® 4L (BOW or 
Caliber 90®) for weed control in conventional tillage corn. 
This product may also be tank mixed with either Gramoxone® Extra 
or Roundup® alone or in combination with AAtrex, Bladex, Oual 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 OF), 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 OF in combina­
tion or ~n ~~quence with registered herbicides which do not con­
tain triazines. Consult with your State Agricultural Extension 
Service for specific recommendations. 
Precautions: 1) If sorghum seed is not properly pretreated with 
Concep. Bicep OF will severely injure the crop. 2) Injury may 
occur to corn or sorghum follow'_ng the use of Bicep OF under 
abnormally high soil moisture conditions during early develop­
ment of the crop. 
Bicep OF alone or in tank mixture with AAtrex, Bladex, Dual, or 
Princep may be applied early preplant, preplant-surface, pre­
plant incorporated, or preemergence on corn in water or fluid 
fertilizer. Bicep OF may be applied in tank mix combination 
with Gramoxone Extra or Roundup with or without the above herbi­
cides preplant surface or preemergence to corn. Apply the early 
postemergence treatment on corn in water only. Bicep OF alone 
may also be applied on sorghum early preplant, preplant incorpo­
rated, preplant-surface or preemergence in water or in flqid 
fertilizer. 
To avoid spray drift, do not apply under windy conditions. 
Avoid spray overlap, as crop injury may result. 
00 not apply this product through any type of irrigation system.

Dry weather following preemergence application of Bicep DF or 
a tank mixture may reduce eff~ctiveness. Cultivate if weeds 
develop in conventi0nal tillage corn or sorghum. 
Observe all precautions and limitations on the label of each 
product used in tank mixtures. 
Thoroughly clean sprayer or other application device before 
using. Dispose of cleaning solution in a responsible manner. 
Do not use a sprayer or applicator contamjnated with other mate­
rials, or crop damage or sprayer clogging of the application 
device may occur. 
Mixing Instructions 
Thoroughly recirculate larger containers and bulk tanks before 
using. Bicep OF is a dry flowable that may be mixed with water 
or fluid fertilizer and applied as a spray. 
hpplication in Water or Fluid Fertilizers 
Bicep OF Alone: Fill the spray tank one-half to three-fourths 
full with water or fluid fertilizer, add the proper amount of 
Bicep OF, then add the rest of the water or fluid fertilizer. 
Provide vigorous agitation during mixing and application to 
maintain a uniform suspension. 
Tank Mixtures: Fill the spray tank one-half to three-fourths 
full with water or fluid fertilizer, add the proper amount of 
Bicep DF, then add AAtrex, Banvel®, linuron, or Princep; next 
add Dual; then add Gramoxone Extra or Roundup, depending on the 
tank mix cOinbination desired; and finally add the rest of the 
water or fluid fertilizer. When Bladex is used in the tank 
mixture, add it before Bicep DF unless otherwise specified. 
(See Bladex section under Bicep DF Combinations - Corn for fur­
ther mixing instructions.) Provide vigorous agitation during 
mixing and application to maintain a uniform suspension. 
Compatibility Test: Check the compatibility of Bicep DF 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 ~heck compatibility each time before reuse. Be espe­
cially careful when using complete suspension or fluid fertiliz­
ers as serious compatibility problems are more apt to occur. 
Commercial application equipment may improve compatibility in 
some ins~ances. The follow~ng test assumes a spray volume of 25 
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 one-quart jars with 
tight lids. 
9EST AVAILABLE CO"

) 0 
-7-
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 Unite® (1/4 tsp. is equi~alent 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 emulsifi­
able concentrates last. After each addition, shake or 
stir gently to thoroughly mix. The appropriate amount of 
herbicides for this test follows: 
Dry herbicides: For each pound to be applied per acre, 
add 1.4 teaspoons to each jar. 
Liquid herbicides: 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, 
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 agita­
tion is used. If the mixtures are incompatible, test the 
following methods of improving compatibility: (A) slurry 
the dry herbicides(s) in water before addition, or (B) add 
1/2 of the compatibil~ty agent to the fer.tilizer and the 
other 1/2 to the emulsifiable concentrate or flowable her­
bicide before addition to the mixture. If still incom­
patible, do ~ot ~se the mixture. 
5) After compatibility testing is complete, dispose of any 
pesticide wastes in accordance with the dir€ctions in the 
Storage and Disp05al section at the end of this label. 
Application Procedures 
Ground Application: Use sprayers that provide accurate and uni­
form application. Screens in nozzles should be no finer than 
50-mesh. Suction and in-line screens should be no finer than 
16-mesh. Use a pump with capacity to (1) maintain 35-40 psi at 
the nozzles, and (2) provide 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 ~pplied per acre 
as follows: 
band width in inches 
width in inches

