Abstract

The invention discloses a compound synergistic bactericidal composition, the effective ingredients of which are zoxamide (A) and (B) which is one active ingredients of cyazofamid, cymoxanil, propamocarb and thiram, wherein the mass ratio of the effective ingredients A to B is 50:1-1:50. The effective ingredients A and B have obvious synergized action after being compounded in a certain proportionrange, and are mainly used for preventing and treating oomycete diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compounded and synergistic bactericidal composition containing benzamid. Background technique [0002] Oomycete diseases such as downy mildew and blight are very important diseases on fruit trees and vegetables, which seriously affect the yield and quality of crops and cause huge losses to agricultural production. In the 19th century, tens of thousands of people died of starvation due to the potato blight epidemic in Ireland. According to literature reports, the cost of pesticides used to prevent downy mildew and blight of vegetables and melons in my country in 1997 was 796 million yuan. In recent years, it has also been showing a rising trend. With the advent of metalaxyl, oomycete diseases have been effectively controlled, but the long-term single use of metalaxyl quickly led to the resistance of the bacteria; subsequently, propamocarb, cymoxan and other agents used in agricultu...
