Abstract

The invention provides a method for preventing and removing plant pythium. The method comprises the step that a sterilizing compound containing chlorothalonil and fenamidone is applied on a plant propagation material or the environment where the plant propagation material is located, wherein the weight ratio of chlorothalonil to fenamidone in the compound is (5:1)-(100:1). The method for preventing and removing plant pythium comprises the step that seeds are enabled to be in contact with the sterilizing compound before seeding and / or after sprouting.

Description

[0001] This application is a divisional application with the application number 201410312833.1, the application date is July 02, 2014, and the invention title is "a method for controlling Pythium in plants". technical field [0002] The invention relates to a method for controlling plant pythium. Background technique [0003] Chlorothalonil, its chemical name is 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile. Its structural formula is: [0004] [0005] 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 aw...
