Product Information Diamir® TTZ Fungicide Seed Treatment is a liquid fungi- cide seed treatment that protects seed and seedlings from certain seedborne and soilborne diseases. Diamir TTZ will also suppress or control early season foliar diseases. See Table 1 for crop uses and diseases controlled or sup- pressed by Diamir TTZ. NOTE: When handling Diamir TTZ and when treating seed or while augering or handling treated seed, work in a well-ventilated area. Mode of Action Triticonazole, the active ingredient in Diamir TTZ, belongs to the Sterol Iosynthesis Inhibitors or Demethylation Inhibitors (DMI) class of chemistry, or target-site-of-action Group 3 fungicides. Resistance Management Due to the small amounts of Diamir TTZ applied to the seed that relocate to the upper parts of the plant, the potential for development of resistance is extremely low. Seed treatments of Diamir TTZ can, therefore, be followed by foliar use. Follow resistance management guidelines of foliar use fungicides containing triticonazole as specified on the respective labels. Application Instructions Diamir TTZ is for use in commercial seed treatment facili- ties. DO NOT use in on-farm systems. Seed must be of a good quality, well-conditioned, and free of chaff before treatment. Diamir TTZ contains an EPA-approved dye that imparts an unnatural color to the treated seed to prevent its acci- dental use as food or feed for animals. Refer to 21 CFR, Part 2.25. Prepare only the mixture of Diamir TTZ needed for imme- diate application to seed. Refer to the Tank Mixing Information section of this label. Apply Diamir TTZ at the rates listed in Table 1 and Table 2 as a water-based mix- ture using standard slurry or mist-type seed treatment application equipment. The exact amount of water needed to provide the mixture or slurry rate for uniform and com- plete coverage of the seed surface is difficult to predict because weather conditions, seed type and surface, and equipment used all have a bearing on coverage. Thorough seed coverage and proper application equipment calibra- tion are essential for good disease control. Consult a seed treatment specialist regarding slurry rates for the crop seed to be treated with Diamir TTZ and for calibration and operation procedures of the seed treatment equipment. Tank Mixing Information Tank Mix Partners When using Diamir TTZ in a tank mixture with other seed treatment products, follow all directions for use, crops/sites, use rates, dilution ratios, precautions, and limi- tations on the tank mix partner label. DO NOT exceed label dosage or application rate. The most restrictive label precautions and limitations must be followed. Diamir TTZ must not be mixed with any product that prohibits such mixing. Compatibility Test for Tank Mix Partners When tank mixing Diamir TTZ, always test compatibility before use by performing a jar test as follows:

  1. Add all intended seed treatment products and the appropriate amount of water in a clear glass container.
  2. Mix well and allow to sit for one hour.
  3. Remix and observe for incompatibility. Also test with the seed to ensure the combination of tank mix products does not have detrimental effects on the seed. Mixing Order
  4. Water - Add 3/4 of the required volume of water to the mix tank and turn on agitation.
  5. Agitation - Mechanical agitation is required for proper mixing of Diamir TTZ.
  6. Dye or colorant
  7. Wettable powders
  8. Soluble powders
  9. Flowable formulations (such as Diamir TTZ)
  10. Emulsifiable concentrates
  11. Water - Remaining 1/4 of required water volume is added last and can be used as rinsate for the chemical container or to adjust the total slurry to compensate for water displacement by powdered products. Maintain agitation until the entire slurry mixture has been used. Ensure seed is dry before bagging. Use Restrictions • DO NOT use treated seed for food, feed, or oil purposes. • DO NOT store treated seed near feed or foodstuffs. • DO NOT contaminate feed or foodstuffs. • DO NOT use the same auger for treating seed that will handle commercial or feed grains. • DO NOT contaminate domestic or irrigation waters. • DO NOT store leftover treated seed where it could be mixed with untreated seed. Store treated seed in cool, dry conditions. • DO NOT use in on-farm systems. 4

SEED CONTAINER LABEL REQUIREMENTS The Federal Seed Act requires that containers containing treated seeds shall be labeled with the following statements: “This seed has been treated with Diamir ® TTZ fungicide containing triticonazole. DO NOT use treated seed for food, feed or oil purposes.” The U.S. Environmental Protection Agency requires the following statements on containers containing seed treat- ed with triticonazole: “Store treated seed away from food and feedstuffs. DO NOT allow children, pets or livestock to have access to treated seed. Wear long pants, longsleeved shirt, shoes plus socks, and protective gloves when handling treated seed. Treated seed exposed on soil surfaces may be haz- ardous to wildlife. Plant treated seed into the soil to the recommended minimum depth or greater to minimize exposure. Cover or collect treated seed spilled during loading and planting, in particular at row ends and field corners. Dispose of all excess treated seed by burying seed away from bodies of water. DO NOT enter or allow worker entry into areas with treated seed during the restricted-entry interval (REI) of 12 hours with the exception that workers may enter these areas if there will be no worker contact with soil/media sub- surface. DO NOT contaminate bodies of water when disposing of planting equipment washwater. Dispose of seed packaging or containers in accor- dance with local requirements. 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 ethanol by-products that are used in agronomic practice. In the event of crop failure or harvest of a crop grown from this seed, the field may be replanted immediately with barley, buckwheat, corn, millet (pearl & proso), oats, popcorn, rye, sorghum, teosinte, triticale, wheat or any other crop for which a tolerance for triticonazole exists. For all other crops, the minimum plant back interval is 30 days from the date this seed was planted. A cover crop without a tolerance for triticonazole may be planted for purposes of erosion control or soil improvement; however, the crop must not be grazed or harvested for food or feed.” SEED CONTAINER LABEL REQUIREMENTS Export Only Federal law requires that containers of treated seed for export only must be labeled with the following information: “TREATED SEED: FOR EXPORT ONLY NOT FOR DOMESTIC SALE OR USE IN THE UNITED STATES. TREATED WITH THE FUNGICIDE TRITICONAZOLE.” 5
