Abstract

The invention provides a fungicide composition and application thereof. Active components of the fungicide composition include meptyldinocap and one or at least two of azoxystrobin, trifloxystrobin, fluoxastrobin, dimoxystrobin, picoxystrobin, metominostrobin, orysastrobin, enestroburin, pyraoxystrobin and SYP-1620, wherein the weight ratio of the two components is (1 to 50)-(50 to 1). The invention further provides the application of the fungicide composition in the prevention and control of plant diseases caused by fungi. The fungicide composition has the beneficial effects that compared with the sterilizing effect of a single component, the sterilizing effect is remarkably improved, an excellent synergistic effect is achieved, the consumption of a medicament is reduced, the pesticide cost of farmers is lowered, and meanwhile, the environmental influence is alleviated; meanwhile, the bactericidal spectrum is expanded, and the generation and development of resistance of the single component can be effectively delayed.

Description

technical field [0001] The present invention relates to the field of agricultural fungicides, in particular, relates to a method selected from azoxystrobin, trifloxystrobin, fluoxastrobin, kresoxstrobin, picoxystrobin, fenoxystrobin, A fungicide composition in which one or more of oryzastrobin, pyroxastrobin, pyraclostrobin, and pyrastrostrobin are active ingredients and application thereof. Background technique [0002] Metrastrobin is a mitochondrial oxidative phosphorylation uncoupler, a contact fungicide with a certain osmotic activity, which provides protection, treatment and eradication by inhibiting spore germination and fungal respiration and disrupting the metabolism of fungal cells. The chemical name of Memethystrobin is 2-(1-methylheptyl)-4,6-dinitrophenyl(2E)-butenoate (2-(1-methylheptyl)-4,6-dinitrophenyl (2E)-2-butenoate), its molecular formula is C18H24N2O6, its molecular weight is 364.4, its structural formula is: [0003] [0004] Azoxystrobin belongs t...
