Pyrazole kresoxim and thiophanate-methyl composite fungicide

Abstract

The invention belongs to the technical field of pesticides and relates to pyrazole kresoxim and thiophanate-methyl composite fungicide for controlling diseases on fruit trees, vegetables and grains. The fungicide has a technical scheme of adopting a suspension agent which comprises the following components in percentage by weight: 1.0 to 10 percent of pyrazole kresoxim, 10 to 40 percent of thiophanate-methyl, 0.5 to 6 percent of agricultural organosilicon, 2.0 to 10 percent of wetting agent, 2.0 to 10 percent of dispersing agent, 0.1 to 10 percent of stabilizing agent, 0.1 to 3 percent of thickening agent, 1.0 to 8 percent of antifreeze agent, 0.1 to 3 percent of defoaming agent and the balance of water. The invention has the advantages of avoiding drug resistance in the long-term use of single preparation, being capable of remarkably prolonging the using time of the drug, reducing the using amount and the using cost, improving the curative effect and having good synergetic effect, long acting period, good control effects on a plurality of diseases, low toxicity, no pollution and environmental security.

Description

technical field The invention belongs to the technical field of pesticides, and relates to a pyraclostrobin and thiophanate-methyl compound fungicide used for preventing and controlling diseases on fruit trees, vegetables and grains. Background technique Pyraclostrobin, chemical name: N-{2-[[1-(4-chlorophenyl)pyrazole-3-yl]oxymethyl]phenyl}-N-methoxycarbamic acid methyl ester. Pyraclostrobin is a broad-spectrum fungicide, effective against strawberry powdery mildew, cucumber downy mildew; pear scab, leaf spot, grape downy mildew, anthracnose, powdery mildew, early blight and late blight of tomato and potato , powdery mildew, leaf blight; wheat powdery mildew, sheath blight, rust, etc. have good control effect. It is widely used in the disease control of fruit trees, vegetables, tea trees, tobacco and ornamental plants, lawns and other field crops. Thiophantate-Methyl, chemical name: 1,2-di(3-methoxycarbonyl-2-thioureido)benzene[1,2-di-(3-methoxycarbonyl-2-thioureido) Be...

AI Technical Summary

Problems solved by technology

The above-mentioned pyraclostrobin and thiophanate-methyl components have been used as single doses for a long time, and the crops are prone to drug resistance, which shortens the duration of the drug, increases the frequency of application, and increases the cost of disease control. restricted
