DIPPING OR IMMERSION TREATMENTS
Spear-T Liquid Concentrate is a biological insecticide and miticide that contains the peptide active ingredient GS-omega/kappa-Hxtx-Hv1a.It is for use on ornamental plants and edible crops as an effective means for controlling pests such as aphids, broad mites, spider mites, thrips and whiteflies, as well as psyllids and spotted-wing drosophila. Spear-T Liquid Concentrate is a contact insecticide that functions primarily as a central nervous system inhibitor of target pests infesting labeled crops. Spear-T Liquid Concentrate is mixed with water and applied as a foliar spray with ground equipment equipped with fine nozzles to minimize droplet size.
GENERAL USE INSTRUCTIONS
The active ingredient in Spear-T Liquid Concentrate largely acts through contact. Spear-T Liquid Concentrate has no systemic activity, therefore thorough coverage of infested plant parts is necessary for best performance. Small droplet size will improve coverage and penetration of the crop canopy. Use of a non-ionic or blended organo-silicone surfactant will also improve coverage.
Spear-T Liquid Concentrate is effective on immature and some adult stages of the listed insect and mite pests. Earlier or younger developmental stages should be considered more susceptible. Spear-T Liquid Concentrate is not effective on the egg stage. Careful scouting to detect infestations early is important for optimal results. Repeat applications at 3-10-day intervals (or at intervals necessary to maintain control) depending upon plant growth rate, pest activity and other factors.
Spear-T Liquid Concentrate may be applied up to and including the day of harvest (Pre-harvest interval = 0 days).
Spear-T Liquid Concentrate has been evaluated for phytotoxicity on a variety of edible and non-edible crops under various normal growing conditions. It is not feasible, however, to test all crop varieties in all mixtures and combinations. Therefore, prior to treating the entire crop, test a small portion of the crop for sensitivity.
Do not apply Spear-T Liquid Concentrate through any type of irrigation system.
For outdoor field use, do not apply more than 10 gallons per acre per year.
Integrated Pest Management (IPM):
Spear-T Liquid Concentrate is an important tool for sound pest management whenever pesticide use is necessary. Because the active ingredient has a novel mode of action, Spear-T Liquid Concentrate provides a new control method for the labelled pests. It effectively targets immature and some adult life stages. Based on sound scouting practices, use Spear-T Liquid Concentrate preventively to avoid infestations, as a spot spray to suppress localized infestations, or as a blanket spray to prevent outbreaks. Applying Spear-T Liquid Concentrate in rotation with other insecticides as a part of a resistance management program will reduce inputs of conventional insecticides and also delay development of pesticide resistance. Based on a variety of evaluations, Spear-T Liquid Concentrate is not disruptive to the benefits of biological control agents or other non-target species. It is not feasible, however, to test all species of beneficials in all situations. Therefore, consult with a pest control advisor, extension agent or the manufacturer before treating an entire crop where beneficial insects serve as part of an IPM program. Consult local agricultural authorities for IPM strategies that are specific to your crop and location.
Spear-T Liquid Concentrate contains the biological peptide GS-omega/kappa-Hxtx-Hv1a, which has a novel mode of action. It is classified as a Group 32 Insecticide and is not known to be cross-resistant to any other class of insecticide. Repeated use of any mode of action, however, has the potential for pests to develop insecticide resistance. To delay development of resistance, the following practices are recommended:
- Carefully follow the specific guidelines within the use directions.
- Avoid using the same active ingredient or mode of action on consecutive generations of insects. Multiple applications to reduce a single generation, however, are acceptable. Treat the next generation with a different mode of action.
- Avoid using less than labeled rates of any insecticide when applied alone.
- Target the insect early in development to achieve the greatest benefit from the insecticide.
- Consult local agricultural authorities for specific IPM strategies developed for your crop(s) and location.
DIPPING OR IMMERSION TREATMENTS
Spear-T Liquid Concentrate may be applied using a pre-plant dipping application to vegetative or hardwood unrooted cuttings and transplants for control of labeled pests. To prepare the dipping solution, thoroughly mix 1 gallon of Spear-T Liquid Concentrate with 3 gallons of water for a 25% product solution. If plant sensitivity is a concern, this concentration may be reduced to 1 gallon of Spear-T Liquid Concentrate with 9 gallons of water for a 10% solution. Prior to treating the entire crop, test a small portion of the crop for sensitivity. Use caution when dipping geranium, petunia and salvia cuttings because some cultivars may be sensitive.
For unrooted cuttings, place into the tank loose, or in a mesh bag or immersion tray with top. To maximize coverage, do not pack cuttings too tightly. Immerse the cuttings into the Spear-T Liquid Concentrate solution, and gently move the plants around for 5-10 seconds, or just long enough to completely wet all surfaces. Verify that there are no dry surface areas.
For bare-root transplants, hold by the roots and immerse in the Spear-T Liquid Concentrate solution. Gently move around for 5-10 seconds, or just long enough to completely wet all surfaces of the leaves and stems, but not the roots. Verify that there are no dry surface areas.
For plugs and liners, turn the tray upside down, when practical, and dip the plant tops (stems and foliage) into the Spear-T Liquid Concentrate solution. Gently move around for 5-10 seconds, or just long enough to wet all surfaces.
Once cuttings and transplants are removed from the dipping solution, plant into potting mix or soil in the usual manner. Allow treated plants to dry before misting or watering. Observe the following general guidelines:
- Clean and disinfect the dipping tank and equipment before a new dip solution is prepared.
- Prepare only as much dip solution as can be used in one day. Do not use dip solution for more than one day.
- Prior to treating a new crop, test a small number of plants for sensitivity. Immerse in dipping solution, plant into growing media, and observe over several days for plant damage. Do not use dipping if there is any visible damage to test plants.
- If plant pathogens are a concern, prepare a new dipping solution regularly.
- Submerge just long enough to wet all plant surfaces.
- Agitate dip solution throughout use.
- Do not immerse stressed or wilted cuttings or transplants.
