vigor. Therefore, it is recommended to treat a quantity of seed using equipment similar to
that planned for treating the total seed lot. Then conduct germination tests with a portion of
this treated seed before committing the total seed lot to a selected seed treatment.
Due to seed quality, crop or variety sensitivity, and seed storage conditions beyond the
control of Syngenta, no claims are made to guarantee the germination of seed or propagating
material for any crop seed treated with A22353.
3.0 PRODUCT INFORMATION
A22353 is a broad-spectrum seed treatment for use only on soybean that consists of four
fungicide active ingredients: azoxystrobin, fludioxonil, sedaxane, and mefenoxam, as well as
one insecticide active ingredient: thiamethoxam. Each active ingredient has a different mode
of action. This seed treatment is recommended for control of many listed important fungal
plant diseases as well as listed early-season insect pests.
Azoxystrobin fungicide is active against Rhizoctonia and Pythium species, seed-borne white
mold (Sclerotinia sclerotiorum) as well as other listed seed-borne diseases causing decay,
damping-off and seedling blight.
Fludioxonil fungicide protects against damage from seed-borne and soil-borne disease
caused by Fusarium and Rhizoctonia species leading to seed decay, damping-off, and
seedling blight. This active ingredient also provides protection from seed-borne Diaporthe-
Phomopsis disease complex sometimes referred to as pod and stem blight (caused by
Phomopsis longicolla and Diaporthe phaseolorum). Fludioxonil also suppresses seed-borne
Sclerotinia.
Sedaxane fungicide protects against damage from seed decay, seedling blight, and damping-
off caused by Rhizoctonia species.
Mefenoxam fungicide provides protection against Pythium damping-off and early-season
Phytophthora.
Thiamethoxam protects against damage from listed insect pests.
3.1 Insecticide Resistance Management
A22353 contains thiamethoxam, a Group 4A insecticide. Thiamethoxam is a systemic
insecticide belonging to the neonicotinoid class of chemistry which includes nicotinic
acetylcholine receptor (nAChR) agonists.
THIAMETHOXAM GROUP
4A INSECTICIDE
A22353
Page 7
Insect populations may contain individuals naturally resistant to Group 4A insecticides and if
used repeatedly in the same fields, then resistant members may eventually dominate the
population. Because resistance development cannot be predicted, use sound resistance
management strategies established for the crop and use area.
Base seed treatment on an integrated pest management program that includes field
sanitation, historical information related to pesticide use, careful selection of pest-tolerant
crop varieties, scouting, and management practices which optimize populations of natural
enemies of insect pests such as within-field refuge (untreated areas). Sound management
programs also consider cultural and biological control practices.
In order to maintain susceptibility to these classes of chemistry:
x Use products at their full, specified doses.
x Use appropriate, well-maintained equipment. Use specified water volumes and apply at
optimal temperatures in order to obtain optimal treatment.
x When rate ranges are given, use the higher rate within the listed rate range when insect
pressure is expected to be high.
x Avoid using a single active ingredient or mode of action (same insecticide group)
exclusively for season long control of insect species with more than one generation per
crop season.
x For insect species with successive or overlapping generations, use a treatment window
approach. A treatment window is a period of time defined by the stage of crop
development and the biology of the pests of concern. Within the treatment window,
depending on the length of residual activity, single or consecutive applications may be
made using seed, in-furrow, or foliar treatments unless otherwise excluded by product
labels. Do not exceed the maximum amount of this insecticide’s mode of action allowed
per growing season.
x Following a treatment window of this insecticide’s mode of action, rotate to a treatment
window of effective products with a different mode of action before making additional
applications of this insecticide.
If resistance to this product develops in your area, this product or other products with a
similar mode of action may not provide adequate control. If poor performance cannot be
attributed to improper application or weather conditions, a resistant strain of insect may be
present. If you experience difficulty with control and resistance is a reasonable cause,
immediately consult your local company representative or agricultural advisor for the best
alternative method of control for the crop and use area.
Syngenta encourages responsible product stewardship to ensure effective long term control
of the insect pests on this label.

