PRODUCT INFORMATION
Autumn Super 51 WDG Herbicide may be used for burndown of existing vegetation and
residual weed control when applied to no-till or conservation tillage fields anytime after the
fall harvest but prior to planting field corn or soybeans the following spring. Do not apply to
frozen ground. Weed growth ceases within hours after Autumn Super 51 WDG Herbicide
is applied. Symptoms progress from yellowing to necrosis resulting in eventual plant death
within 1-4 weeks after application.
Autumn Super 51 WDG Herbicide alone will not provide season-long preemergence control
of annual grass and broadleaf weeds but should be applied as the first herbicide in an
integrated weed control program that includes tank mixtures and/or in-season sequential
applications with additional herbicide products.
WEEDS CONTROLLED
Autumn Super 51 WDG Herbicide effectively controls a broad array of important grass and
broadleaf weeds when applied at rates of 0.3 to 0.5 ounces of product per acre in crop
stubble. For best control, broadleaf weeds should be no greater than 3 inches in height and
annual grasses no greater than 1 inch in height. Weeds controlled are listed below in Table 1:

HERBICIDE RESISTANCE MANAGEMENT (WSSA) RECOMMENDATIONS
For resistance management, Autumn Super 51 WDG Herbicide is a Group 2 herbicide.
Any weed population may contain or develop plants naturally resistant to Autumn Super
51 WDG Herbicide and other Group 2 herbicides. The resistant biotypes may dominate
the weed population if these herbicides are used repeatedly in the same field. Appropriate
resistance management strategies should be followed.
To delay herbicide resistance take one or more of the following steps:
• Rotate the use of Autumn Super 51 WDG Herbicide or other Group 2 herbicides within a
growing season sequence or among growing seasons with different herbicide groups that
control the same weeds in a field.
• 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.
• 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.
• Scout after herbicide application to monitor weed populations for early signs of resistance
development. Indicators of possible 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.
• 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.
• 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.
• 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.
ROTATIONAL CROP RESTRICTIONS
The following rotational crops (Table 2) may be planted after applying Autumn Super 51 WDG
at the directed rates. Planting earlier than the specified interval may result in crop injury. These
intervals are based on crops grown under favorable growing conditions. Crops grown under less
than favorable environmental conditions (drought, nutrient deficiencies, pest pressure, etc.) may
demonstrate reduced tolerance to crop protection products.
TABLE 2: ROTATIONAL CROP RESTRICTIONS
Crop Minimum Precipitation Requirement1 Minimum Plant Back Interval
Barley2 15 inches 9 months
Cotton2 15 inches 10 months
Corn (Yellow field corn, White field corn)2  1 month
Corn (sweet, popcorn)2,4 15 inches 9 months
Soybean2,3 2 months
Wheat (Spring)2 3 months
Wheat (Winter)2 3 months
All other crops4 30 inches 18 months
1 The amount of cumulative precipitation required before planting of a rotational crop is in addition to the required rotational interval given in months. Furrow or flood irrigation not to be
included in total. No more than 7 inches of overhead irrigation included in total.
2  Crop varieties planted back at intervals of one year or less should not have known acute sensitivity to ALS-inhibiting and/or SU herbicides.
3  When soil pH is 7.5 or above, soybean plant back should be delayed to the 9 month interval. If STS soybeans are to be planted on these soils, then the rotational interval is 4 months.
4  When soil pH is 7.5 or above, crop plant back is delayed to 18 months for crops listed in the 9-10 month interval, and to 24 months for crops listed in the 18 month interval.

OTHER CROPS
All other crops may be seeded only after the completion of a successful field bioassay after an
Autumn Super 51 WDG Herbicide application. Refer to the “Field Bioassay” section.
FIELD BIOASSAY
A field bioassay must be completed before rotating to crops other than those specified in the
“Rotational Crop Restrictions” section of this label. To conduct an effective field bioassay,
grow strips of the crop you intend to grow in the following season in a field previously treated
with Autumn Super 51 WDG Herbicide. The test strip should include low areas and knolls, and
include variations in soil such as type and pH. Crop response to the bioassay will determine if the
crop(s) grown in the test strips can be grown safely in the areas previously treated with Autumn
Super 51 WDG Herbicide.
