Abstract

The invention provides a cyprodinil-containing germicide composition. The composition comprises an effective active ingredient A and an effective active ingredient B, wherein the effective active ingredient A is cyprodinil; and the effective active ingredient B is one of carbendazol and thiophanate methyl. The germicide composition comprises the following components by weight: 5 to 79 percent of cyprodinil serving as the effective active ingredient A, 10 to 79 percent of thiophanate methyl or carbendazol serving as the effective active ingredient B and the balance of an auxiliary agent and an excipient. The compound composition of the cyprodinil and the thiophanate methyl is prepared into wettable powder, water dispersible granules and a suspension agent and has obvious synergistic effect of preventing and treating alternaria leaf spot and fruit rot of apple, sigatoka, grape powdery mildew, vegetable powdery mildew, pear scab, rice blast and anthracnose.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition compounded with cyprodinil and carbendazim or thiophanate-methyl, which is used for preventing and treating banana leaf spot, apple spotted leaf spot, grape powdery mildew, vegetable Powdery mildew, anthracnose. technical background [0002] Fungi are the most important plant pathogenic bacteria, and more than 70% of plant diseases are caused by fungi. Because of the complex pathogenic factors, it is very difficult to control them. In recent years, with the adjustment of the rural planting structure, the planting area of ​​fruit trees has been increasing, and the occurrence of many fungal diseases on fruit trees has also increased, causing huge economic losses. [0003] Apple is the fruit tree variety with the largest planting area in my country. However, due to the serious occurrence of fungal diseases such as apple spot leaf defoliatio...
