Abstract

The invention provides a method for controlling plant pythium. According to the method, a bactericidal composition containing chlorothalonil and fenamidone is applied in a plant propagation material or an environment thereof, wherein the weight ratio of chlorothalonil to fenamidone in the composition is5:1 to 100:1. The plant pythium controlling method provided by the invention comprises a step of bringing seeds in contact with the bactericidal composition before sowing and / or after germination.

Description

technical field [0001] The invention relates to a method for controlling plant pythium. Background technique [0002] Chlorothalonil, its chemical name is 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile. Its structural formula is: [0003] [0004] Chlorothalonil is a broad-spectrum, protective fungicide that replaces benzene. The mechanism of action is that it can interact with glyceraldehyde triphosphate dehydrogenase in fungal cells, combine with the cysteine-containing protein in the enzyme, thereby destroying the enzyme activity, destroying the metabolism of fungal cells and losing their vitality. Chlorothalonil has no systemic conduction effect, but after being sprayed on the plant body, it can have good adhesion on the body surface and is not easily washed away by rain, so the efficacy period is longer. Chlorothalonil is mainly used for the control of rust, anthracnose, powdery mildew and downy mildew on fruit trees and vegetables. [0005] Fenamidone, chemical n...
