PRODUCT INFORMATION 
 
A20903A is a seed treatment product containing the active ingredients: Fludioxonil and 
Sedaxane fungicides and Thiamethoxam insecticide. A20903A protects against damage 
from listed early-season insects and seed-borne and seedling diseases of cereals. 
 
Fludioxonil fungicide is active against Fusarium and Rhizoctonia species. 
 
Sedaxane fungicide is active against seed decay, seedling blight and damping-off 
caused by Rhizoctonia species and listed loose smut diseases on cereals (Ustilago 
nuda and Ustilago tritici). 
 
Thiamethoxam is a systemic seed treatment insecticide belonging to the neonicotinoid 
class of chemistry. Thiamethoxam protects against listed chewing and sucking insects 
through contact and ingestion. 
 
 
RESISTANCE MANAGEMENT 
 
THIAMETHOXAM GROUP 4A INSECTICIDE 
 
For resistance management, A20903A contains a Group 4A/thiamethoxam insecticide. 
Any insect population may contain individuals naturally resistant to A20903A and other 
Group 4A insecticides. The resistant individuals may dominate the insect population if 
this group of insecticides are used repeatedly in the same fields. Appropriate 
resistance-management strategies should be followed. 
 
Thiamethoxam is a systemic insecticide belonging to the neonicotinoid class of 
chemistry which includes nicotinic acetylcholine receptor (nAChR) agonists. 
 
To delay insecticide resistance, take the following steps: 
 
x Rotate the use of A20903A or other Group 4A insecticides within a growing 
season, or among growing seasons, with different groups that control the same 
pests.

A20903A 
Page 7 
x Use tank mixtures with insecticides from a different group that are equally 
effective on the target pest when such use is permitted. Do not rely on the same 
mixture repeatedly for the same pest population. Consider any known cross-
resistance issues (for the targeted pests) between the individual components of a 
mixture. In addition, consider the following recommendations provided by the 
Insecticide Resistance Action Committee (IRAC): 
o Individual insecticides selected for use in mixtures should be highly 
effective and be applied at the rates at which they are individually 
registered for use against the target species. 
o Mixtures with components having the same IRAC mode of action 
classification are not recommended for insect resistance management. 
o When using mixtures, consider any known cross-resistance issues 
between the individual components for the targeted pest(s). 
o Mixtures become less effective if resistance is already developing to one 
or both active ingredients, but they may still provide pest management 
benefits. 
o The insect resistance management benefits of an insecticide mixture are 
greatest if the two components have similar periods of residual insecticidal 
activity. Mixtures of insecticides with unequal periods of residual 
insecticide activity may offer an insect resistance management benefit 
only for the period where both insecticides are active. 
x Adopt an integrated pest management program for insecticide use that includes 
scouting, uses historical information related to pesticide use, crop rotation, record 
keeping, and which considers cultural, biological and other chemical control 
practices. 
x Monitor after application for unexpected target pest survival. If the level of 
survival suggests the presence of resistance, consult with your local university 
specialist or certified pest control advisor. 
x Contact your local extension specialist or certified crop advisors for any 
additional pesticide resistance-management and/or IPM recommendations for 
the specific site and pest problems in your area.

SEDAXANE GROUP 7 FUNGICIDE 
FLUDIOXONIL GROUP 12 FUNGICIDE 
 
For resistance management, please note that A20903A contains both a Group 
7/sedaxane and Group 12/fludioxonil fungicide. Any fungal population may contain 
individuals naturally resistant to A20903A and other Group 7 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. 
 
Sedaxane is a succinate dehydrogenase inhibitor (SDHI) and belongs to the 
carboxamide 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 A20903A or other Group 7 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/insecticide 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/insecticide applications. Note that using predictive models alone is not 
sufficient to manage resistance. 
x Monitor treated fungal/insect 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. 
x 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.

MIXING PROCEDURES 
 
Important: Always re-circulate A20903A thoroughly before using. 
 
Follow the manufacturer’s application instructions for the seed treatment equipment 
being used. 
 
Apply A20903A as a water-based slurry utilizing standard slurry seed treatment 
equipment which provides uniform seed coverage. Uneven or incomplete seed 
coverage may not give the desired level of insect or disease control. Thoroughly mix the 
specified amount of A20903A into the required amount of water or liquid inoculant for 
the slurry treater and dilution rate to be used. 
 
Certain crops require addition of inoculants when the seed is treated or planted. 
A20903A is compatible with several liquid inoculant products. Consult the maker of the 
inoculant product and a Syngenta representative for directions before applying 
A20903A with inoculants.

A20903A 
Page 10 
The total application volume must be sufficient to provide desired level of coverage. 
Dilution is typically done with water or liquid inoculants. 
 
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. 
 
Required Dye Statement: Seed treated with this product must be visually identifiable 
from untreated seed by the use of an approved colorant or dye to prevent accidental 
use of treated seed as food for humans or feed for animals. Refer to 21 CFR, Part 2.25. 
Any colorant or dye added to treated seed must be cleared for use in accordance with 
40 CFR, Part 153.155(c). 
Allow seed to dry before bagging.