SPRAY DRIFT MANAGEMENT
Autumn Super 51 WDG Herbicide is not volatile. Damage to sensitive crops can occur as a result
of spray drift. Spray drift can be managed by several application factors and by spraying under
appropriate climatic conditions. Consequently, avoidance of spray drift is the responsibility of the
applicator.
SPRAY DRIFT
Ground Boom Applications
• Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet
above the ground or crop canopy unless making a turf, pasture, or rangeland application, in
which case applicators may apply with a nozzle height no more than 4 feet above the ground.
• For applications prior to the emergence of crops and target weeds, applicators are required
to use a Coarse or coarser droplet size (ASABE S572.1).
• For all other applications, applicators are required to use a Medium or coarser droplet size
(ASABE S572.1).
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
SENSITIVE AREAS
The pesticide must only be applied when the potential for drift to adjacent sensitive areas (e.g.,
residential areas, bodies of water, known habitats for threatened or endangered species, non-
target crops) is minimal (e.g., when wind is blowing away from the sensitive areas).
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of
many equipment-and-weather-related factors determine the potential or spray drift. The applicator
and the grower are responsible for considering all these factors when making decisions.
Do not apply under circumstances where possible drift to unprotected persons or to food,
forage or other plantings that might be damaged or crops thereof rendered unfit for sale, use or
consumption can occur.
To avoid potential adverse effects to non-target areas, you must maintain a 25 foot buffer
between the point of direct application and the closest downwind edge of sensitive terrestrial
habitats (including grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas
and shrub lands), sensitive freshwater habitats (including lakes, rivers, sloughs, ponds, creeks,
marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
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 improperly, or under unfavorable environmental conditions (see Wind, Temperature and
Humidity, and Temperature inversions below).
Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles
and pressure that deliver COARSE spray droplets as indicated in nozzle manufacturer’s catalogs
and in accordance with ASAE Standard S-572.1. Nozzles that deliver COARSE spray droplets
help minimize spray drift. Spray volume per acre (GPA) must be adequate to maintain thorough
coverage of weeds.
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.
GROUND BOOM
Controlling Droplet Size
• Volume – Increasing the spray volume so that larger droplets are produced will reduce spray
drift. Use the highest practical spray volume for the application. If a greater spray volume is
needed, consider using a nozzle with a higher flow rate.
• Pressure – Use the lowest spray pressure recommended for the nozzle to produce the target
spray volume and droplet size.
• 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 air stream
produces larger droplets than other orientations and is the recommended practice. Significant
deflection from horizontal will reduce droplet size and increase drift potential.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider
using nozzles designed to reduce drift.
Boom Length
For some use patterns, reducing the effective boom length may further reduce drift without
reducing swath width.
Boom Height
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform
coverage. For ground equipment, the boom should remain level with the crop and have minimal
bounce.
Swath Adjustment
When applications are made with a crosswind, the swath will be displaced downwind. Therefore,
on the up and downwind edges of the field, the applicator must compensate for this displacement
by adjusting the path of the sprayer upwind. Swath adjustment distance should increase, with
increasing drift potential (higher wind, smaller drops, etc.).

234 mm
242 mm
3 5
150 mm
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.
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. Avoid applications
during temperature inversions.
Windblown Soil Particles Advisory
WINDBLOWN SOIL PARTICLES: Autumn Super 51 WDG Herbicide has the potential to move
off-site due to wind erosion. Soils that are subject to wind erosion usually have a high silt and/or
fine to very fine sand fractions and low organic matter content. Other factors which can affects
the movement of windblown soil include the intensity and direction of prevailing winds, vegetative
cover, site slope, rainfall, and drainage patterns. Avoid applying Autumn Super 51 WDG Herbicide
if prevailing local conditions may be expected to result in off-site movement.
