ENVIRONMENTAL HAZARDS 
This pesticide is toxic to fish and aquatic invertebrates. Do not apply directly to water, or to ar eas where surface water is present or to 
intertidal areas below the mean high water mark. Do not contam inate any body of water and do not apply when/where conditions co uld 
favor runoff. Do not contaminate water by cleaning of equipment or disposal of equipment washwaters or rinsate. Do not allow sprays to 
drift onto desirable plants. Drift or runoff may adversely affect non-target plants. 
Ground Water Advisory 
Pyrasulfotole is known to leach through soil into ground water under certain conditions as a result of label use. Use of this c hemical in 
areas where soils are permeable, particularly where the water table is shallow, may result in ground-water contamination. 
This chemical has properties and characteristics associated with chemicals detected in groundwater. This chemical may leach int o 
groundwater if used in areas where soils are permeable, particularly where the water table is shallow. 
Users are advised not to apply pyrasulfotole where soils have a rapid to very rapid permeability (such as loamy sand to sand) and the 
water table of an underlying aquifer is shallow or to soils containing sinkholes over limestone bedrock, severely fractured sur faces, and 
substrates which would allow direct introduction into an aquife r. Your local agricultural agencies can provide further informat ion on the 
type of soil in your area and the location of groundwater. 
Surface Water Advisories 
This product may contaminate water through drift of spray in win d. This product has a high potential for runoff for several mon ths or 
more after application. Poorly draining soils and soils with shal low water tables are more prone to produce runoff that contain s this 
product. A level, well maintained vegetative buffer strip betwe en areas to which this product is applied and surface water feat ures such 
as ponds, streams, and springs will reduce the potential for co ntamination of water from rainfall-runoff. Runoff of this produc t will be 
reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. 
This product may impact surface water quality due to runoff of ra in water. This is especially true for poorly draining soils an d soils with 
shallow ground water. This product is classified as having a m edium potential for reaching both surface water and aquatic sedim ent via 
runoff for several months or more after application. A level, we ll-maintained vegetative buffer strip between areas to which th is product 
is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of pyrasulfotole fr om runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is expected to occur 
within 48 hours. 
 
Reporting Ecological Incidents 
To report ecological incidents, including mortality, injury, or harm to plants and animals, call [1-866-99BAYER (1-866-992-2937)]. 
 
Non-Target Organism Advisory 
This product is toxic to plants and may adversely impact the for age and habitat of non-target organisms, including pollinators, in areas 
adjacent to the treated site. Protect the forage and habitat of no n-target organisms by following label directions intended to minimize 
spray drift.

PRODUCT INFORMATION 
Wolverine® Advanced Herbicide is designed for broad spectrum postemer gence control of important grass and broadleaf weed species 
in wheat (including durum wheat) and barley. 
ENVIRONMENTAL AND BIOLOGICAL ACTIVITY 
Wolverine Advanced Herbicide is a postemergence herbicide and best results are obtained when applications are made to yo ung 
actively growing weeds. Wolverine Advanced Herbicide is primarily absorbed through the foliage and thorough spray coverage is 
important. 
CROPS 
Wolverine Advanced Herbicide may be used in wheat, including durum and barley. 
APPLICATION TIMING 
Wheat: Apply Wolverine Advanced Herbicide to the crop from emergence up to 60 days prior to harvest in the states of Minnesota, 
Montana, North Dakota, and South Dakota, 70 days prior to harvest in other states. 
Barley: Apply Wolverine Advanced Herbicide to the crop from emergence up to the 5-leaf stage. 
Weed Application Timing 
Grass Weeds: Wolverine Advanced Herbicide has no effect via the soil on grass weeds and will only control emerged grass weeds. 
Wolverine Advanced Herbicide when applied as directed will control the annual grass weeds listed in GRASS WEED CHART. 
Wolverine Advanced Herbicide will control susceptible grass weeds in the 1-leaf (fully expanded) to 2-tiller stage of growth. B lackgrass 
can be controlled over a wide range of growth stages, from the 1-leaf (fully expanded) through the advanced tillering stage. Wi ndgrass 
will be controlled from emergence to a height of 3 inches. 
Broadleaf Weeds: See BROADLEAF WEED CHART for a list of susceptible weed species and maximum stage of grow th at application 
for best results.

APPLICATION DOSAGE and METHODS 
Dosage 
One case will treat 20 acres at 1.7 pt/A. Do not use less than the 1.7 pt/A unless directed by a Bayer CropScience representative. 
 
Ground Application 
Properly calibrated ground application equipment may be used to apply Wolverine Advanced Herbicide postemergence as a foliar 
spray. Select spray nozzles that provide best spray distribution and weed coverage at the appropriate spray pressure. Ground sp eed 
for application should not exceed 10 mph. Avoid uneven spray distribution, skips, overlaps, and spray drift. 
 
