Abstract

The invention relates to a bactericidal composition, and relates to a method for controlling plant diseases. The bactericidal composition comprises the active components of chlorothalonil and iprovalicarb with a weight ratio of 1:100-100:1. According to the invention, chlorothalonil and iprovalicarb are subjected to binary complexing, such that the obtained bactericidal composition has a synergistic effect in the controlling effect. Also, the bactericidal spectrum is expanded, and the composition has multiple effects. According to the invention, with the binary complexing of chlorothalonil and iprovalicarb, a disease prevention effect can be improved, and germ drug resistance is prevented. The composition can be used for controlling downy mildew, blight and damping-off diseases of melons, fruits, vegetables and grapes.

Description

technical field [0001] The invention relates to a fungicidal composition and also relates to a method for preventing and controlling plant diseases. 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...
