FAILURETO FOLLOW THE DIRECTIONS FOR USE AND PRECAU­
TIONS ON THIS LABEL MAY RESULT IN POOR WEED CONTROl, 
CROP' INJURY, OR ILLEGAL RESIDUES. 
GENERAL INFORMATION 
Bicep II is a selective herbicide recommended before planting, before or 
after emergence (see directions) for control of most annual grasses and 
broadleaf weeds in com. Bicep II can also be used before crop emer­
gence for control of most annual grasses and broadleaf weeds in grain or 
forage sorghum provided the sorghum seed has been properly treated by 
the seed company with Concep® or Screen®. This product may be tank 
mixed with AAtreX® 4L (Nine-O®), Dual® formulations, Princep® 4L 
(Caliber 90®), Banvel®, BladeX® (4L, 90DF) formulations, Extrazine® II, 
LoroX® or equivalent for weed control in conventional tillage com. This 
product may also be tank-mixed with other herbicides specified on this 
label for weed control in conventional, minimum till, and no-till com, grain 
sorghum, or forage sorghum. 
Note: Tank mixtures are permitted only in those states where the tank­
mix partner is registered. 
Following many years of continuous use of atrazine (one of the ingredi­
ents in Bicep II), 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 controlled by this product are expected to be present along with 
resistant biotypes, we recommend the use of Bicep II in combination or in 
sequence with registered herbicides which do not contain triazines. 
Consult with your State Agricultural Extension Service for specific 
recommendations. 
Precautions: (1) If sorghum seed is not properly pretreated with Concep 
or Screen, Bicep /I will severely injure the crop. (2) Injury may occur to 
sorghum following the use of Bicep /I under abnormally high soil moisture 
conditions during early development of the crop. 
Bicep II alone or in tank mixture with AAtrex, Cycle, Dual, Princep, or 
Bladex may be applied early preplant, preplant surface, preplant < < •• 
incorporated, or preemergence on com in water or fluid fertilizer. Apply < < < • 
postemergence treatments of Bicep II to com using water only as the :', < 
carrier. Bicep II may be applied in tank-mix combination with Grf.llJ1Qxone 
Extra, Landmaster BW, or Roundup with or without the above hsrbid:des

Bicep II 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. 
Do not apply under conditions which favor runoff or wind erosion of soil 
containing this product to non-target areas. 
To prevent off-site movement due to runoff or wind erosion, 
(1) Avoid treating powdery dry or light sand soils when conditions are 
favorable for wind erosion. Under these conditions, the soil surface 
should first be settled by rainfall or irrigation. 
(2) Do nbt apply to impervious substrates such as paved or highly com­
pacted surfaces. 
(3) Do not use tailwater from the first flood or furrow irrigation of treated 
fields to treat non-target crops unless at least liz inch of rainfall has 
occurred between application and the first irrigation. 
Where reference is made to weeds partially controlled, partial control can 
either mean erratic control from good to poor or consistent control at a 
level below that generally considered acceptable for commercial weed 
control. 
Dry weather following preemergence application of Bicep /I or a tank mix­
ture may reduce effectiveness. Cultivate if weeds develop in conventional 
tillage com 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 contaminated with other materials, or crop damage 
or sprayer clogging of the application device may occur.