APPLICATION INFORMATION
Autumn Super 51 WDG Herbicide may be applied by ground application only. Do not apply
Autumn Super 51 WDG Herbicide by air or through any type of irrigation system.
Autumn Super 51 WDG Herbicide may be applied as a broadcast treatment in a minimum of 10
gallons of water per acre. For weed control in dense weed populations, control of weeds under
adverse growing conditions, control of mature weeds or control of weeds in fields with heavy crop
residues remaining on the soil surface, use higher spray volumes from 15 to 30 gallons per acre.
Uniform, thorough spray coverage is important to achieve consistent weed control. Select
spray nozzles and pressure that deliver COARSE spray droplets as indicated in nozzle
manufacturer’s catalogs and in accordance with ASAE Standard S-572.1. Nozzles that
deliver COARSE spray droplets may be used to reduce spray drift provided spray volume
per acre (GPA) is increased to maintain coverage of weeds.
Do not use nozzles that produce FINE (e.g. – Cone) or EXTRA COARSE (e.g. – Flood jet)
spray droplets.
COMPATIBILITY
If Autumn Super 51 WDG Herbicide is to be tank-mixed with other pesticides not listed
specifically on this label, compatibility should be tested prior to mixing. To test for
compatibility, use a small container and mix a small amount (0.5 to 1qt) of spray, combining
all ingredients in the same ratio as the anticipated use. If any indications of physical
incompatibility develop (precipitation, settling, changes in color) do not use this mixture for
spraying. Indications of incompatibility may occur within 5-15 minutes after mixing. Read
and follow the label of each tank mix product used for precautionary statements, directions
for use, geographic and other restrictions.
MIXING INSTRUCTIONS
Autumn Super 51 WDG Herbicide must be applied with clean and properly calibrated
equipment. Prior to adding Autumn Super 51 WDG Herbicide, ensure that the spray tank,
filters and nozzles have been thoroughly cleaned.
1. Fill spray tank with 25% of the required volume of water, and begin agitation prior to the
addition of Autumn Super 51 WDG Herbicide.
2. Continue agitation to ensure full dispersion of Autumn Super 51 WDG Herbicide.
3. If Autumn Super 51 WDG Herbicide is applied in a tank mixture with other pesticides,
add Autumn Super 51 WDG Herbicide to the spray tank first and ensure it is thoroughly
dispersed before adding other pesticides.
4. Continue to fill the spray tank with water to the desired volume and agitate while adding
spray adjuvants and nitrogen fertilizers.
5. Continue agitation during application to ensure a uniform spray mixture. (If Autumn Super
51 WDG Herbicide is added to a partial tank of spray solution, pre-slurry Autumn Super
51 WDG Herbicide with clean water prior to adding to the spray tank).
If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS
go into the spray tank prior to Autumn Super 51 WDG Herbicide.
RE-SUSPENDING WDG PRODUCTS IN SPRAY SOLUTION
Like other water dispersible granules or suspension concentrates (SC’s), Autumn Super 51
WDG Herbicide will settle if left standing without agitation. If the spray solution is allowed
to settle for one hour or more, re-agitate the spray solution for a minimum of 10 minutes
before application.
SPRAY ADDITIVES
Autumn Super 51 WDG Herbicide is a water dispersible granule that requires the use of an
external adjuvant and nitrogen fertilizer.
• The addition of Crop Oil Concentrate (COC), Methylated Seed Oil (MSO) or equivalent oil
blend at 1% v/v (1 gallon per 100 gallons of final spray volume) is required.
• The addition of nitrogen fertilizer (28 or 32% Urea Ammonium Nitrate at 1.5-2 qts/A or
Spray Grade Ammonium Sulfate at 1.5-3.0 lb/A) is required.
