Problems solved by technology

[0005] Propiconazole and hexaconazole are two triazole fungicides widely used in China. They mainly control powdery mildew, anthracnose, leaf spot, and rust on fruit trees, vegetables, and field crops. However, they have been used for many years and have become resistant to them. reported, leading to a decrease in the effect
And pyraclostrobin is a new type of fungicide, although the bactericidal effect is good, but the price is more expensive

Abstract

The invention belongs to the field of pesticide fungicides, in particular to a compound fungicide composition containing pyraclostrobin. The invention aims to provide a bactericidal composition which expands the control range, improves the control effect, delays the drug resistance, and reduces the dosage and agricultural cost. The technical solution is: a bactericidal composition, which contains active ingredients A and B, wherein A is pyraclostrobin, and B is one of propiconazole or hexaconazole. The weight ratio of A and B is 10:1˜1:10. The present invention also includes carriers and auxiliaries to be formulated into emulsifiable concentrates, wettable powders, microemulsions, water emulsions, water suspensions or water dispersible granules, etc. The total weight percentage of the active ingredients A and B in the bactericidal composition is 1%-90%. The invention has the beneficial effects of improving the control effect, delaying drug resistance, and reducing the dosage and agricultural cost.

Description

technical field [0001] The invention belongs to the field of pesticide fungicides, in particular to a compound fungicide composition containing pyraclostrobin. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, the chemical name is, methyl(N)-[[[1-(4-chlorophenyl)pyrazol-3yl)-oxygen]-O-methoxy] -N-methoxycarbamate. It is a newly developed methoxyacrylate fungicide in recent years. Its mechanism of action is a mitochondrial respiration inhibitor, which prevents mitochondria from producing and providing the energy required for normal cell metabolism, and eventually leads to cell death. Pyraclostrobin has a broad bactericidal spectrum, and can control most diseases such as Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes. It has a strong inhibitory effect on the germination of spores and the growth of mycelium in leaves. It has protective and therapeutic activities, and has permeability and local systemic activity. It has a long-lasting effe...
