PRODUCT INFORMATION 
 
Apron MAXX RTA + Moly is a seed treatment fungicide that protects against damping-
off and seed rots due to Pythium, Phytophthora, Fusarium, Rhizoctonia spp., and early 
season Phytophthora root rot. Apron MAXX RTA + Moly also suppresses seed-borne 
Sclerotinia and Phomopsis spp. Apron MAXX RTA + Moly contains the active 
ingredient mefenoxam found in Apron XL
® that provides protection against Pythium and 
early season Phytophthora root rot. Apron MAXX RTA + Moly also contains the active 
ingredient fludioxonil found in Maxim® 4FS that provides protection against the 
remaining diseases mentioned in this label. 
 
 
RESISTANCE MANAGEMENT 
 
MEFENOXAM GROUP 4 FUNGICIDE 
FLUDIOXONIL GROUP 12 FUNGICIDE 
 
For resistance management, please note that Apron MAXX RTA + Moly contains Group 
4/ mefenoxam and Group 12/fludioxonil fungicides. Any fungal population may contain 
individuals naturally resistant to Apron MAXX RTA + Moly and other Group 4 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. 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 Apron MAXX RTA + Moly or other Group 4 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.

-8- 
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. 
 
Syngenta encourages responsible product stewardship to ensure effective long-term 
control of the fungal diseases on this label.

MIXING INSTRUCTIONS 
 
Apron MAXX RTA + Moly is especially formulated for on-farm treatment, using standard 
mechanical slurry or mist-type seed treatment equipment which accurately measures 
and mixes a flowable seed treatment. The equipment must provide uniform coverage of 
Apron MAXX RTA + Moly on the seed. Uneven seed coverage may not give the 
desired level of disease control. The product does not require the addition of water for 
application. Consult the manufacturer of the application equipment you plan to use for 
suitability for this application and for instructions on operation and calibration of the 
equipment. Do not mix Apron MAXX RTA + Moly fungicide with other pesticides unless 
sufficient compatibility, loading rates, and crop safety factors are determined. 
 
Apron MAXX RTA + Moly has been found to be compatible with some liquid inoculant 
products. Apron MAXX RTA + Moly may be mixed or applied sequentially with approved 
liquid inoculants. Consult the manufacturer of the liquid inoculants and a Syngenta 
Crop Protection seed treatment representative for directions before applying Apron 
MAXX RTA + Moly with liquid inoculants. 
 
Apron MAXX RTA + Moly contains an EPA-approved colorant that imparts an unnatural 
Blue color to the seed as required by the Federal Seed Act.

SEED CONTAINER LABEL REQUIREMENTS 
 
The Federal Seed Act requires that containers of treated seeds shall be labeled with the 
following statements: 
 
x This seed has been treated with mefenoxam and fludioxonil fungicides. 
x Do not use for feed, food, or oil purposes. 
 
In addition, the U.S. Environmental Protection Agency requires the following statements 
on containers of seeds treated with Apron MAXX RTA + Moly: 
 
x Groundwater Advisory: Mefenoxam is known to leach through soil into 
groundwater under certain conditions as a result of label use. Fludioxonil has 
properties and characteristics associated with chemicals detected in 
groundwater. These chemicals may leach into groundwater if used in areas 
where soils are permeable, particularly where the water table is shallow. 
x Excess treated seed may be used for ethanol production only if: (1) By-products 
are not used for livestock feed, and (2) No measurable residues of pesticide 
remain in the ethanol by-products that are used in agronomic practice. 
x Do not allow children, pets, or livestock to have access to treated seed. 
x Store away from feeds and foodstuffs. 
x Wear long-sleeved shirt, long pants and chemical-resistant gloves when handling 
treated seed. 
x Treated seeds exposed on soil surface may be hazardous to wildlife. Cover or 
collect treated seeds spilled during loading and planting. 
x Treated seed must be planted into the soil at a depth greater than 1 inch. 
x Dispose of all excess treated seed by burying away from bodies of water. 
x Do not contaminate water bodies when disposing of planting equipment 
washwaters. 
x Dispose of seed packaging in accordance with local requirements. 
x Based on the product label use rate and a default soybean seeding rate of 
250,000 seeds/A, each planting of this treated seed would result in 0.0063 lb 
mefenoxam/A and 0.0042 lb fludioxonil/A. 
x DO NOT apply more than 0.052 lb ai/Acre (23 g ai/Acre) per calendar year of 
mefenoxam- or metalaxyl-containing products as a seed treatment on Soybean.

CROP USE DIRECTIONS 
 
Soybean Seed Treatment 
 
Apron MAXX RTA + Moly provides protection against damping-off and seed rots due to 
Pythium, Phytophthora, Fusarium, Rhizoctonia spp., and early season Phytophthora 
root rot. Apron MAXX RTA + Moly also suppresses seed-borne Sclerotinia and 
Phomopsis spp. For these soybean diseases, Apron MAXX RTA + Moly is applied at 
the rate of 5.0 fl oz per 100 lb of seed. The specified Apron MAXX RTA + Moly rate 
delivers 3.75 grams active ingredient of mefenoxam and 2.5 grams active ingredient of 
fludioxonil per 100 kilograms of seed. If the target fields have a history of high 
Phytophthora pressure, then use 5.0 fl oz of Apron MAXX RTA + Moly with a tank mix of 
0.16-0.48 fl oz of Apron XL per 100 lb of seed. Read and follow all label directions and 
restrictions for Apron XL use. 
 
x Based on the product label use rate and a default soybean seeding rate of
