Bactericidal composition containing fluopyram and iprodione

Abstract

The invention relates to a bactericidal composition in the field of pesticide compounding. The active ingredients of the bactericidal composition are fluopyram and iprodione in a mass ratio of 1-40:40-1, preferably 1-20:20-1, further preferably 1-15:15-1; the total active ingredients account for 1 to 90 percent, 20 to 60 percent preferably in the bactericidal composition, and the rest is acceptable auxiliary components allowed to be used in the pesticide; and the bactericidal composition is prepared into emulsifiable concentrate, wettable powder, water dispersible granules and a suspending agent. The bactericidal composition compounded by the fluopyram and iprodione serving as the active ingredients according to a certain ratio has obvious synergy for controlling diseases such as powdery mildew and downy mildew of vegetables, fruit trees and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a fungicidal composition containing fluopyram and iprodione. Background technique [0002] Fluopyram, English common name fluopyram, chemical name is N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl]ethyl-α,α,α-trifluoro-O -Toluamide}, a novel benzamide fungicide, inhibits mitochondrial respiration by blocking the electron transfer of succinate dehydrogenase in the respiratory chain. It is mainly used to control diseases caused by cyst fungi on broad-leaved crops. It has a good control effect on downy mildew and powdery mildew on vegetables such as cucumbers and zucchini, downy mildew on fruit trees and other diseases caused by pathogens. Its chemical structural formula is: [0003] [0004] Iprodione, the common name in English is iprodione, and the molecular formula is C 13 h 13 Cl 2 N 3 o 3 , chemical name: 3-(3,5-dichlorophenyl)-N-isopropyl-2,4-dioxoimidazoline-1-carboxamide,...
