Abstract

The invention provides a kasugamycin-containing pesticide composition which comprises a component A and a component B, wherein the component A is kasugamycin, the component B is metominostrobin, orysastrobin or dimoxystrobin, and the weight ratio between the component A and the component B in the pesticide composition is (1:50)-(50:1). The preparation composition provided by the invention has an obvious synergistic effect, thus improving the controlling effect; and after being compounded for use, the kasugamycin-containing pesticide composition is conductive to overcoming and delaying the generation of pathogenic bacteria drug resistance, thus having great significance for the resistance management of drug, reducing the dosage, lowering the cost and reducing the environmental pollution.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a pesticide composition containing kasugamycin. Background technique [0002] Rice is one of the main grain crops in my country. The national rice planting area accounts for about 30% of the grain crop area, and the output is close to half of the total grain output. Rice blast is one of the important diseases of rice. The disease is widely distributed and occurs in both the northern and southern rice regions of my country. In areas where the disease is prevalent, it can cause a substantial reduction in production, and in severe cases, the production will be reduced by 40% to 50%, and even the grains will not be harvested. Due to long-term single and continuous use of conventional agents such as tricyclazole, Daobenling, and Isidaobenjing for the control of rice blast, the resistance of pathogenic bacteria to them has become more and more serious, and the control ef...
