Abstract

The invention relates to a bactericidal composition containing fluorobenzene ether amide and ametoctradin, a preparation thereof and an application of the preparation. The mass ratio of the effectivecomponent fluorobenzene ether amide to the effective component ametoctradin is (1-20):(20-1), wherein the total content of the fluorobenzene ether amide and the ametoctradin in the bactericidal composition is 1-80 mass%. The bactericidal composition disclosed by the invention exhibits an obvious synergistic effect on prevention and treatment of rice sheath blight. The bactericidal composition andpreparation provided by the invention are suitable for preventing and treating powdery mildew, sheath blight, wilt, leaf spot, rust disease, sclerotinia sclerotiorum and rice blast of cereal crops oranthracnose of fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition containing fluphenamide and pyramethazone. Background technique [0002] Fluphenamide (development code: Y13149) is a new type of succinate dehydrogenase inhibitor (SDHI), which has excellent control effect on rice sheath blight, and has high-efficiency fungicidal activity on powdery mildew and potato late 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] Ametoctradin (chemical name: 5-ethyl-6-octyl[1,2,4]triazolo[1,5-a]pyrimidin-7-amine) is a triazole pyrimidine fungicide Agents belong to mitochondrial respiration inhibitors, which can hinder energy transfer, th...
