Problems solved by technology

[0006] In view of the above-mentioned problems, in order to solve the problem that a single bactericide is prone to drug resistance and narrow bactericidal spectrum, the inventors found after repeated experiments that the combination of zinc thiazole and benalaxyl can effectively prevent and treat diseases, and has a significant increase. Efficacy, resulting in lower application rates, resulting in lower costs

Abstract

The invention discloses a composition containing zinc thiazole and benalaxyl-M, and the composition comprises zinc thiazole and benalaxyl-M with a weight ratio being 1:(0.02-50). When the active ingredients of zinc thiazole and benalaxyl-M are existed in a specific weight ratio, the bactericidal activity is greater than the sum of the bactericidal activity of zinc thiazole and benalaxyl-M, and thesynergistic effect is very remarkable.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a composition containing zinc thiazole and benalaxyl-p-ethyl, as well as its preparation and application. Background technique [0002] In the actual production of crops, various diseases caused by various bacteria and fungi are often encountered. In addition to the necessary agricultural measures to prevent and control these diseases, the use of fungicides is essential. However, in most cases, the activity of a fungicide is often unable to effectively control diseases caused by multiple bacteria, fungi, etc. due to the limitation of its bactericidal spectrum, and repeated and large-scale use of a single fungicide will lead to the resistance of bacteria. Drugs are getting worse. Therefore, compounding fungicides is an effective and practical way to solve the above problems in order to expand the bactericidal spectrum, improve the control effect, reduce the dosage,...
