New Product Spinosad

Hello, come to consult our products !

Spinosad,  is a macrolide non-polluted high-efficiency biological insecticide extracted from the fermentation broth of Saccharopolyspora spinosa. The parent strain that produces spinosyn, Saccharopolyspora spinosa Metrz & Yao (Saccharopolyspora spinosa Metrz & Yao) was originally isolated from an abandoned winery in the Caribbean. The practical product is a mixture of spinosyn A and spinosyn D, so it is called spinosad.

Spinosad has a novel mode of action. Its mechanism of action is considered to be the actor of the nicotinic acetylcholine receptor, which can continuously activate the target insect acetylcholine nicotinic receptor, but its binding site is different from nicotine and imidacloprid. Spinosyn can also affect GABA receptors, but the mechanism of action is unclear. It can quickly paralyze and paralyze the pests, and eventually lead to death. Its insecticidal speed is comparable to chemical pesticides. High safety, and no cross-resistance with the current commonly used insecticides. It is a low-toxicity, high-efficiency, low-residue bio-insecticide. It has both high-efficiency insecticidal performance and safety characteristics for beneficial insects and mammals. It is suitable for the production and application of pollution-free vegetables and fruits. It is a low-toxicity, high-efficiency, broad-spectrum insecticide.

It has quick contact and stomach poisoning effects on pests, and has a strong penetration effect on leaves, which can kill pests under the epidermis. The residual effect is longer, and it has a certain egg-killing effect on some pests. No systemic effect. It can effectively control Lepidoptera, Diptera and Thysanoptera pests, and it can also control certain leaf-feeding pests in Coleoptera and Orthoptera effectively. It can also control piercing-sucking pests and mites. The effect is poor. It is relatively safe to predatory natural enemy insects. Due to the unique insecticidal mechanism, there are no reports of cross-resistance with other insecticides. It is safe and harmless to plants. Suitable for use on vegetables, fruit trees, gardening and agricultural crops. The insecticidal effect is less affected by rain.

Spinosad is mainly used to control pests by spraying. When trapping Bactrocera dorsalis, spot spraying is used as bait.

(1) Spray on cruciferous vegetables, solanaceous vegetables, melon vegetables and cotton: when used, generally use a medicine containing 2 to 2.5 grams of active ingredients per 667 square meters to spray 30 to 45 liters of water; in fruit trees When spraying on top, generally use 12000~15000 times liquid of 480 g/L suspending agent, or 800-1 000 times liquid of 25 g/L suspending agent, and spray zero spray should be uniform and thoughtful, and the best effect is in the early stage of pest occurrence. When controlling thrips, spray young tissues such as tender shoots, flowers, and young fruits.

(2) Point spraying bait When controlling citrus fruit flies, point spraying bait medicine is often used to trap and kill fruit flies. Generally, 10-100ml of 0.02% bait is sprayed per 667 square meters.
