PRODUCT INFORMATION
MAGISTER SC is a suspension concentrate formulation that acts by contact to provide rapid knockdown of mites and certain insects. MAGISTER SC provides control of eggs by contact and controls immature and adult mites by both contact and ingestion. In addition to mites, MAGISTER SC has proven fungicidal activity. MAGISTER SC is a METI (mitochondrial electron transport inhibitor) classified as IRAC
Group 21 and a FRAC Group 39.

RESISTANCE MANAGMENT
For Use as an Acaricide:
For resistance management, Magister SC contains a Group 21 acaricide. Any insect/mite population may contain individuals naturally resistant to Magister SC and other Group 21 acaricides. The resistant individuals may dominate the insect/mite population if this group of acaricides are used repeatedly in the same fields. Appropriate resistance-management strategies should be followed To delay acaricide resistance, take the following steps:
Rotate the use of Magister SC or other Group 21 acaricides within a growing season, or among growing seasons, with different groups that control the same pests. Use tank mixtures with acaricides 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):
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. Mixtures with components having the same IRAC mode of action classification are not recommended for insect resistance management. When using mixtures, consider any known cross-resistance issues between the individual components for the targeted pest(s). Mixtures become less effective if resistance is already developing to one or both active ingredients, but they may still provide pest management benefits. 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. Adopt an integrated pest management program (IPM) for acaricides 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. 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. 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. For further information or to report suspected resistance contact a Gowan Company representative.

For Use as a Fungicide:
For resistance management, Magister SC contains a Group 39 fungicide. Any fungal/bacterial population may contain individuals naturally resistant to Magister SC and other Group 39 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.

To delay fungicide/bactericide resistance, take one or more of the following steps: Rotate the use of Magister SC or other Group 39 fungicides within a growing season sequence with different groups that control the same pathogens. Use tank mixtures with fungicide/bactericides 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. Adopt an integrated disease management program for fungicide/bactericide 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. Where possible, make use of predictive disease models to effectively time fungicide/bactericide applications. Note that using predictive models alone is not sufficient to manage resistance. Monitor treated fungal/bacterial populations for resistance development. Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-management and/or IPM recommendations for specific crops and pathogens. For further information or to report suspected resistance contact a Gowan Company representative. You can also contact your pesticide distributor or university extension specialist to report resistance.

APPLICATION INSTRUCTIONS
Apply this product to the crops listed on this label. Apply as described in the mixing and application section below. Apply only for the sites, pests, and application methods described on this label. Apply by ground or air unless otherwise specified under the crop comments or on supplemental labeling supplied by Gowan Company.

FOLIAR SPRAY APPLICATIONS
Foliar applications may be made using properly calibrated ground sprayers. Thorough and uniform coverage of plants, with direct contact of the spray mixture to the target pests is required for satisfactory control. Apply MAGISTER SC in sufficient water to ensure thorough coverage of fruit and foliage. Applications can be made with low or high volume spray equipment; however, thorough coverage is required for optimum control. Do not apply where thorough coverage of plant is not possible. Applications made with less than thorough coverage may result in slower activity and/or less overall control from a single application than an application made with higher gallonages. See application volume directions by crop in the Application Directions table.

SPRAY DRIFT MANAGEMENT
Do not allow spray to drift from the application site and contact people, structures people occupy at any time and the associated property, parks and recreation areas, non-target crops, aquatic and wetland areas, woodlands, pastures, rangelands, or animals. For ground boom applications, apply with nozzle height no more than 4 feet above the ground or crop canopy and when wind speed is 10 mph or less at the application site as measured by an anemometer. Use medium or coarser spray according to ASAE 572 definition for standard nozzles or VMD for spinning atomizer nozzles.
For orchard/vineyard airblast applications, do not direct spray above trees/vines and turn off outward pointing nozzles at row ends and outer rows. Apply only when wind speed is 3 -10 mph at the application site as measured by an anemometer outside of the orchard/vineyard on the upwind side. The applicator also must use all other measures necessary to control drift.

MIXING INSTRUCTIONS
Shake well before using and agitate frequently while applying. If agitation is stopped for an extended period of time, the spray solution must be thoroughly re-mixed prior to further use. Maintain agitation during mixing. In general, no additives are necessary for effective use of MAGISTER SC. MAGISTER SC may be tank mixed with non-ionic surfactants.
