Description
Target Pest: thrips, whiteflies, two spotted spider mites and broad mites
: Spear-T is a bioinsecticide for treatment of thrips, whiteflies, two spotted spider mites and broad mites in vegetables and ornamentals in greenhouses. Field trials of Spear-T demonstrate that results are equivalent or superior to conventional control chemicals.
Spear-T Liquid Concentrate is a biological insecticide containing the active ingredient GS-omega/kappa- Hxtx-Hv1a for use on ornamental plants, turf and edible crops against thrips, two-spotted spider mites, whiteflies, and broad mites. Spear-T Liquid Concentrate 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 for conventional insecticide spraying). Spear-T Liquid Concentrate is designed for greenhouse use.
Use in Biological Control: Spear-T Liquid Concentrate is a highly selective insecticide for use against the listed insect pest. Close scouting and early attention to infestations is highly recommended. Proper timing of application targeting newly hatched larvae is important for optimal results. Spear-T Liquid Concentrate is not effective on the egg stage.
Thorough coverage of infested plant parts is necessary. Spear-T Liquid Concentrate does not have systemic activity. Repeat applications at 3-10 day intervals depending upon plant growth rate, insect activity, and other factors. Tank miwith contact insecticides/miticides to enhance performance. Refer to tank misection. For hard-to-wet crops, consider using a spreader/sticker or an adjuvant that has been approved for targeted crop use to enhance the adhesion of Spear-T Liquid Concentrate to the crop. Examples of appropriate spreader/stickers or adjuvants are: 1) vegetable oils and 2) crop oils. Spear-T Liquid Concentrate has been evaluated for phytotoxicity on a variety of crops under various normal growing conditions. However, testing all crop varieties in all mixtures and combinations is not feasible. Prior to treating entire crop, test a small portion of the crop for sensitivity.
IPM: Spear-T Liquid Concentrate is an important tool in sound insect management whenever insecticide use is necessary. Apply Spear-T Liquid Concentrate alone or in combination and/or rotation with chemical insecticides. This will result in reduced susceptibility to insect damage and overall reduction in the use of chemical insecticides. Consult local agricultural authorities for specific IPM strategies developed for your crop(s) and location. Preharvest interval – agricultural use: Spear-T Liquid Concentrate can be applied up to and including the day of harvest
Application: Do not apply this product through any type of irrigation system. Greenhouse Use Directions: Make applications with high pressure, low volume or ultra-low volume (thermal and non-thermal foggers) misters, aerosol generators or hydraulic boom sprayers delivering 40 gallons per acre or less volume. Smaller droplet sizes are most effective. Spear-T Liquid Concentrate is a contact kill material so direct contact with the pest is essential for optimum performance. Mi1 part (e.g. 1 quart (1 liter)) of Spear-T Liquid Concentrate (2.0% active ingredient) with 3 parts (e.g. 3 quarts (3 liters) of water to make 4 quarts (4 liters) of 0.5% active ingredient spray solution. Apply 1 quart (1 liter) of spray solution per 1000 square feet of greenhouse bench space. Spray until wet (glisten), not run-off. Turn off exhaust fans and close vents during application. Begin applications when pests reach threshold levels.
