Abstract

The invention belongs to the field of pesticides, and particularly provides an orysastrobin and metconazole-containing sterilization composition. An effective component of the orysastrobin and metconazole-containing sterilization composition is obtained by compounding orysastrobin and metconazole; the mass ratio of the orysastrobin to the metconazole is (1 to 40): (40 to 1). The orysastrobin and metconazole-containing sterilization composition has an obvious synergistic effect and can delay generation of key drug resistance, and the production cost and the use cost are reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, and specifically provides a fungicidal composition containing orysastrobin and metconazole. Background technique [0002] Orysastrobin (orysastrobin) is a methoxyacrylate fungicide, which is currently mainly used in rice to control rice blast and sheath blight. The drug effect is achieved by inhibiting the action of cytochrome bc1 in the electron transfer system of one of the respiratory pathways in the microsomes of pathogenic bacteria cells. It can inhibit the germination of spores and the formation of appendages on the life cycle of pathogenic bacteria. It is effective against the mycelium of the blast fungus that invades the rice body, and strongly hinders the growth of the mycelium; and for the rice sheath blight, it controls the increase of the fungus stem by hindering the growth of the mycelium that invades the rice body. [0003] Metconazole (Metconazole) is a high-efficiency, broad-spectrum, ...
