GENERAL INFO"MATION 
Cheyenne Herbicide is a broad-spectrum postemergence herbicide for the control of 
both grass and broad leaf weeds in winter wheat, hard red spring wheat and some soft 
white spring wheat varieties (Wakanz, Waverly, Sprite, Owens, Twin and Centennial). 
Grass weeds controlled include wild oats, green foxtail (pigeongrass), volunteer and 
wild millet species. In addition, several broadleaf weeds are controlled including 
kochia, red root pigweed, wild mustard, and common lambsquarters. 
This twin pack of Cheyenne Herbicide contains 3.5 gallons of Cheyenne FM Herbicide 
(marked container number 2) and 0.375 pound of X-TRA Herbicide (marked container 
,~number 1). All of the components in the Cheyenne Herbicide package MUST be 
tank mixed according to the mixing instructions in this label and applied 
according to the recommendatio,)s given in the following Application Directions 
section, or a reduction in weed control and/or a potential for crop injury will 
occur. 
DO NOT apply to barley or durum wheat. 
INFORMATION ON HERBICIDE TOLERANT WEEDS 
Repeated use of the same herbicide, or herbicide with the same mode of action, may result 
in tolerant weeds that will multiply to economic infestations if such herbicides are used year 
after year on the same fields. If such weed infestations appear, herbicides of a different 
mode of action should be considered or the field should be planted to a different crop that 
involves the use of a herbicide with a different mode of action. For further information, 
contact an AgrEvo USA Company representative or your State Weed Science Specialist.

~~/'l 
APPLICATION DIRECTIONS 
Cheyenne Herbicide controls annual grassy and broadleaf weeds with one rate of 
application. One box of Cheyenne Herbicide will treat 40 acres of wheat. One box of 
Cheyenne Herbicide contains two 20-acre units. Each unit consists of one container of 
Cheyenne FM and one container of X-TRA Herbicide. The Cheyenne FM Herbicide 
must always be tank mixed with the X-TRA Herbicide prior to use to insure crop 
safety and adequate weed control. 
Ground Application: DO NOT apply when winds are gusty, or when conditions will 
favor movement of spray particles off the desired spray target. To avoid drift and 
insure consistent weed control, apply Cheyenne FM Herbicide with the spray boom as 
low as possible while maintaining a uniform spray pattern. Apply a minimum of 10 
gallons of spray solution per acre, using a spray pressure of 30-40 psi with flat-fan 
nozzle tips spaced 10 to 20 inches apart across the boom. Ground speed for application 
should not exceed 10 mph. DO NOT apply with hollow cone type insecticide nozzles or 
other nozzles that produce a fine droplet spray. Under dense weed populations, 
high spray volume (15-20 gpa) is required for obtaining thorough coverage. 
Aerial Application: Calibrate the spray equipment prior to use. Cheyenne Herbicide 
should be applied in a minimum of 5 gallons of water per broadcast acre. To get 
uniform spray coverage, use nozzles to provide 200-350 micron size droplets. DO 
NOT use raindrop 'nozzles. Aerial applications with this product should be made at a 
maximum height of 10 feet above the crop with low drift nozzles at a maximum pressure 
of 40 psi. Avoid application under conditions where uniform coverage cannot be 
obtained or where excessive spray drift may occur. Flagmen and loaders should avoid 
inhalation of spray mist and prolonged contact with skin. 
PRECAUTIONS TO BE TAKEN TO AVOID SPRAY DRIFT 
Do not allow spray from aerial equipment to drift onto adjacent land or crops. When 
drift may be a problem, do everything possible to reduce spray drift, including the 
)'following: 
- Do not spray if wind speeds are or become excessive. If sensitive crops or plants 
are downwind, extreme caution must be used under all conditions. Do not spray if 
winds are gusty. 
Use extreme caution when conditions are favorable for drift (high temperatures, 
drought, low relative humidity), especially when sensitive crops are located nearby. 
Drift from aerial applications of the herbicide is likely to result in damage to sensitive 
plants adjacent to the treatment site. This damage can occur at levels below the 
concentrations which can be detected with chemical analysis 
Do not apply when a temperature inversion exists. If inversion conditions are 
suspected, consult with local weather services before making an application. 
Use the lowest number of nozzles practical with the largest possible orifice size 
within the specified range to obtain the minimum 5 gallon per acre spray volume. 
Application height and boom length should be set according to manufacturer's 
instructions to minimize drift.

Page7of14 f fr; 17 
- Reduce the volume of spray mixture by using higher flow rate nozzles. Using lower 
pressure with the appropriate nozzle to obtain higher volumes will also reduce spray 
drift. 
- Apply as close to target plants as practical while maintaining a good spray pattern for 
adequate coverage.

