Abstract

The invention discloses a compound pesticide synergist. According to the invention, two or more of surfactants, penetrants and speaders are compounded according to a certain ratio to form the compound pesticide synergist; the compound pesticide synergist has obvious synergistic effects on most pesticide preparations, and can significantly reduce pesticide consumption under the same control effect. The compound pesticide synergist provided by the invention completely accords with national indicators, and is beneficial to improving the service efficiencies of the effective ingredients of pesticide preparations so as to allow the pesticide preparations to be more environmental-friendly.

Description

technical field [0001] The invention relates to a compound pesticide synergist, in particular to the application in pesticide emulsifiable concentrate, microemulsion and water emulsion preparations. Background technique [0002] In pesticide formulations, surfactants, penetrating agents, and spreading agents play an important role. They are not only emulsifiers, but also regulators for active ingredients and spraying agents. They can make two incompatible liquids dissolve, and can also Reduce the surface tension of the liquid and enhance the penetration and spreading performance of the liquid on the action surface. [0003] Commonly used surfactants have low molecular weight, and usually cannot completely cover the surface of particles (or droplets), and are also easy to fall off and transfer from the surface. The wetting, spreading, and penetrating properties of pesticide droplets can be significantly improved by scientifically combining surfactants, penetrating agents, an...
