Abstract

The invention discloses a compound pesticide containing fosthiazate, tebuconazole and prochloraz, a preparation method and an application thereof, wherein the compound pesticide includes 1-15 parts of fosthiazate, 0.05 to 10 parts of tebuconazole and 0.5 to 2 parts of prochloraz. The compound pesticide can effectively overcome the disadvantage that the traditional insecticide cartap for preventing and treating aphelenchoides besseyi is narrow, degradable and unsteady, a treating agent for avoiding rice seed to spread disease can be developed into an emulsifiable concentrate, an emulsion in water, a suspension concentrate and a high-efficiency environmental-protection agent. The compound pesticide is compounded with tebuconazole and prochloraz to enhance fosthiazate permeability and obviously reduce fosthiazate dosage in per mu.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a compound pesticide containing thiazophosphine, tebuconazole and prochloraz, and a preparation method and application thereof. Background technique [0002] Rice bakanae disease and dry sharp nematode are two common bell-borne diseases of rice in my country. Among them, rice bakanae disease is soaked with prochloraz all the year round, which leads to the obvious resistance of the pathogenic bacteria to prochloraz and the control effect decreases. [0003] Rice apical nematode disease occurs in all countries in the world. Although the leaf symptoms of the disease are mild, the number of grains per panicle decreases and the thousand-grain weight decreases due to the pricking and sucking damage to the ear primordium by the apical nematode during rice spikelet differentiation. Often cause serious damage to rice production. [0004] Cartap has been used for more than 30 years as a medicam...
