Problems solved by technology

The use of benzene solvents increases the residue of toxic substances in crops, reduces the quality of agricultural products, causes serious soil, water and air pollution, and is harmful to human health
Microemulsion is a water-based preparation that has been successfully developed in recent years. It has certain advantages in low-content preparations. In the preparation of medium-high content preparations, organic benzene solvents and a large number of additives are still needed, resulting in serious photochemical pollution and waste of resources.
Emulsions in water and suspensions are two other pesticide formulations based on water, but pesticides that are unstable in water, especially those that are antagonistic in water media, are made into emulsions in water and suspensions, which are not conducive to the storage stability of active ingredients. Moreover, water-based emulsions and suspensions are generally less effective than emulsifiable concentrates, which increases the use of active ingredients of pesticides, is not conducive to environmental protection, and may accelerate pest resistance

Abstract

The invention discloses a dispersible agent containing abamectin. 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 constituents on the surface of 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 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 protection of ecological environment.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a dispersible liquid containing abamectin. technical background [0002] Abamectin is a macrolide disaccharide compound, which is a biopesticide isolated from soil microorganisms. It has a strong penetrating effect on plant leaves, can kill pests under the epidermis, and has a long-lasting effect. Its mechanism of action is different from that of chemical pesticides in that it interferes with neurophysiological activity and stimulates the release of GABA. Therefore, abamectin is widely used in compounding with chemical insecticides and acaricides to expand insecticidal spectrum, improve drug efficacy and reduce costs. For example: patent applications such as publication numbers CN101300979, CN101406185, CN101380008, CN101019540, CN101156580, CN1663381 disclose the composition of abamectin and spirofen, lufenuron, chlorfenapyr, nitenpyram, spinosad, etc. , in these patent applications...
