The mechanism of action of spinosad is believed to be the nicotinic acid acetylcholine receptor, which can continuously activate the target insect acetylcholine nicotinic receptor, but its binding site is different from nicotine and imidacloprid. Spinosad can also affect GABA receptors, but the mechanism of action is unclear. It can paralyze and paralyze pests quickly, and finally lead to death. Its insecticide speed is comparable to that of chemical pesticides. It is highly safe and has no cross-resistance with currently commonly used insecticides. It is a low-toxic, high-efficiency, low-residue biological insecticide. It has both high-efficiency insecticide performance and safety for beneficial insects and mammals. It is most suitable for pollution-free vegetable and fruit production applications. It is a low-toxic, high-efficiency, broad-spectrum insecticide.
It has rapid contact and stomach poisoning effects on pests, strong penetration into leaves, can kill pests under the epidermis, has a long residual effect, and has a certain egg-killing effect on some pests. No systemic effect. It can effectively control Lepidoptera, Diptera and Thysanoptera pests, and can also effectively control some species of Coleoptera and Orthoptera that feed on leaves in large quantities. It has poor control effect on piercing-sucking pests and mites. It is relatively safe for predatory natural enemy insects. Due to its unique insecticidal mechanism, no reports of cross-resistance with other insecticides have been found. It is safe for plants and has no pesticide damage. It is suitable for use on vegetables, fruit trees, gardening, and crops. The insecticidal effect is less affected by rain.
Spinosad is mainly used to control pests by spraying, and when luring and killing the orange fruit fly, it is sprayed with bait.
(1) Spraying: When using on cruciferous vegetables, solanaceous vegetables, melon vegetables and cotton, generally use an ointment containing 2-2.5 grams of active ingredients to spray 30-45 liters of water per 667 square meters; when spraying on fruit trees, generally use 480 grams/liter suspension 12000-15000 times liquid, or 25 grams/liter suspension 800-1000 times liquid. The spray should be even and thorough, and the best effect is achieved when the pest occurs in the early stage. When controlling thrips, focus on spraying young and tender tissues such as tender shoots, flowers, and young fruits.
(2) Spot spraying and baiting: When controlling citrus fruit flies, spot spraying and baiting are often used to lure and kill citrus fruit flies. Generally, 10-100 ml of 0.02% bait is sprayed per 667 square meters.