3) If available, sprinkler irrigate within 2 days after 
application. Apply 1/2-1 inch of water. Use lower water 
volume (1/2 inch) on coarse-textured soils and higher vol­
ume (1 inch) on finer textured soils. 
4) If irrigation is not possible and rain does not occur 
within 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.

with minimum-tillage or no-tillage systems in CO, lA, IL, IN, 
KS, KY, MN, MO, MT, NO, NE, SO, TN, WI, and WY. Apply 2/3 the 
recommended rate of Bicep OF as a split treatment 30-45 days 
before planting and the remainder at planting using the rates in 
Table 1. 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 coarse-textured soils, 
apply 6.6 Ibs./A not more th?n 2 weeks prior to planting. The 
above procedure may be followed if A~trex or Dual or Princep is 
used in tank mixtures with Bicep DF. 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 
syster.1s in DE, MO, MI, NY, OH, PA, VA, AND WV, early preplant 
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 trectment, a post­
emergence application of an appropriately labeled broadleaf 
and/or grass weed herbicide may be used, i.e., AAtrex,

Basagran®, 2,4-D, Banvel, bromoxynil (Brominal® or Buctril®). 
If the postemergence treatment includes the herbicide used early 
preplant, do not exceed the labeled rate for corn on a given 
soil texture. Observe all direction~ for use, precautions, and 
limitations on the label of the postemergent herbicide. 
Bicep DF may be used according to the above directions to con­
trol winter wheat planted as a cover crop in IN, KY, and OH, in 
addition to providing residual weed control. The wheat must be 
less than 6 inches tall (preferably still in a dormant or semi­
dormant state coming out of winter) at the time of application. 
Depending on rainfall, 10-20 days may be required to completely 
kill the wheat. In the event that adequate rainfall does not 
occur, control of the winter wheat may be unsatisfactory and the 
application of a contact herbicide (i.e., Gramoxone Extra or 
Roundup) may be required before planting the crop. 
On medium- and fine-textured soils following final seed bed 
preparation in the Blackland and Gulf Coast areas of TX, an 
early preplant application of Bicep DF at 4.9 to 5.9 lbs./A may 
be made 30-45 days before planting. Grass suppression of 
2-3 weeks after planting can be expected as a result of this 
application. Do not incorporate or disturb the soil before 
planting and avoid moving the soil during the planting op~ra­
tion. A follow-up application of Dual may be needed in fields 
with a history of heavy grass pressure. Apply after planting, 
but before corn and grass weeds emerge. 
Notes: (1) If a follow-up application of Dual is needed, do not 
exceed a total of 2.5 lbs. ai of meto1achlor/A including the 
preplant Bicep DF application on medium or fine-textured soils. 
On fine-textured soils wit .. more than 3% organic matter, do not 
exceed 3 Ibs. ai of metolachlor. (2) 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.

Rotational Crops: (1) If treated crop is lost due to poor 
germination, hail, flood, insects, etc., corn may be replanted 
immediately or sorghum may be replanted immediately provided the 
seed has been properly treated with Concep. Do not make a 
second 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 planted the spring 
following treatment. Do not graze or feed forage or fodder from 
cotton to livestock or illegal residues may result. (3) Injury 
may occur to soybeans planted the year following application on 
soils having a calcareous surface layer. (4) In eastern parts 
of the Dakotas, KS, I estern MN and NE, do not rotate to soybeans 
sooner than 18 months after application if the rate applied to 
corn or sorghum was more than 2.0 lbs. ai of atrazine or equiva­
lent band application rate, or soybean injury may occur. (5) If 
applied after June 10, do not rotate with crops other than corn 
or sorghum the next year, or crop injury may occur. (6) In the 
High Plains and Intermountain areas of the West where rainfall 
is sryarse and erratic or where irrigation is required, use only 
when corn or sorghum is to follow corn or sorghum, or a crop of 
untreated corn or sorghum is to precede other rot~tional ~rops. 
(7) Do not plant sugar beets, tobacco, vegetables (including dry 
beans), spring-seed:; small grains, or small seeded legumes the 
year following application, or injury may occur. (8) All other 
crops may be planted 12 months after application.

