Abstract

The invention relates to a pesticide composition containing pyraclostrobin and metalaxyl. The pesticide composition comprises common aids, pyraclostrobin and metalaxyl, wherein the mass part ratio of the pyraclostrobin to the metalaxyl is (6:1)-(1:15), preferably (4:1)-(3:25). The compound pyraclostrobin and metalaxyl have an obvious synergistic effect, so that the pesticide resistance of pathogenic bacteria of plants is delayed, the effect lasting time is long, the consumption and the using frequency of pesticide can be reduced, the cost is reduced, the use is convenient, the time and the labor are saved, and the environmental pollution is reduced. The pesticide composition is suitable for preventing and treating diseases of crops.

Description

technical field [0001] The pesticide composition of the present invention uses pyraclostrobin and metalaxyl as active ingredients, and is mainly suitable for preventing and controlling crop diseases and downy mildew. Background technique [0002] Pyraclostrobin, English common name: pyraclostrobin, chemical formula: C 19 h 18 ClN 3 o 4 , chemical name: methyl N-[2-[[1-(4-chlorophenyl)pyrazol-3-yl]oxymethyl]phenyl]-N-methoxycarbamate. It is a methoxyacrylate fungicide, which has a wide bactericidal spectrum, high activity, preventive and therapeutic effects, and has good compatibility with the environment. A variety of plant diseases caused by it have good control effects, especially for powdery mildew, anthracnose and blight. With high activity and low dosage, it is widely used to prevent and control crop diseases. However, due to the single action site of this type of fungicide, the bacteria will develop resistance to the drug quickly. [0003] Metalaxyl, English com...