Dry Bulk Granular Fertilizers 
Many dry bulk granular fertilizers may be impregnated or coated with 
Bicep II and used to control weeds in com or Concep-treated sorghum. 
When applying Bicep II with dry bulk granular fs:iilizers, follow all direc­
tions for use and precautions on the Bicep II label regarding target crops, 
rates per acre, soil texture, application methods, and rotational crops. 
All individual state regulations relating to dry bulk granular fertilizer blend­
ing, registration, labeling, and application are the responsibility of the indi­
vidual 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 II onto the fertilizer must be placed to provide uniform 
spray coverage. Care should be taken to aim the spray onto the fertilizer 
only, avoiding the walls of the blender. 
If the herbicide/fertilizer mixture is too wet, add a highly absorptive mater­
ial, such as Agsorb® EG. or Celatom MP-79®, or similar granular clay or 
diatomaceous earth materials, to obtain a dry, free-flowing mixture. 
Absorptive materials should be added only after the herbicide has been 
thoroughly blended into the fertilizer mixture. Best application results will 
be obtained by using a granule of 6/30particle size or of a size similar to 
that of the fertilizer material being used. Generally, less than 2% by 
weight of absorptive material will be needed. Avoid using more than 5% 
absorptive material by weight. 
Calculate the amount of Bicep II to be used by the following: 
2,000 
Ibs. of 
fertilizer 
per acre 
x 
qts. of Bicep II 
per acre = 
Pneumatic (Compressed Air) Application 
qts. of Bicep II 
per ton of 
fertilizer 
High humidity, high urea concentrations, low fertilizer use rates, and 
dusty fertilizer may cause fertilizer mixtures to build up or plug the distrib­
utor head, air tubes, or nozzle deflector plates. To minimize buildup, pre-
• mix Bicep II with Exxon Aromatic 200 at a rate of 2.0-2.5 pts./gal. of 
Bicep II. Aromatic 200 is a noncombustible/nonflammable petroleum 
product. Aromatic 200 may be used in either a fertilizer blender or :' •• : • 
through direct injection systems. Drying agents should not be u~€!r.I When 
using Aromatic 200. ~ ': 
t, l" ( 
, , 
Notes: (1) Mixtures of Bicep II and Aromatic 200 must be used on'c\ry 
fertilizer only. Poor results or crop injury may result if these mixt~r~:S: are

used in water or liquid fertilizer solutions for spraying applications. 
(2) When impregnating Bicep II in a blender before application, a drier 
mixture can be attained by substituting a drying agent forl\.romatic 200. 
The use of Agsorb EG. or another drying agent of 6/30 particle size is 
recommended. (3) Drying agents are not recommended for use with On­
The-Go impregnation equipment. 
Precautions: To avoid potential for explosion, (1) Do not impregnate Bicep 
II on ammonium nitrate, potassium nitrate, or sodium nitrate, either alone 
or in blends with other fertilizers. (2) Do not combine Bicep fI with a sin­
gle superphosphate (0-20-0) or treble superphosphate (0-46-0). (3) Do 
not use Bicep II on straight limestone, since absorption wi// not be 
achieved. Fertilizer blends containing limestone can be impregnated. 
Application 
Apply 200-700 Ibs. 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 herbi­
cide/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 conventional 
tillage is practiced, a shallow incorporation of the mixture 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 /I impregnated onto dry bulk granular fertil­
izers can be expected to last longer in the soil than when Bicep /I is 
applied as a spray in water or fluid fertilizer. (2) To avoid potential crop 
injury, do not use the herbicide/fertilizer mixture on crops where planting 
beds are to be formed. 
Application in Water or Fluid Fertilizers 
Bicep II Alone: Fill the spray tank '12-3/. full with water or fluid fertilizer, 
add the proper amount of Bicep II, 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 '12-3/. full with water or fluid f~rtUi1..er, 
add the proper amount of Bicep II, then add AAtrex, Banvel, Iinilroh,:or 
Princep; next add Dual; then add Gramoxone Extra, LandmastGr :3\,>;, or 
Roundup, depending on the tank-mix combination desired; and finliily, 
add the rest of the water or fluid fertilizer. When Bladex is used:(~ t~G

tank mixture, add it before Bicep II, unless othelWise specified. (See 
Bladex section under Bicep II 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 II and tank mixtures 
in fluid fertilizer by mixing proportionate quantities in a small container, as 
described below, before mixing in the spray tank. Nitrogen solutions or 
complete fluid fertilizers 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 especially careful 
when using complete suspension or fluid fertilizers, as serious compatibil­
ity problems are more apt to occur. Commercial application equipment 
may improve compatibility in some instances. The following test assumes 
a spray volume of 25 gals.lA. For other spray volumes, make appropriate 
changes in the ingredients. Check compatibility using this procedure: 
1. Add 1 pt. of fertilizer to each of 2 one-qt. jars with tight lids. 
2. To one of the jars, add 114 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.l100 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 gently to thoroughly mix. The appropriate 
amount of herbicides for this test follows: 
4. 
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. 
After adding all ingredients, put lids on and tighten, and invert each 
jar 10 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 2 jars. If 
( ( , , either mixture'separates, but can be remixed readily, the mixture 
can be sprayed as long as good agitation is used. If the mixtures 
are incompatible, test the following methods of improving compati- ,:'.: 
bility: (A) slurry the dry herbicide(s) in water before addition, or :' , , • 
(B) add '12 of the compatibility agent to the fertilizer and the other 1;' 
to the emulsifiable concentrate or flowable herbicide beforG addition 
to the mixture. If still incompatible, do not use the mixture.' , : ' , : , ,

