Abstract

The invention discloses a functional pymetrozine insecticide and a preparation method thereof. Functional pymetrozine forms a functional wettable powder under combined actions of a wetting agent, a dispersing agent and a functional addition agent and the like, or the functional pymetrozine, the dispersing agent, a disintegrating agent and the functional addition agent and the like are ground through a jet mill and then pelletized to form functional water-dispersible granules, and the functional pymetrozine can also be ground jointly with water to form a functional suspending agent under the actions of an emulsifying agent, the dispersing agent and the functional addition agent and the like. The efficient functional preparation is good in control effect and safe to use and is an excellent preparation for controlling pests on various crops such as vegetables, rice, cotton, fruit trees and the like.

Description

Technical field [0001] The invention relates to a pesticide, in particular to several highly efficient functional formulations of pyridine pesticide insecticide-pymetrozine. Background technique [0002] For a long time, the field of pesticide formulations in my country has had low product penetration, and a large amount of ineffective pesticide active ingredients are lost and volatilized, causing great waste in the process of pesticide use, which not only greatly reduces the efficacy of the pesticide, and reduces the income of agricultural products, but also Pollution to the atmosphere, soil, water quality and the entire ecological environment. [0003] In the current situation of increasing population, decreasing land, increasing food demand, and increasingly severe environmental requirements, people need to develop more safe and efficient pesticide products. [0004] Pymetrozine is a new broad-spectrum insecticide. The currently used preparations also have low efficacy and poor pe...
