Abstract

The invention relates to a fungicidal composition containing flubeneteram and cyproconazole, a preparation and applications of the fungicidalcomposition and the preparation. The mass ratio of effective components including the flubeneteram and the cyproconazole is 1-10:10-1, and the total content of the flubeneteram and the cyproconazole in the fungicidal composition / the preparation is 10-60% by mass. The fungicidal composition / the preparation has the obvious synergistic effect on prevention and control of soybean rust. The fungicidal composition and the preparation are suitable for preventionand control of wheat powdery mildew, wheat sharp eyespot, the soybean rust, soybean frogeye leaf spot, soybean gray mold, soybean anthracnose or fruit and vegetable leaf spot.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition containing fluphenamide and cyproconazole. Background technique [0002] Fluphenamide (development code: Y13149) is a new type of succinate dehydrogenase inhibitor (SDHI), which has high-efficiency fungicidal activity against powdery mildew and sheath blight. Fluorophenyl ether amide has systemic conductivity, and has the characteristics of rain resistance, low dosage (5-7 grams / mu), and low cost (<200,000 yuan / ton). Its control effect and cost are significantly better than the similar product Thiofuramide. The structural formula of fluorophenyl ether amide is: [0003] [0004] Cyproconazole (Cyproconazole) is a triazole agricultural fungicide with the molecular formula C 15 h 18 ClN 3 O, whose mechanism of action is to inhibit the demethylation of sterols. Star bacteria are effective. The chemical name of cyproconazole is 2-(4...