3.2 Fungicide Resistance Management
MEFENOXAM GROUP 4 FUNGICIDE
SEDAXANE GROUP 7 FUNGICIDE
AZOXYSTROBIN GROUP 11 FUNGICIDE
FLUDIOXONIL GROUP 12 FUNGICIDE
For resistance management, please note that A22353 contains Group 4/mefenoxam, Group
7/sedaxane, Group 11/azoxystrobin and Group 12/fludioxonil fungicides. Any fungal
population may contain individuals naturally resistant to A22353 and other Group 4, Group 7,
Group 11 or Group 12 fungicides. A gradual or total loss of pest control may occur over time
if these fungicides are used repeatedly in the same fields. Appropriate resistance-
management strategies should be followed.
Mefenoxam belongs to the phenylamide class of chemistry which interferes with fungal RNA
synthesis. Sedaxane is a succinate dehydrogenase inhibitor (SDHI) and belongs to the
carboxamide class of chemistry which disrupts cellular respiration and energy generation.
Azoxystrobin belongs to the strobilurin class of chemistry which disrupts cellular respiration
and energy generation. Fludioxonil belongs to the phenylpyrrole class of chemistry which
interferes with osmotic signal transduction.
To delay fungicide resistance, take one or more of the following steps:
x Rotate the use of A22353 or other Group 4, Group 7, Group 11 or Group 12 fungicides
within a growing season sequence with different groups that control the same pathogens.
x Use tank mixtures with fungicide from a different group that are equally effective on the
target pest when such use is permitted. Use at least the minimum application rate as
labeled by the manufacturer.
x Adopt an integrated disease management program for fungicide use that includes
scouting, uses historical information related to pesticide use, and crop rotation, and which
considers host plant resistance, impact of environmental conditions on disease
development, disease thresholds, as well as cultural, biological and other chemical control
practices.
x Where possible, make use of predictive disease models to effectively time fungicide
applications. Note that using predictive models alone is not sufficient to manage
resistance.
x Monitor treated fungal populations for resistance development.
x Contact your local extension specialist or certified crop advisor for any additional pesticide
resistance-management and/or IPM recommendations for specific crop and pathogens.
For further information or to report suspected resistance contact Syngenta at 1-866-
Syngent(a) (866-796-4368). You can also contact your pesticide distributor or university
extension specialist to report resistance.

Use should be based on an IRM program that includes field sanitation, scouting, historical
information related to pesticide use, and crop rotation. The IRM program should also
consider cultural, biological, and other chemical control practices.

4.0 APPLICATION DIRECTIONS
Important: Recirculate A22353 thoroughly before using.
Follow the manufacturer’s application instructions for the seed treatment equipment being
used.
Apply A22353 as a water-based slurry through standard liquid-type commercial seed
treatment equipment that provides uniform seed coverage. Seed treaters with atomizers or
spinning discs are highly recommended for better product coverage on the seed. Uneven or
incomplete seed coverage may not give the desired level of insect or disease control. The
minimum slurry volume to achieve adequate coverage is 4.0 fluid ounces of liquid slurry per
100 pounds of seed. More diluent may be required to obtain complete coverage. Thoroughly
mix the specified amount of A22353 into the required amount of water or liquid inoculant for
the slurry treater and dilution rate to be used.
Continuous agitation or mixing of the slurry mixture is necessary to prevent settling out of the
solution. Clean out any unused product from the treater after treating or maintain constant
agitation if the leftover slurry will be maintained overnight.
x Allow seed to dry before bagging.
4.1 Tank Mixtures
A22353 mixes easily with water and other water-based seed treatments manufactured by
Syngenta and many other companies. When mixing with products from other manufacturers,
test the compatibility prior to use by conducting a jar test: mix all intended seed treatments
with a proportional amount of water to achieve the desired slurry mixture in a clear glass
container. Mix well and allow mixture to sit for one hour. Remix and observe for
incompatibility.
A22353
Page 10
Mixing A22353 with tank-mix partners: Add ½ of the required water to the mix tank and turn
on the agitation. Mechanical agitation is preferred. If using wettable powders, add them first
to clean water allowing them to completely disperse prior to adding A22353 or other products.
Allow each tank-mix partner to completely disperse before adding the next product. Add the
remaining amount of water and agitate. Maintain agitation until the entire slurry mixture has
been used.
It is the pesticide user’s responsibility to ensure that all products are registered for the
intended use. Read and follow the applicable restrictions and limitations and directions for
use on all product labels involved in tank mixing. Users must follow the most restrictive
directions for use and precautionary statements of each product in the tank mixture.
