Abstract

The invention discloses a benzothiostrobin and penthiopyrad containing fungicide composition. The benzothiostrobin and penthiopyrad containing fungicide composition contains benzothiostrobin, penthiopyrad and a commonly used auxiliary agent, wherein the weight ratio of the benzothiostrobin to the penthiopyrad, which are effective components in the composition, ranges from 40:1 to 1:40. After the benzothiostrobin and the penthiopyrad are compounded according to a certain ratio, the pesticide composition provided by the invention has an obvious synergistic effect of controlling plant diseases, especially cucumber downy mildew and citrus anthracnose; the pesticide composition provided by the invention is environment-friendly, low in toxicity and safe to the environment.

Description

Technical field [0001] The present invention relates to a fungicide composition, which uses Benthiostrobin and Penthiozamide as the main active ingredients. The fungicide composition of the present invention shows a synergistic effect on the prevention and control of various plant diseases, especially It is cucumber downy mildew and citrus anthracnose. Background technique [0002] Benzothiostrobin (benzothiostrobin), the chemical name is (E)-2-[2-(5-methoxybenzothiazole-2-thiomethyl)phenyl]-3-methoxybenzoic acid methyl ester , Is a new type of Qo1 fungicide, its mechanism of action is a class of compounds that prevent the electron transfer between pathogenic bacteria cytochrome b and c1, interfere with their respiration and ATP synthesis. It has the advantages of wide bactericidal spectrum, high bactericidal activity, low application rate, long lasting period, etc. It has both therapeutic and protective effects, especially for cucumber downy mildew and cucumber powdery mildew. ...
