Abstract

The invention relates to a bactericide compound and application thereof. The bactericide compound is compounded, by weight, effective components of 1-20% of dimethomorph, 8% of cymoxtheil and 64% of mancozeb. Dimethomorph has an upward uptake and conduction effect, frosted urea manganese zinc has a local permeation effect and a protecting effect, dimethomorph and frosted urea manganese zinc have totally different action mechanisms and have no cross resistance, when dimethomorph and frosted urea manganese zinc are compounded together, the dose can be reduced, and the service life of agents canbe prolonged.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicide composition compounded from dimethomorph, cymoxanil and mancozeb. technical background [0002] Downy mildew and late blight are one of the most serious diseases that harm vegetables and fruit trees in my country, and are also a worldwide disease. Especially when the diseases are prevalent, they often bring huge losses to vegetable and fruit farmers. Chemical control is the main means to prevent such diseases. Cymoxanil·mancozeb is a mixture of cymoxanil and mancozeb, containing 8% cymoxanil and 64% mancozeb. The drug is a broad-spectrum fungicide, which has the ability to inhibit spore production, spore infection and control the spread of pathogens. It is a protective fungicide for various leaf diseases. Disease control is better. However, due to the long-term and extensive use of cymoxanil·manganese zinc wettable powder in China, the resistance of diseases t...