TANK CLEANUP PROCEDURE
1. Drain the tank completely, then wash out tank, boom, and hoses with clean water. Drain again.
2. Fill the tank half full with clean water and add ammonia (i.e., 3% domestic ammonia
solution) at a dilution rate of 1% (i.e., 1 gallon of domestic ammonia for every 100 gallons
of rinsate). Completely fill the tank with water. Agitate/recirculate and flush through 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. Inspect tank for visible residues. If
present, repeat Step 2

SPECIFIC CROP USE DIRECTIONS AND RATES
Autumn Super 51 WDG Herbicide may be used for burndown control of existing vegetation
and residual weed control when applied to no-till or conservation tillage fields anytime
after the fall harvest and at least 30 days prior to planting field corn, white corn, and corn
grown for seed, 60 days prior to planting soybean and 90 days prior to planting wheat.
Use rates of Autumn Super 51 WDG Herbicide range from 0.3 to 0.5 oz./A and will vary
according to geographic location, application timing  and soil pH. For soybeans, if residual
ALS-containing products were applied the growing season before and are planned to be
applied in the spring following an Autumn Super application, it is recommended to plant
a STS soybean variety. Do not apply to frozen ground. Best results are obtained when
applications are made to actively growing weeds. Autumn Super 51 WDG Herbicide will
affect weeds that are larger than the listed height, however, speed of activity and control
may be reduced. Autumn Super 51 WDG Herbicide will provide short term residual of
small seeded broadleaf weeds.

USE RESTRICTIONS
1. Autumn Super 51 WDG Herbicide contains two active ingredients; Iodosulfuron and
Thiencarbazone-methyl. When Autumn Super 51 WDG Herbicide is used as a post-
harvest burndown application at the 0.5 oz/A (0.022 lb AIs/A) product rate, no additional
iodosulfuron active ingredient and 0.026 lb of additional Thiencarbazone-methyl may be
applied during the same 365 day period on the same acreage. No additional post-harvest
burndown application with Thiencarbazone-methyl is allowed.
2. DO NOT apply when wind causes drift to off-site vegetation, as injury may occur. Small
amounts of Autumn Super 51 WDG Herbicide delivered via drift or spray tank combinations
can damage other plants. Carefully manage spray drift and tank cleanout.
3. DO NOT apply this product by air or through any type of irrigation system.
4. For field corn, use as a post-harvest burndown application in the fall at least 30 days prior
to planting.
5. For soybeans, use as a post-harvest burndown application in the fall at least 60 days prior
to planting.
6. DO NOT graze livestock within 45 days of application of Autumn Super 51 WDG Herbicide.
7. A 25 foot buffer for ground applications must be maintained between the point of direct
application and the closest downwind edge of sensitive terrestrial habitats (including
grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrub
lands), sensitive freshwater habitats (including lakes, rivers, sloughs, ponds, creeks,
marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
USE PRECAUTIONS
1. Rainfall within 2 hours may result in reduced weed control. Established weeds should be
actively growing when the herbicide application is made. Weed control may be reduced if
application is made when weeds are dust covered or in the presence of heavy dew, fog, and
mist/rain or when weeds are under stress due to drought.
2. Apply Autumn Super 51 WDG Herbicide spray mixtures within 24 hours of mixing to avoid
product degradation.
3. Autumn Super 51 WDG Herbicide will not provide season-long preemergence control of
annual grass and broadleaf weeds. The length of residual weed control is generally rate
dependent with greater residual control with higher use rates.
4. Application of an ALS-containing herbicide during the growing season following an Autumn
Super 51 WDG Herbicide application may increase the injury potential to soybeans when
planted as the next rotational crop.  In situations where extreme dry and cold environmental
conditions follow a fall Autumn Super 51 WDG Herbicide application, it is recommended
to plant a STS soybean cultivar if one is using additional spring-applied ALS-containing
herbicides in soybeans.

grass and broadleaf weeds but should be  applied as the first herbicide in an integrated weed
control program that includes sequential applications including but not limited to, the following
herbicide products:
• For extended residual control in corn, follow Autumn Super 51 WDG Herbicide with sequential
programs based on targeted weeds. Such programs may include Balance® Flexx, Corvus®,
Capreno™ and Laudis®.
• For season long control in soybean, follow Autumn Super 51 WDG Herbicide with a sequential
program based on targeted weeds.
