+ 
+PRODUCT INFORMATION 
+ 
+A21185B is a seed treatment product containing one insecticide active 
+ingredient (thiamethoxam), three fungicide active ingredients (difenoconazole, 
+mefenoxam, and sedaxane) and three plant-growth regulators (cytokinin, indole butyric 
+acid and giberellic acid). A21185B seed treatment protects against damage from 
+certain early-season insects and certain seed- and soil-borne diseases of cereal crops. 
+ 
+Difenoconazole provides protection against several seed, seedling and certain foliar 
+disease including bunts and smuts. Mefenoxam protects against damping-off caused by 
+Pythium spp. 
+ Sedaxane protects against Rhizoctonia spp. and loose smuts (Ustilago 
+spp.). 
+ 
+Thiamethoxam is a systemic seed treatment insecticide belonging to the neoticotinoid 
+class of chemistry. Thiamethoxam in A211 85B protects against aphids, wireworm and 
+European chafer. 
+ 
+A21185B contains the plant-growth regulators cytokinin, gibberellic acid and indolebutyric 
+acid to aid in enhanced germination and early season root and top growth. 
+ 
+Resistance Management 
+ 
+For resistance management, A21185B contains a Group 4A/thiamethoxam insecticide. 
+Any insect population may contain individuals naturally resistant to A21185B 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. 
+ 
+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 or
+
+A21185B 
+Page 7 
+pathogen 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 your area. 
+ 
+ 
+In order to maintain susceptibility to this class of chemistry: 
+x Avoid using Group 4A insecticides 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, apply A21185B and 
+other Group 4A insecticides using a “treatment window” approach. A treatment 
+window is a period of time as defined by the stage of crop development and/or the 
+biology of the pests of concern. Within the treatment window, depending on the 
+length of residual activity, there may either be single or consecutive applications 
+(seed treatment, soil, foliar, unless otherwise stated) of the Group 4A insecticides. 
+Do not exceed the maximum A21185B allowed per calendar year. 
+x Following a treatment window of Group 4A insecticides, rotate to a treatment window 
+of effective products with a different mode of action before making additional 
+applications of Group 4A insecticides. 
+x A treatment window rotation, along with other IPM practices for the crop and use 
+area, is considered an effective strategy for preventing or delaying a pest’s ability to 
+develop resistance to this class of chemistry. 
+x If resistance is suspected, do not reapply A21185B or any other Group 4A 
+insecticides. 
+ 
+Other Insect Resistance Management (IRM) practices include: 
+ƒ Incorporating IPM techniques into your insect control program. 
+ƒ Monitoring treated insect populations for loss of field efficacy. 
+ƒ Using tank-mixtures or premixes with inse cticides from a different target site of 
+action group as long as the involved products are all registered for the same crop 
+and effective rates are applied. 
+ 
+For additional information on Insect Resistance Management: 
+ƒ Contact your local extension specialist, certified crop advisor and/or product 
+manufacturer for additional insect resistance management recommendations. 
+ƒ Visit the Insecticide Resistance Action Committee (IRAC) on the web at: 
+http://www.irac-online.org 
+ 
+Syngenta encourages responsible product stewardship to ensure effective long-term 
+control of the insects on this label. 
+ 
+ 
+For resistance management, please note that A21185B contains a Group 
+3/difenoconazole, Group 4/mefenoxam, and Group 7/sedaxane fungicide. Any fungal 
+population may contain individuals naturally resistant to A21185B and other Group 3, 
+Group 4, or Group 7 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.
+
+A21185B 
+Page 8 
+Difenoconazole belongs to the triazole class of chemistry and is a demethylation 
+inhibitor of sterol biosynthesis (DMI). DMI’s disrupt membrane synthesis by blocking 
+demethylation. Mefenoxam is a systemic fungicide belonging to the phenylamide class 
+of chemistry which adversely affects fungal RNA synthesis. Sedaxane belongs to the 
+carboxamide class of chemistry and is a succinate dehydrogenase inhibitor (SDHI). 
+SDHI’s inhibit fungal metabolism by binding to the succinate dehydrogenase enzyme 
+thereby disrupting cellular respiration and energy generation. 
+ 
+To delay fungicide resistance, take one or more of the following steps: 
+ 
+x Rotate the use of A21185B or other Grou p 3, Group 4, or Group 7 fungicides 
+within a growing season sequence with different groups that control the same 
+pathogens. 
+ 
+x Use tank mixtures with fung icides 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 predicti ve disease models to effectively time 
+fungicide application. 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 
+crops 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 
+ 
+ 
+Important: Always re-circulate A21185B thoroughly before using. 
+ 
+Apply A21185B 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 and disease control. 
+ 
+A21185B may be applied in tank mixes or sequentially with other EPA-registered seed 
+treatment pesticide products. If using A21185B in a tank mixture with other seed 
+treatment products, observe all directions for use, crops/sites, use rates, dilution ratios, 
+precautions, and limitations which appear on the tank-mix partner label(s). 
+ 
+It is the pesticide user's responsibility to ensure that all products in the listed mixtures are 
+registered for the intended use. Users must follow the most restrictive directions are 
+precautionary language of the products of the mixture (for example, first aid from one 
+product, spray drift management from another).
+ 
+ 
+Consult the manufacturer of the application e quipment you plan to employ for suitability 
+for this application and for instructions on operation and calibration of the equipment. 
+Follow the manufacturer application instructions for the seed treatment equipment being 
+used. 
+ 
+Continuous agitation or mixing of the slurry mixture is necessary to prevent settling out of 
+the solution. 
+ 
+Allow seed to dry before bagging. 
+ 
+Follow planter manufacturer specifications for use of talc or other hopper box additives at 
+planting. Seed must be completely dry before adding to planter. 
+ 
+A21185B contains an EPA-approved dye/colorant that imparts an unnatural color to the 
+seed as required by the Federal Seed Act.
+

+ 
+SEED BAG LABEL REQUIREMENTS 
+ 
+The Federal Seed Act requires that bags containing treated seeds shall be labeled with 
+the following statements: 
+x This seed has been treated with difenoconazole, mefenoxam and sedaxane 
+fungicides, thiamethoxam insecticide, and cytokinin, indole butyric acid and 
+gibberellic acid plant growth regulators. 
+x Do not use for feed, food, or oil purposes. 
+ 
+In addition, the U.S. Environmental Protection Agency requires the following statements 
+on bags containing seeds treated with A21185B: 
+x Pollinator Precaution: Thiamethoxam is highly toxic to bees, and effects are 
+possible as a result of exposure to translocated residues in blooming crops. 
+x Groundwater Advisory: 
+Mefenoxam is known to leach through soil into ground water under certain 
+conditions as a result of agricultural use. Use of this chemical in areas where 
+soils are permeable, particularly where the water table is shallow, may lead to 
+groundwater contamination.
+ Thiamethoxam has properties and characteristics 
+associated with chemicals detected in ground water. These chemicals may 
+leach into the ground water if used in areas where soils are permeable, 
+particularly where the water table is shallow. 
+x Store away from feeds and foodstuffs. 
+x Wear long-sleeved shirt, shoes, 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. 
+x Do not allow children, pets, or livest ock to have access to treated seed. 
+x Dispose of all excess treated seed. Leftover treated seed may be doublesown 
+around the headland or buried away from water sources in accordance with local 
+requirements. 
+x Do not contaminate water bodies when disposing of planting equipment wash 
+waters. 
+x Dispose of seed packaging in accordance with local requirements. 
+x Treated seed must be planted into the soil at a depth greater than 0.5 inch.