Equipment used in applying MCPA phenoxy herbicide requires special cleaning if it is I I of ('7 
used for applying nonphenoxy herbicides. Failure to properly clean your equipment 
could result in undesirable growth effects or injury to sequentially sprayed plants. See 
Sprayer Cleanup section of this labeling for further information. 
TIMING OF APPLICATION 
Crops: The time of application is determined by the growth stage of the wheat and the 
grassy weed species. Apply Cheyenne Herbicide to spring wheat from the 3-leaf stage 
to the end of tillering (6-leaf) stage of growth. Winter wheat should have a minimum of 
3 tillers before application. 
Do Not Spray Spring or Winter Wheat after Jointing Begins. 
Weeds: Cheyenne Herbicide will control wild oats in the 1-to 4-leaf stage of growth and 
green foxtail in the 2-leaf to 2-tiller stage of growth. Annual broadleaf weeds should 
have grown beyond the cotyledon stage but less than 4 inches tall or in diameter. 
Applications should be made to young, actively growing weeds. 
Cheyenne Herbicide will only control emerged grassy and broadleaf weeds. 
OPTIMUM CONDITIONS FOR WILD OAT CONTROL 
Low soil moisture levels, low humidity, and high temperatures will interact to reduce the 
wild oat control by Cheyenne Herbicide. 
The following conditions will result in optimum wild oat control: 
a. adequate soil moisture which occurs under normal rainfall or in soil following 
a fallow year 
b. temperatures generally lower than 85°F for several days prior to application 
Green foxtail (pigeongrass) is controlled over a wide range of soil moisture conditions. 
However, foxtail showing drought stress and exhibiting rolled leaves ("onion leaf') 
should not be sprayed as poor control may result. 
TANK MIX COMBINATIONS 
When tank-mixing, read and follow the label for each tank-mix product used for 
precautionary statements, directions for use, weeds controlled, geographic and other 
restrictions. Use in accordance with the most restrictive of label limitations and 
precautions. No label dosage should be exceeded. This product cannot be mixed with 
any product containing a label prohibition against such mixing.

Page 10 of 14 
Starane can be tank mixed with Cheyenne to offer control of resistant biotypes of 
kochia. Buctril, Stinger or Tordon 22K can be tank mixed with Cheyenne to improve 
wild buckwheat control. These tank mixes should be used when wild buckwheat 
infestations are heavy and the wild oats are in the 2-10 3-leaf stage of growth. 
Broadleaf Herbicide Rate 
Starane 1/3 ptiA 
Stinger 20zlA 
Buctril 2EC • 0.37 - 0.5 ptiA 
Tordon 22K 0.5 - 0.75 ozJA 
• Equivalent generic bromoxynil products may be substituted in a tank mix for these 
products 
NOTE: When tank-mixing Cheyenne Herbicide with the recommended herbicides 
above, do not exceed the rate shown for each tank mix partner, as reduced wild oat 
control may occur. 
MIXING INSTRUCTIONS 
1. Assure the spray tank is thoroughly clean. 
2. Fill the spray tank with one-half of the total amount of clean water required for the 
application and start the agitation or by pass system. 
3. ALWA YS first add the recommended amount of X-TRA Herbicide (container #1), 
,- into 3 to 4 gallons of clean water in a separate container and mix until the X-TRA 
Herbicide is fully suspended. ALWAYS use a clean container to mix the preslurry of 
X-TRA Herbicide with water to ensure complete suspension. 
4. Add the suspension of X-TRA Herbicide to the partially filled spray tank. Agitate 
thoroughly until all of the suspension is completely mixed. 
5. Add the recommended amount of Cheyenne FM Herbicide (container #2) and 
continue agitation.

Notes 
1. Where routine spraying practices include shared equipment frequently being 
switched between applications of X-TRA and applications to sensitive crops during 
the same spray season, it is recommended a sprayer be dedicated to X-TRA to 
further reduce the chance for injury to sensitive crops. 
2. DO NOT use chlorine bleach with ammonia. Mixing of these materials will release a 
gas with a musty chlorine odor which can cause eye, throat and lung irritation. DO 
NOT clean equipment in an enclosed area. 
USE PRECAUTIONS FOR CHEYENNE HERBICIDE 
1. DO NOT apply to the following crops: barley, corn rye or oats. 
2. DO NOT spray spring or winter wheat after jointing begins. 
3. Rainfall within 4 hours after an application may cause a reduction in weed control. 
4. DO NOT apply more than 1 application in a growing season. 
5. DO NOT app-fy Cheyenne Herbicide within 60 days of harvesting wheat in the 
states of Minnesota, Montana, North Dakota and South Dakota. DO NOT apply 
Cheyenne Herbicide with 70 days of harvest in all other states. 
6. DO NOT apply this product through any type of irrigation system. 
7 DO NOT apply any pesticides other than those listed on this label within 5 days of a 
Cheyenne Herbicide application as reduced grassy weed control may occur. 
8. DO NOT tank mix Cheyenne Herbicide with other herbicides, surfactants or liquid 
fertilizers unless specifically recommended on the Cheyenne Herbicide label.
