PRODUCT INFORMATION
Preemptor SC Fungicide is a broad-spectrum fungicide for the control of certain diseases in corn (field corn and field corn grown for seed), soybean and wheat. Preemptor SC Fungicide works by interfering with respiration and sterol synthesis in plant-pathogenic fungi, and is a potent inhibitor of spore germination and mycelial growth. The active ingredients, fluoxastrobin and flutriafol move rapidly into green tissue via translaminar movement. Preemptor SC Fungicide is rainfast 2 hours after application. Disease control will be reduced if rainfall occurs within 2 hours of application. The activity of Preemptor SC Fungicide makes it an excellent choice as a broad spectrum, dual action fungicide for disease management programs for corn, soybean and wheat. Other labeled fungicides can be used in tank mixture or alternated with Preemptor SC Fungicide to fulfill total disease management in corn (field corn and field corn grown for seed), soybean and wheat.

CROP ROTATION
Crops treated with Preemptor SC Fungicide may be rotated to corn, soybeans, peanuts or wheat at any time; sugar beets may be planted 30 days after treatment; and sweet corn and cotton may be planted 180 days after treatment. Rotation to any other crop not listed is prohibited.

RESISTANCE MANAGEMENT
The active ingredients in Preemptor SC Fungicide (fluoxastrobin and flutriafol) belong to the strobilurin (Group 11 Fungicides) and the
demethylation inhibitor (Group 3 Fungicides) fungicide classes, respectively. The dual action of Preemptor SC Fungicide results in a built in resistance management strategy that will minimize the resistance in at risk pathogens. Fungal pathogens are known to develop resistance to products with the same mode of action when used repeatedly. Because resistance development cannot be predicted, the use of this product should conform to resistance management strategies established for agricultural uses. Such strategies may include rotating and/or tank mixing with products having different modes of action, or limiting the total number of applications per year. FMC Corporation encourages responsible resistance management to ensure effective long-term control of
the fungal diseases on this label. In programs in which Preemptor SC Fungicide is used, the number of Group 11 fungicides (strobilurins) and Group 3 fungicides (demethylation inhibitors) applications should be no more than one half of the total number of fungicide applications per year for at risk pathogens. Follow specific directions for individual crops that limit the total number of applications.

APPLICATION GUIDELINES
Broadcast Ground Sprayers
Thorough coverage is necessary to provide good disease control. Applications using sufficient water volume to provide thorough and uniform coverage generally provide the most effective disease control. For ground application equipment 10 gallons/A minimum is required. Equip sprayers with nozzles that provide accurate and uniform application. Be certain that nozzles are the same size and uniformly spaced across the boom. Calibrate the sprayer before use. Use a pump with the capacity to: (1) maintain a minimum of 35 psi at nozzles, and (2) provide sufficient agitation in the tank to keep the mixture in suspension (this requires recirculation of 10% of the tank volume per minute). Use jet agitators or a liquid sparge tube for vigorous agitation. Use screens to protect the pump and to prevent nozzles from clogging. Screens placed on the suction side of the pump should be 16-mesh or coarser. Do not place a screen in the recirculation line. Use 50-mesh screens at the nozzles. Check nozzle manufacturer’s recommendations. For information on spray equipment and calibration, consult sprayer manufacturer’s and/or state recommendations. For specific local directions and spray schedules, consult the current state agricultural experiment station recommendations.

Aerial Application
For aerial application, use aircraft spray equipment in a minimum of 2 gallons of spray solution per acre for corn, soybean and wheat. Avoid application under conditions when uniform coverage cannot be obtained or when excessive spray drift may occur. Do not apply directly to humans or animals. Aerial applications made to dense canopies may not provide sufficient coverage of lower leaves to provide proper disease control.

Mixing Procedures
Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this product. Agitation is necessary for proper dispersal of the product. Maintain maximum agitation throughout the spraying operation. Do not let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.