Application Procedures 
Ground Application: Use sprayers that provide accurate and uniform 
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 (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 applied per acre as fol­
lows: 
band width in inches broadcast rate 
row width in inches X per acre = 
amount needed 
per acre of field 
Low Carrier Application (Broadcast Ground Application Only): Use 
sprayers, such as Ag-Chem RoGator®, Hagie, John Deere Hi-Cycle™, 
John Deere 4700 Sprayer, Melroe Spra-Coupe, Tyler PatrioFM, or 
Willmar Air Ride®, that provide accurate and uniform application. Only 
water may be used as a carrier. Screens in suction and in-line strainers •• ,' 
should be 50-mesh. Manufacturers may require that tip screens as fine ,: .': 
as 1 ~O-mesh be used with some nozzles. Use a pump with capacity to: : ' •• ' 
(1) maintain up to 35-40 psi at the nozzles, and (2) provide suffidel:'t agi­
tation in tank to keep mixture in suspension. Use a minimum of 5.0 gals. 
of spray mixture per acre. Maximum recommended sprayer spE:eil is 15 
mph. Maintain uniform travel speed while spraying. Rinse spra)[~r:: 
thoroughly with clean water immediately after each use. • <: , ,

Note: Low pressure nozzles are recommended to reduce drift and 
increase application accuracy. Care should be taken when using auto­
matic rate-controlling devices to spray the material within the rated work­
ing pressure and flow ranges of the nozzle selected. Nozzle screens 
should be used when recommended by the manufacturer. All nozzles 
should be placed on 20-inch centers, exceptffcoding types which should 
be placed on 40-inch centers. When Flat Fan-type nozzles are used, 
angles of 80" or 110" are recommended. Always read and follow the man­
ufacturer's directions for optimum setup and performance of their nozzles 
or tips. 
Aerial Application (for Bicep II alone): Use aerial application only 
where broadcast applications are specified. Apply a minimum of 1.0 gal. 
of water for each 1.0 gal. of this product applied per acre, but for rates 
below 1.0 gal./A, use in sufficient water to equal 2.0 gals.!A 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 height of 10ft., 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 II 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 ana prolonged contact with skin. 
Aerial Drift Management 
Avoiding spray drift at the application site is the responsibility of the appli­
cator. The interaction of many equipment- and weather-related factors 
determine the potential for spray drift. The applicator and the grower are 
responsible for considering all these factors when making decisions. 
The following drift management requirements must be followed to avoid 
off-target drift movement from aerial applications to agricultural field 
crops. These requirements do not apply to forestry applications, public 
health uses or to applications using dry formulations. 
1. The distance of, the outer most nozzles on the boom must not 
exceed 3/4 the length of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream 
and never be pointed downwards more than 45 degrees. ."",

information covered in the Aerial Drift Reduction Advisory Information 
section below. 
Aerial Drift Reduction Advisory Information 
Information on Droplet Size 
The most effective way to reduce drift potential is to apply large droplets. 
The best drift management strategy is to apply the largest droplets that 
provide sufficient coverage and control. Applying larger droplets reduces 
drift potential, but will not prevent drift if applications are made improper­
ly, or under unfavorable environmental conditions (see Wind, 
Temperature and Humidity, and Temperature Inversions). 
Controlling Droplet Size 
• Volume - Use high flow rate nozzles to apply the highest practical 
spray volume. Nozzles with higher rated flows produce larger droplets. 
• Pressure - Do not exceed the nozzle manufacrurer's recommended 
pressures. For many nozzle types, lower pressure produces larger 
droplets. When higher flow rates are needed, use higher flow rate 
nozzles instead of increasing pressure. 
• Number of nozzles - Use the minimum number of nozzles that provide 
uniform coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is released 
parallel to the airstream produces larger droplets than other orienta­
tions and is the recommended practice. Significant deflection from 
horizontal will reduce droplet size and increase drift potential. 
• Nozzle Type - Use a nozzle type that is designed for the intended 
application. With most nozzle types, narrower spray angles produce 
larger droplets. Consider using low-drift nozzles. Solid stream nozzles 
oriented straight back produce the largest droplets and the lowest drift. 
Boom Length 
For some use patterns, reducing the effective boom length to less than 3/4 
of the wingspan or rotor length may further reduce drift without reducing 
swath width. • • , , 
Application Height 
Applications should not be made at a height greater than 10 fe€t abcve 
the top of the largest plants unless a greater height is required lvl dilcraft 
safety. Making applications at the lowest height that is safe reduces 
exposure of droplets to evaporation and wind. ; : ~ : : '

