SpinTor 2SC is a Naturalyte insect control product for control or suppression of many foliage feeding pests including lepidoptera larvae (worms or caterpillars), Colorado potato beetles, leafminers and thrips infesting labeled crops. This product’s active ingredient, spinosad, is biologically derived from the fermentation of Saccharopolyspora spinosa, a naturally occurring soil organism. SpinTor 2SC should be mixed with water and applied as a foliar spray with aerial or ground equipment equipped for conventional insecticide spraying.
General Use Precautions
Integrated Pest Management (IPM) Programs
SpinTor 2SC is recommended for IPM programs in labeled crops. SpinTor 2SC should be applied when field scouting indicates target pest densities have reached the economic threshold, i.e., the point at which the insect population must be reduced to avoid economic losses beyond the cost of control. Other than reducing the target pest species as a food source, SpinTor 2SC does not have a significant impact on certain parasitic insects or the natural predaceous arthropod complex in treated crops, including big-eyed bugs, ladybird beetles, flower bugs, lacewings, minute pirate bugs, damsel bugs, assassin bugs, predatory mites or spiders. The feeding activities of these beneficials will aid in natural control of other insects and reduce the likelihood of secondary pest outbreaks. If SpinTor 2SC is tank mixed with any insecticide that reduces its selectivity in preserving beneficial predatory insects, the full benefit of SpinTor 2SC in an IPM program may be reduced.
Insecticide Resistance Management (IRM)
SpinTor 2SC contains spinosad, a Group 5 insecticide. Insect/mite biotypes with acquired resistance to Group 5 insecticides may eventually dominate the insect/mite population if Group 5 insecticides are used repeatedly in the same field or area, or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by SpinTor 2SC or other Group 5 insecticides. Currently, only spinetoram and spinosad active ingredients are classified as Group 5 insecticides. These two insecticide active ingredients share a common mode of action and must not be rotated with each other for control of pests listed on the label. Spinetoram and spinosad may be rotated with all other labeled insecticide active ingredients.
Do not apply SpinTor 2SC in greenhouses or other enclosed structures used for growing crops.
Proper application techniques help ensure thorough spray coverage and correct dosage for optimum insect control. The following directions are provided for ground and aerial application of SpinTor 2SC. Attention should be given to sprayer speed and calibration, wind speed, and foliar canopy to ensure adequate spray coverage.
Row Crop Application
Use calibrated power-operated ground spray equipment capable of providing uniform coverage of the target crop. Orient the boom and nozzles to obtain uniform crop coverage. A minimum of 5 to 10 gallons per acre should be utilized, increasing volume with crop size and/or pest pressure. Use hollow cone, twin jet flat fan nozzles or other insecticide atomizer suitable for insecticide spraying to provide a fine to coarse spray quality (per ASABE S-572, see nozzle catalogs). Under certain conditions, drop nozzles may be required to obtain complete coverage of plant surfaces. Follow manufacturer’s specifications for ideal nozzle spacing and spray pressure. Minimize boom height to optimize uniformity of coverage and maximize deposition (optimize on-target deposition) to reduce drift.
Orchard Spraying Application
Dilute Spray Application: This application method is based upon the premise that all plant parts are thoroughly wetted, to the point of runoff, with spray solution. To determine the number of gallons of dilute spray required per acre, contact your state agricultural experiment station, certified pest control advisor, or extension specialist for assistance.
Concentrate Spray Application: This application method is based upon the premise that all the plant parts are uniformly covered with spray solution but not to the point of runoff as with a dilute spray. Instead, a lower spray volume is used to deliver the same application rate per acre as used for the dilute spray.
Apply in spray volume of 5 gallons or more per acre (10 gallons or more per acre for trees, vines or orchard crops). Nozzle configuration should provide a medium to fine dropsize per ASABE S-572 standard (see USDA-ARS or NAAA handbook). Guidance for ASABE S-572 nozzle configuration can be found at the following web site: www.cpproductsinc.com. Boom length must be less than 75% of wing or 85% of rotor span and swath adjustment (offset) to compensate for crosswinds. Observe minimum safe application height (maximum 12 feet for ag canopies). Use GPS equipment, swath markers or flagging to ensure proper application to the target area. The boom nozzle configurations used should be patterned (e.g., at NAAA Fly-In) for both crosswind and near parallel winds. If application is made parallel to the wind direction, swath width should be adjusted downward. Use swath adjustment (offset) to compensate for crosswinds. Do not apply under completely calm wind conditions. It is best to apply when wind speed is between 2 to 10 mph. Under conditions of low humidity and high temperatures, adjust spray volume and droplet size upward to compensate for evaporation of spray droplets. Insect control by aerial application may be less than control by ground application because of reduced coverage.
Additional Use Restrictions for Certain Florida Counties to Manage Resistance Development in Western Flower Thrips (For Distribution and Use Only Within the State of Florida)
Directions for Use
SpinTor 2SC is only to be applied in certain geographical areas of the state. This product is not to be used in Broward County. This product is also prohibited from use in Palm Beach County east of the Arthur R. Marshall Loxahatchee Wildlife Refuge areas 1 and 2 or east, northeast, or north of the L-8 Canal north of the Arthur R. Marshall Loxahatchee Wildlife Refuge.
Application Timing: For determining when to treat, scout with enough regularity to monitor the population size. Base your application timing upon local thresholds. Consult your Dow AgroSciences representative, extension specialist, certified crop advisor or your state agricultural experiment station for any additional local use recommendations for your area.
Application Rate: Apply as a foliar spray at the rate indicated for thrips in enough spray volume to get thorough coverage. Use application equipment suitable for insecticide spraying for this crop. Use a higher rate in the rate range for heavier infestations. Thorough coverage is required for optimum efficacy. Prolonged or heavy infestations may require repeat applications. Suppression of thrips may be improved by addition of an adjuvant approved for growing crops to the spray mixture.
Specific Use Restrictions:
- Preharvest Interval: Do not apply within 10 days of harvest.
- Do not apply more than a total of 29 fl oz of SpinTor 2SC (0.45 lb ai spinosad) per acre per growing season.
- Chemigation: Do not apply this product to ginkgo through any type of irrigation system.
- Do not make more than 2 consecutive applications of Group 5 insecticides (spinetoram and spinosad). If additional treatments are required after 2 consecutive applications of Group 5 insecticides, rotate to another class of effective insecticides for at least 2 applications.
- Do not harvest plants for food or feed for at least one year after treatment.
Note: This product is toxic to bees exposed to treatment for 3 hours following treatment and toxic to aquatic invertebrates. Refer to the Environmental Hazards section of the product label attached to the product container for required protective measures.