Apply the appropriate dosage broadcast in 10 or more gallons of water per acre. Under conditions where large grass weeds or den se 
weed populations are present or adverse environmental conditions exist, a greater spray volume of 15 – 20 gallons of spray solution 
per acre is required for best weed control. DO NOT apply with hol low cone type nozzles or other nozzles that produce a fine dro plet 
spray. Use nozzles and spray pressure for ground application that de liver medium to coarse spray droplets as indicated in the n ozzle 
manufacturer’s catalogs such as 80 -degree or 110-degree flat-fan nozzles for optimum spray coverage and canopy penetration. Use 
screens that are 50 mesh or larger. 
Do not use flood-jet nozzles or cone nozzles. Nozzle types, nozzle spacings, and lower spray pressures that produce very coarse spray 
droplets may not provide adequate coverage of the weeds to ensure optimum control. 
Aerial Application 
Calibrate aerial (fixed wing or helicopter) sp ray equipment prior to use. Wolverine Advanced Herbicide should be applied in a m inimum 
spray volume of 5 gallons per acre if crop canopy and weed density allow adequate spray coverage. 
Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin. 
 
Restrictions 
x Handlers must use closed mixing loading systems during mixing/loading liquids for aerial applications to fallow land and high-
acreage field crops. 
x Aerial Application to fallow land is restricted within 25 feet of residential areas (e.g., homes, schools, playgrounds, shopping 
areas, hospitals, etc). 
 
SPRY DRIFT MANAGEMENT 
Mandatory Spray Drift Management 
Aerial Applications 
x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a 
greater application height is necessary for pilot safety. 
x Applicators are required to use a medium or coarser droplet size (ASABE S641). 
x Do not apply when wind speeds exceed 10 mph at the application site. 
x The boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of the rotor diameter 
for helicopters. 
x Applicators must use ½ swath displacement upwind at the downwind edge of the field. 
x Do not apply during temperature inversions. 
 
Ground Boom Applications 
x User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the 
ground or crop canopy. 
x Do not apply when wind speeds exceed 10 mph at the application site. 
x Do not apply during temperature inversions. 
x Applicators are required to use a medium or coarser droplet size (ASABE S572). 
 
SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
Importance Of Droplet Size 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying 
larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable 
environmental conditions.

6 
 
 
Controlling Droplet Size - Ground Boom 
x Volume - Increasing the spray volume so that larger drop lets are produced will reduce spray drift. Use the highest 
x practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher 
x flow rate. 
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and 
x droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce 
drift. 
Controlling Droplet Size - Aircraft 
Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles 
should be oriented parallel with the airflow in flight. 
 
Boom Height - Ground Boom 
For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
Release Height - Aircraft 
Higher release heights increase the potential for spray drift. 
 
Shielded Sprayers 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not 
interfering with the uniform deposition of the spray on the target area. 
 
Temperature And Humidity 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. 
 
Temperature Inversions 
Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with altitude 
and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or 
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. 
 
Wind 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to 
be familiar with local wind patterns and terrain that could affect spray drift. 
WEED RESISTANCE-MANAGEMENT 
For resistance management, please note that Wolverine Advanced Herbicide contains Group 1, Group 27, and Group 6 herbicides. Any 
weed population may contain plants naturally resistant to Group 1, Group 27, and Group 6 herbicides. The resistant individuals may 
dominate the weed population if these herbicides are used repeatedly in the same fields. Appropriate resistance-management 
strategies should be followed. 
To delay herbicide resistance take one or more of the following steps: 
x Rotate the use of Wolverine Advanced Herbicide or other Group 1, Group 27, and Group 6 herbicides within a growing season 
sequence or among growing seasons with different herbicide groups that control the same weeds in a field. 
x Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target 
weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as 
the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which 
active ingredient is currently less prone to resistance. 
x Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information 
related to herbicide use and crop rotation, and that considers tillage ( or other mechanical control methods), cultural ( e.g., 
higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological 
(weed-competitive crops or varieties) and other management practices. 
x Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possibl e 
herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; 
(3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed 
production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or 
tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving 
between fields, and planting clean seed.

7 
 
x If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to 
another management strategy or herbicide with a different mode of action, if available. 
x Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or 
integrated weed-management recommendations for specific crops and weed biotypes. 
x For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). 
You can also contact your pesticide distributor or university extension specialist to report resistance. 
 
WEED CONTROL DIRECTIONS 
Wolverine Advanced Herbicide is a postemergence herbicide and best results are obtained when applications are made to young 
actively growing weeds. Treat heavy weed infestations before they become competitive with the crop. Thorough coverage of weeds is 
necessary to obtain good weed control. 
Postemergence application of Wolverine Advanced Herbicide will control the following grass and broadleaf weeds. 
 
Grass Weed Chart 
Wolverine Advanced Herbicide will control susceptible grass weeds in the 1-leaf (fully expanded) to 2-tiller stage of growth. B lackgrass 
can be controlled over a wide range of growth stages, from t he 1-leaf (fully expanded) through the advanced tillering stage. Wi ndgrass 
will be controlled from emergence to a height of 3 inches. Applications should be made to young, vigorously growing weeds.