Swath Adjustment 
When applications are made with a crosswind, the swath will be dis­
placed downward. Therefore, on the up and downwind edges of the field, 
the applicator must compensate for this displacement by adjusting the 
path of the aircraft upwind. Swath adjustmer~ distance should increase, 
with increasing drift potential (higher wind, smaller drops, etc.). 
Wind 
Drift potential is lowest between wind speeds of 2-10 mph. However, 
many factors, including droplet size and equipment type determine drift 
potential at any given speed. Application should be avoided below 2 mph 
due to variable wind direction and high inversion potential. Note: Local 
terrain can influence wind pattems. Every applicator should be familiar 
with local wind patterns and how they affect spray draft. 
Temperature and Humidity 
When making applications in low relative humidity, set up equipment to 
produce larger droplets to compensate for evaporation. Droplet evapora­
tion is most severe when conditions are both hot and dry. 
Temperature Inversions 
Applications should not occur during a temperature inversion because 
drift potential is high. Temperature inversions restrict vertical air mixing, 
which causes small suspended droplets to remain in a concentrated 
cloud. This cloud can move in unpredictable directions due to the light 
variable winds common during inversions. Temperature inversions are 
characterized by increasing temperatures with altitude and are common 
on nights with limited cloud cover and light to no wind. They begin to 
form as the sun sets and often continue into the moming. Their presence 
can be indicated by ground fog; however, if fog is not present, inversions 
can also be identified by the movement of smoke from a ground source 
or an aircraft smoke generator. Smoke that layers and moves laterally in 
a concentrated cloud (under low wind conditions) indicates an inversion, 
while smoke that moves upward and rapidly dissipates indicates good 
vertical air mixing. 
Sensitive Areas .

5. 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 recom­
mended as soon as weeds emerge. 
Bicep II Rate Limitations - Corn and Sorghum" 
'Where there are state/local requirements regarding atrazine use (includ­
ing lower maximum rates and/or greater setbacks) which are different 
from the label, the more restrictive/protective requirements must be fol­
lowed. Certain states may have established rate limitations within spe­
cific geographical areas. Consult your state lead pesticide control 
agency for additional information. It is a violation of this label to deviate 
from state use regulations. 
Note: For purposes of calculating total atrazine active ingredient applied, 
Bicep II contains 2.67 Ibs. a.1. atrazine + relateds per gal. (0.6675 lb.

FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE 
• On Highly Erodible Land (as defined by SCS) 
If conservatior. ti!lage is practiced, leaving at least 30% of the 
soil covered with plant residues at planting, apply a maximum of 
3.0 qtsJA as a broadcast spray. Refer to "s" in tables following. 
If the soil coverage with plant residue is less than 30% at 
planting, a maximum of 2.4 qts.lA may be applied. Refer to "An 
in tables following. 
• On Land Not Highly Erodible 
Apply a maximum of 3.0 qts.lA as a broadcast spray. Refer to 
"s" in tables following. 
FOR POSTEMERGENCE APPLICATION TO CORN 
If no atrazine was applied prior to com emergence, apply a maxi­
mum of 3.0 qts.lA broadcast. If a postemergence treatment is 
required following an earlier herbicide application, the total 
atrazine applied may not exceed 2.5 Ibs. active ingredient (3.75 
qts. of Bicep II) per acre per calendar year. 
Application Timings 
Early Preplant (Corn): Use on medium- and fine- textured soils 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 
Sicep II as a split treatment 30-45 days before planting and the remain-
der 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 2.4 
qts.lA not more than 2 weeks prior to planting. The above procedure may 
be followed if AAtrex or Dual or Princep is used in tank mixtures with 
Sicep II. Substitute a fluid fertilizer for some or all of the water carrier for 
bumdown of existing annual weeds listed on this label up to the 2-leaf ••••• 
stage of development. The addition of crop oil concentrate to the spray.:' ': 
mixture will enhance the bumdown activity. If larger weeds are present at~ ••••

