Abstract

The invention relates to a bactericidal composition with synergy. The bactericidal composition comprises the following effective active ingredients of pyrimorph and cyazofamid, wherein the weight ratio of the pyrimorph to the cyazofamid is 1-80:60:1. By adding aids and excipients into the effective active ingredients to prepare wettable powder, water dispersible granules and suspending agents, the bactericidal composition has the advantage of high bioactivity on oomycetes fungi, such as phytophthora, downy mildews, pseudoperonospora, pythium and plasmodiophora brassicae in plasmodiophoramycetes.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a bactericidal composition containing pyrimorph and cyafamid. technical background [0002] Oomycete is a kind of serious plant pathogen in agricultural production at present. It has the characteristics of short generation, large spore production, short incubation period, many times of infection, strong damage to host plants, and fast epidemic speed. . Can cause a variety of plant diseases, such as downy mildew, blight and so on. Bring extremely serious economic loss to agriculture. [0003] Pyrimorph, molecular formula: C 22 h 25 N 2 C 1 o 2 , chemical name: (E)-3-(2-chloropyridin-4-yl)-3-(4-tert-butylphenyl)-acryloylmorpholine. [0004] The structural formula is: [0005] Pyramorph is one of the few new pesticides with independent intellectual property rights in my country. Its mechanism of action is to change the permeability of the cell wall, leading to the leakag...
