Abstract

The invention relates to the field of pesticide preparations, and in particular relates to a prochloraz microcapsule suspending agent and a compound preparation thereof. The prochloraz microcapsule suspending agent is prepared from prochloraz, a solvent, an emulsifier, a wet dispersing agent, a capsule wall material, an initiator and water. According to the prochloraz microcapsule suspending agent, the technical problem that prochloraz is not suitable for being made into a suspending agent is solved; meanwhile, the microcapsule suspending-suspending seed coating agent provided by the invention can be used for effectively preventing and treating pests and diseases such as rice bakanae disease, rice black-streaked dwarf disease, thrips and rice fulgorid, and has an extremely good slow release effect.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to prochloraz microcapsule suspension and its compound preparation. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. Rice is the main food crop in my country. In addition to food, it can also be used as industrial raw materials for wine making and sugar refining. Rice husk and rice straw can be used as feed. There are many kinds of diseases and insect pests of rice, common diseases and insect pests include rice bakanae disease, rice black-streaked dwarf disease, thrips, planthopper and so on. [0003] Rice bakanae disease, also known as excessive growth disease, is a seed-borne disease that occurs in various rice regions in China. The main manifestations are: diseased grains often do not germinate or cannot be unearthed after sowing; diseased seedlings are thinner and taller ...