in DE, MD, 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 treat­
ment, a postemergence application of an appropriately labeled broadleaf 
and/or grass weed herbicide may be used, i.e., AAtrex, Beacon®, Banvel, 
Basagran®, bromoxynil (Brominal® or Buctri\®), Exceed®, Marksman®, 
or 2,4-0. If the postemergence treatment includes the herbicide used 
early preplant, do not exceed the labeled rate for com on a given soil tex­
ture. Observe all directions for use, precautions, and limitations on the 
label of the postemergent herbicide. 
Bicep" may be used according to the above directions to control 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 (prefer­
ably 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 applica­
tion of a contact herbicide (Le., Gramoxone EXtra or Roundup) may be 
required before planting the crop. 
On medium- and fine-textured soils following final seed bed preparation 
in the Blacklands and Gulf Coast areas of TX, an early preplant applica­
tion of Bicep" at 1.8-2.2 qts.lA 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 operation. A 
follow-up application of Dual may be needed in fields with a history of 
heavy grass pressure. Apply after planting, but before com and grass 
weeds emerge. 
Notes: (1) If a follow-up application of Dual is needed, do not exceed a 
total of 2.5 Ibs. a.L of metolachlor per acre, including the preplant Bicep" 
application on medium- or fine-textured soils. On fine-textured soils with 
more than 3% organic matter, do not exceed 3 Ibs. a.i. 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 
Do not rotate to food or feed crops other than those listed below: 
(1) If treated crop is lost due to poor germination, hail, flood, insects, etc., 
com may be replanted immediately or sorghum may be replanted imme­
diately, provided the seed has been properly treated with Concep or 
Screen. Do not make a second broadcast application. If the original appli­
cation 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 treat­
ment. 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, western MN, and NE, do not rotate 
to soybeans for 18 months following application if the rate applied to corn 
or sorghum was more than 2.0 Ibs. a.i. of atrazine or equivalent band 
application rate, or soybean injury may occur. (5) If applied after June 10, 
do not rotate with crops other than com or sorghum the next year, or crop 
injury may occur. (6) In the High Plains and Intermountain areas of the 
West, where rainfall is sparse and erratic or where irrigation is required, 
use only when com or sorghum is to follow corn or sorghum, or a crop of 
untreated com or sorghum is to precede other rotational crops. (7) Do not 
plant sugar beets, tobacco, vegetables (including dry beans), spring­
seeded small grains, or small-seeded legumes the year following applica­
tion, or injury may occur.

amine or low volatile ester to the spray tank last and apply in a minimum 
of 25 gals. of carrier per acre. 
As carriers, nitrogen solutions and complete liquid fertilizers, applied 
before corn emergence, enhance burndown of existing weeds, and there­
fore 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 
0.33-0.5 pt./A and apply before alfalfa exceeds 6 inches in height. 
For fields with existing sod grasses (e.g., bromegrass, orchardgrass, 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 direc­
tions for use, precautions, and limitations on the respective product labels 
when applying these products in tank-mix combination. 
Note: When applying Bicep II and Bladex or Extrazine II in tank-mix com­
bination, follow directions under Conventional Tillage to ensure compati· 
bility of these products in the tank mixture. Do not exceed a total of

