Abstract

The invention discloses a composition containing thiazole zinc and king copper and its preparation and application. The composition comprises thiazole zinc and king copper, wherein the weight ratio of thiazole zinc and king copper is 1:(0.01-100 ). When the active ingredients thiazole zinc and king copper exist in a specific weight ratio in the composition of the present invention, the fungicidal effect is greater than the sum of the fungicidal activities when the thiazole zinc and king copper are used alone, and the synergistic effect is very significant.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a composition containing zinc thiazole and copper king, as well as its preparation and application. Background technique [0002] When crops grow, they often encounter a variety of bacteria, fungi, viruses and nematodes, which pose great risks to the growth, breeding, storage and transportation of crops. In addition to the necessary agricultural measures for controlling these diseases, the use of fungicides containing fungicidally active compounds for controlling these diseases is indispensable. However, in most cases, the activity of a fungicide is often unable to effectively control diseases caused by a variety of bacteria, fungi, etc. due to the limitation of its bactericidal spectrum, and its tolerance and bactericidal activity cannot fully meet the requirements of agricultural production. The repeated and large-scale use of a single fungicide at the same time...
