Abstract

The invention discloses a composite bactericide. The composite bactericide comprises the following components in percentage by weight: 5 to 90 percent of procymidone and 10 to 95 percent of component B, wherein the component B is difenoconazole, tebuconazole, triazolone, propiconazol or myclobutanil. The invention also discloses an emulsion-type bactericide which is prepared from the composite bactericide. Each L of the emulsion-type bactericide comprises 50 to 900 g of the composite bactericide. The invention also discloses a powder/grain-type bactericide which is prepared from the composite bactericide. The powder/grain-type bactericide comprises 10 to 90 weight percent of the composite bactericide. The composite bactericide can be used for preventing fungal diseases of vegetables, fruit trees or rape.

Description

technical field [0001] The invention relates to a fungicide, in particular to a compound fungicide for preventing and treating diseases of vegetables, fruit trees and rapeseed. Background technique [0002] Procymidone [procymidone, N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarbonylimide] is effective against Botrytis sp. It has a good control effect on plant diseases caused by various pathogenic fungi such as Alternaria and Alternaria. Studies have shown that the agent inhibits fungal growth by activating the fungal two-component histidine kinase signaling pathway. Phosphorylation levels of OS-2 in fungi such as Botrytis cinerea and Colletotrichumlagenarium increased rapidly after chemical treatment, and the TCHK signaling pathway of the fungi was continuously activated, resulting in a large amount of glycerol accumulation in the fungi. eventually lead to cell death. [0003] Procymidone is a broad-spectrum contact-killing modern protective fungicide launched...