MOISTURE EFFECTS ON ANNUAL GRASS WEED CONTROL 
The following conditions will result in optimum wild oat control: 
1. Adequate soil moisture which occurs under normal ra infall in wheat or barley following a fallow year. 
2. Temperatures lower than 85 q F for several days prior to application. 
Low soil moisture levels, low humidity, and high temperatures pr ior, during or following application may reduce wild oat and fo xtail 
control provided by Wolverine Advanced Herbicide. 
Foxtail under drought stress will exhibit rolled leaves ("onion le af") and should not be sprayed as poor control may result. Ap ply 
Wolverine Advanced Herbicide when conditions improve.

Partially controlled weeds will be stunted in growth and/or be reduced in number as compared to 
non-treated areas and performance may not be commercially acceptable. Best results are 
obtained when weeds are treated with Wolverine Advanced Herbicide before they reach 4 inches 
in height. The degree of weed control will vary with weed size, density, coverage and growing 
conditions.

COMPATIBILITY TESTING AND TANK MIX PARTNERS 
 
Compatibility 
If Wolverine Advanced Herbicide is to be tank mixed with other pesticides, compatibility should be tested prior to mixing. To t est for 
compatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray, combining all ingredients in the same ratio as the 
anticipated use. If any indications of physical incompatibility develop, do not use this mixture for spraying. Indications of i ncompatibility 
usually will appear within 5-15 minutes after mixing. Read and foll ow the label of each tank-mix product used for precautionary 
statements, directions for use, geographic and other restrictions. 
Tank mixtures For Insect Control 
Wolverine Advanced Herbicide may be tank mixed with Baythroid® XL, Mustang Max™, or Warrior® insecticides providing proper timing 
for insect and weed control are the same. 
 
Tank mixtures For Disease Control 
Fungicides such as Stratego ®, Tilt®, Headline®, mancozeb (Dithane F-45 ®; Manzate® 75DF; Penncozeb® 75DF), or Topsin ® M may be 
tank mixed with Wolverine Advanced Herbicide when timing for application of each tank mix partner is the same for the use site. Do not 
apply Wolverine Advanced Herbicide in tank mixture with tebuconazole. 
Tank mix applications of herbicides with fungicides may cause te mporary yellowing, leaf burn and or height reduction of the crop. Refer 
to the specific fungicide label for use directions, application rates, restrictions and a list of diseases controlled. 
 
Order of Mixing 
Wolverine Advanced Herbicide must be applied with clean and properly calibrated equipment. Prior to adding Wolverine Advanced 
Herbicide to the spray tank, ensure that the spray tank, filters and nozzles have been thoroughly cleaned. In-line strainers an d nozzle 
screens should be 50 mesh or coarser. 
1. Fill the spray tank 1/4 to 1/2 full with clean water then add AMS or UAN and begin agitation or bypass. 
2. Add the appropriate rate of Wolverine Advanced Herbicide dire ctly to the spray tank. Maintain sufficient agitation during bo th 
mixing and application. 
3. Add a listed tank mix partner, if desired. 
4. Add surfactant if desired. 
5. Fill the spray tank with balance of water needed. 
6. Continue agitation during Wolverine Advanced Herbi cide application to ensure uniform spray coverage. 
 
Equipment Cleanup Procedures 
1. Drain the tank completely, and then wash out tank , boom and hoses with clean water. Drain again. 
2. Half fill the tank with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate of 1% (i.e., 1 g allon of 
domestic ammonia for every 100 gallons of rinsate). Complete fil ling of the tank with water. Agitate/recirculate and flush thro ugh 
boom and hoses. Leave agitation on for 10 minutes. Drain tank completely. 
3. Repeat step 2. 
4. Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and remove visible residues. 
5. Flush tank, boom, and hoses with clean water. 
6. Inspect tank for visible residues. If present, repeat step 2.

Where a crop is not specified, conduct a field bioassay as described in “FIELD BIOASSAY” section of this label. 
 
FIELD/SMALL SCALE BIOASSAY 
A field bioassay must be conducted for crops not listed on this label. To conduct a field bioassay, plant strips of the crop you want to 
grow the season following Wolverine Advanced Herbicide application. Monitor the crop for response to Wolverine Advanced Herbicide 
to determine if the crop can be grown safely in previously treated Wolverine Advanced Herbicide areas. Do not plant any rotational 
crops within 30 days following Wolverine Advanced Herbicide application. 
 
USE PRECAUTIONS 
x Do not apply to crops undersown with legume species. 
x Rainfall within 1 hour may result in reduced weed control. 
x Apply to actively growing weeds. Weed control may be reduced when weeds are under stress due to severe weather conditions, 
drought, very cold temperatures, etc. Weed control may be reduced if the herbicide applications are made under dry, dusty 
conditions – especially in the wheel track areas. Ground speed for application should not exceed 10 mph. 
x Tank mix applications of herbicides with fungicides may cause temporary yellowing, leaf burn and or height reduction of the crop.