Bicep II + Exceed: Apply 1.5 to 2.0 qts.!A of Bicep II + 1.0 oz.!A of 
Exceed to com that is 4 to 12 inches tall. The application may be broad­
cast, semi-directed, or directed. The Bicep II rate is based on soil tex­
ture, with 1.5 qts.lA on coarse, and 2.0 qts.!A on medium and fine soils. 
Add a nonionic surfactant at 0.25% vivo 
This mixture is effective for control of many annual broadleaf weeds and 
some grasses. A few instances of broadleaf weed control antagonism 
have been observed with this combination. Control of certain annual 
grasses can be improved with the addition of Accent. 
Bicep II + Exceed + Accent: Apply the same rates of Bicep II and 
Exceed as mentioned above. Add Accent at 0.33 oz.!A for more effective 
control of certain annual grasses. Apply to field corn between 4 and 12 
inches. Add a non ionic surfactant at 0.25% v/v. 
Bicep II + Spirit: Spirit herbicide at 1.0 oz.! A can be SUbstituted in place 
of Exceed in the above combinations in field corn only. 
Notes: Do not use fertilizer or crop oil concentrate with these mixtures or 
injury to field corn may occur. The combination of Bicep II with other 
products for postemergence weed control in corn is generally not recom­
mended. These combinations may cause injury and/or weed control 
concerns that would not exist when the products are used separate­
ly. A certain inherent risk is involved with the various combinations of 
these products used postemergence in corn. It should be noted that 
early preplant, preplant incorporated, or preemergence control of these 
weeds would usually provide more timely weed control resulting in higher 
yields than postemergence treatments.

BICEP II COMBINATIONS - GRAIN SORGHUM (SEED TREATED WITH 
CONCEP OR SCREEN) 
Tank Mixture of Bicep II with Gramoxone Extra, Landmaster BW, 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 sad, or previous 
crop residues, the contact herbicides Gramoxone Extra, Landmaster BW, 
or Roundup may be tank mixed with Bicep II. When used as directed, the 
Gramoxone Extra portion of the tank mixture controls most emerged 
annual weeds and suppresses many perennial weeds. Landmaster BW 
or Roundup combinations will control emerged annual and perennial 
weeds when applied as directed on its label. The Bicep II portion of the 
tank mixture provides preemergence control of the weeds listed on this 
label in the Bicep II Applied Alone section. 
Refer to the label of each product used in combination and observe the 
planting details, restrictions, and all other precautions and limitations. 
Application: Apply before, during, or after planting, but before grain 
sorghum emerges, at the appropriate rate in Table 9. Add Gramoxone 
Extra, Landmaster BW, or Roundup at labeled rates. 
Apply in a minimum of 20 gals. of water per acre with conventional spray 
equipment.

Environmental Hazards 
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 contami­
nate water when disposing of equipment wash water or rinsate. 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. -
Ground Water Advisory 
Bicep If 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, Le., 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 is known to leach through soil into ground water under cer­
tain conditions as a result of agricultural use. Use of this chemical in 
areas where soils are permeable, particularly where the water table is 
shallow, may result in ground water contamination. 
Surface Water Advisory 
Metolachlor can contaminate surface water through ground spray 'drift. 
Under some conditions, metolachlor may also have a high potential for 
runoff into surface water (primarily via dissolution in runoff water), for sev­
eral months post-application. These include poorly draining or wet soils 
with readily visible slopes toward adjacent surface waters, frequently 
flooded areas, areas over-laying extremely shallow ground water, areas 
with in-field canals or ditches that drain to surface water, areas not sepa­
rated from adjacent surface waters with vegetated filter strips, and areas 
over-laying tile drainage systems that drain to surface water.

that involve mixing, loading, rinsing, or washing of this product into or 
from pesticide handling or application equipment or containers within 50 
ft. 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 cc·ntain any product spills or equipment leaks, 
container or equipment rinse or wash-water, and rain-water that may fall 
on 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 
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 ft. of perennial or 
intermittent streams and rivers, natural or impounded lakes and 
reservoirs. This product may not be applied aerially or by ground within 
66 ft. of the points where field surface water runoff enters perennial or 
intermittent streams and rivers or within 200 ft. around natural or 
impounded lakes and reservoirs. If this product is applied to highly erodi­
ble land, the 66-ft. buffer or setback from runoff entry points must be 
planted to crop, or seeded with grass or other suitable crop. 
Tile-Terraced Fields Containing Standpipes 
To ensure protection of surface water from runoff through standpipes with 
tile-outlets in terraced fields, one of the following options may be used: 
1. Do not apply this product within 66 ft. of standpipes in tile-outietted 
terraced fields.

Apply this product to the entire tile-outletted terraced field U:1::e:r a 
no-till practice only when a high crop residue management practice 
is practiced. High crop residue management practice is descric9d 
as a crop management practice where little or no crop resfdue'is 
removed from the field during and after crop harvest.