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 herbicides Gramoxone Extra 
or Roundup should be tank mixed with Bicep OF alone or with 
Bicep OF plus AAtrex, Bladex, Dual, or Princep. When used as 
directed, the Gramoxone Extra portion of the tank mixture con­
trols 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 OF portion of the tank mixture provides preemergence 
control of the weeds listed on this label in the Bicep OF Alone 
section for corn. The addition of AAtrex, Bladex, Dual, or 
Princep offers the advantage indicated for each under "Conven­

with AAtrex or Bladex. When used as directed, t.he Bicep OF 
portion of the t~nk mixture provides preemergence control of the 
weeds listed on this label in the Bicep OF Alone section for 
corn. The addition of AAtrex or Bladex offers the advantage 
indicated for each under "Conventional Tillage" above. 
Application: Apply Bicep OF before, during, or after planting 
but before corn emerges, at the appropriate rate in Table 7. Up 
to 1 qt. of AAtrex 4L (1.25 lbs. SOW or 1.1 Ibs. Nine-O) or 2 
qts. of Bladex 4L (2.5 Ius. SOW or 2.2 lbs. gOOF) per acre may 
be added to the rate of Bicep OF recommended in Table 7. 
Where heavy crop residues exist, add an appropriately labeled 
2,4-D amine or low volatile ester to the spray tank last and 
apply in a minimum ef 25 gals. of carrier/A. 
As carriers, nitrogen solutions and complete liquid fertilizers, 
applied before cern emergence, ~nhance burndown of existing 
weeds, and therefore are recommended instead of water. Add 
X-77® surfactant at 1.0-2.0 qts./100 gals. of diluted spray, or 
another surfactant cleared for use on growing crops at its 
recommended rate. Apply before weeds exceed 3 inches in height. 
If alfalfa is present, add Banvel to the spray mixture at

heiyht. 
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

Tank Mixtures of Bicev OF with Gramoxone Extra or Roundup for 
Minimum-Tillage or No-Tillage Systems 
In minimum-tillage or no-tillage systems where grain sorghum is 
planted directly into a cover crop, stale seedbed, established 
sod, or previous crop residues, the contact herbicides Gramoxone 
Extra or Roundup may be tank mixed with Bicep OF. When used as 
directed, the Gramoxone Extra portion of the tank mixture con­
trols 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 OF portion of the tank mixture provides preemergence 
control of the weeds listed on this label in the Bicep OF 
A~plied Alone section. 
Refer to the label of each product used in combination and 
observe the planting details, restrictions, and all other pre­
cautions and limit~tions.

Gramoxone Extra or Roundup at the following broadcast rates: 
Gramoxone Extra: 1.5-2.0, 2.0-2.5 or 2.5-3.0 pts. per 
acre to 1-3 inches, 3-6 inches, or 6 inch tall weeds, 
respectively. Apply surfactant at 1 or 2 pts. per 
100 gals. of spray mixture with 75% or greater or 50-74% 
nonionic active ingredient, 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. 
Apply in a minimum of 20 gals. of water per acre with conven­
tional spray equipment.

Roadsides 
To control certain annual weeds in established perennial grasses 
along roadsides in CO, KS, MT, ND, NE, SD, and WY, including 
barnyardgrass, cheatgrass (downy brome, chess:, common (annual) 
broomweed, crabgrass, fall panicum, giant foxtail, goosegrass, 
green foxtail, little barley, medusahead, sagewort, tumble 
mustard, witchgrass, and yellow foxtail, broadcast 1.5 qts./A in 
a minimum of 10 gallons of water by ground equipment in the fall 
before ground freezes, or after thawing in the spring, but 
before the established grasses green-up and before weeds emerge. 
Examples of desirable established grasses include big bluestem, 
bluegrama, bromegrass, buffalograss, crested wheatgrass, Indian­
grass, little bluestem, side-oats grama, switchgrass, and west­
ern wheatgrass. Apply only once a year. Temporary discolora­
tion or oth~r form of injury to the desirable perennial grasses 
may occur fo:lowing 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 Dispos~ 
Storage 
Ground water contamination may be reduced by diking and flooring 
of permanent liquid bulk storage sites with an impermeable 
material. 
Pesticide Disposal 
Do not contaminate water, food, or feed by storage, 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
