Abstract

The invention discloses a spinosad microemulsion and a preparation method thereof. The spinosad microemulsion comprises components of, by weight: 1-20% of spinosad, 5-40% of solvent and cosolvent, 6-20% of emulsifying agent, 1-5% of penetrating agent, 1-5% of synergist and the balance of deionized water. The preparation method is as below: dissolving the spinosad into solvent and cosolvent completely; adding a certain proportion of emulsifying agent, penetrating agent and synergist into a preparation vessel to prepare an oil phase; slowly adding deionized water with stirring at 1000-6000 R / min to supplement to 100%; and examining quality, so as to obtain a transparent spinosad microemulsion. The present invention has advantages of high efficiency, low toxicity, friendliness to the environment, safety to human and animal, and easiness for production and use.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to a spinosad microemulsion and a preparation method thereof. Background technique [0002] Spinosad is a kind of macrolide pollution-free and high-efficiency biopesticide extracted from the fermentation broth of Saccharopolyspora spinosa. It has rapid contact and stomach poisoning effects on pests, and has no systemic effect. It has a strong penetrating effect on the leaves, can kill the pests under the epidermis, has a long residual effect period, and has a certain ovicidal effect on some pests. It can effectively control Lepidoptera, Diptera and Thysanoptera pests, and can also control certain pest species in Coleoptera and Orthoptera that eat a lot of leaves. It is relatively safe for predatory natural enemy insects. Due to the unique mechanism of insecticidal action, no reports of cross-resistance with other insecticides have been found so far. ...
