Problems solved by technology

[0007] In view of the above problems, in order to solve the problem that a single fungicide is prone to drug resistance, the inventors found after repeated experiments that the combination of thiazole zinc and fluthiapiprofen can effectively prevent and treat diseases, and has a significant synergistic effect. As a result, the amount of spraying is reduced, so that the cost is also reduced

Abstract

The invention discloses a composition containing zinc thiazole and oxathiapiprolin, wherein the composition comprises the zinc thiazole and the oxathiapiprolin, wherein the weight ratio of the zinc thiazole to the oxathiapiprolin is 1: (0.01-100). According to the composition disclosed by the invention, when the zinc thiazole and the oxathiapiprolin in the composition are present in a specific weight ratio, the bactericidal activity is greater than the bactericidal activity sum of the zinc thiazole and the oxathiapiprolin, and the synergistic 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 thiazole zinc and fluthiapiprofen, 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, a...
