Problems solved by technology

Emulsions in water and suspensions are environmental-friendly pesticides based on water, but unstable pesticides in water, especially in aqueous media, have antagonistic compositions made into emulsions in water and suspensions that are not conducive to the storage stability of active ingredients; and The water-based emulsions and suspensions developed in my country are generally less effective than emulsifiable concentrates, which increases the use of active ingredients of pesticides, is not conducive to environmental protection, and may increase the resistance of pests

Abstract

The invention discloses a dispersible agent containing spinosads. The dispersible agent of the invention takes plant oil methyl ester as the base material, has strong adhesive force, and can forms a thin film on the surface of a target, thus increasing the precipitation of effective constituent on the target and the capability of the effective constituents for penetrating through the wax coat on the surface of the target, improving the bioavailability of the effective constituents, remarkably reducing the use level of the pesticide, and facilitating to delay the insect resistance; the plant oil methyl ester which is easy to be biodegraded substitutes for an aromatic hydrocarbon solvent, thereby effectively lightening the pesticide photochemical pollution and being beneficial to protectionof ecological environment.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a dispersible liquid containing spinosad. technical background [0002] Spinosyn, also known as spinosad (Spinosad), is a macrolide pollution-free biopesticide extracted from the fermentation broth of Saccharopolyspora spinosa. [0003] Spinosad has rapid contact and stomach poisoning effects on pests, has a strong penetrating effect on leaves, can kill pests under the epidermis, has a long residual effect, and has a certain ovicidal effect on some pests. No systemic effect. It can effectively control pests of Lepidoptera, Diptera and Thysanoptera, and can also control some pests in Coleoptera and Orthoptera that eat leaves in large quantities. It is effective against sucking pests and mites. The control effect is poor. [0004] Its mechanism of action is considered to be the effector of the nicotinic acid acetylcholine receptor, which can continuously activate the target insect acet...
