Abstract

The invention belongs to the technical field of pesticide and particularly relates to a composition of a bactericide containing bixafen and dimoxystrobin. The effective components of the bactericide composition are bixafen and dimoxystrobin, and the weight ratio of the bixafen to the dimoxystrobin is (30:1):(1:30). The composition adopts the bactericide bixafen and the dimoxystrobin which are different in action mechanisms to be mixed for use, has an obvious synergistic effect on wheat powdery mildew, wheat rust and wheat scab, and effectively controls drug resistance generated by pathogenic microorganisms. Field tests show that when the ratio of the bixafen to the dimoxystrobin is 10:1, after the composition has been used for 7 days, the control effect on wheat rust is up to 93.36%, the control effect on wheat powdery mildew is up to 94.04%, and the control effect on wheat scab is up to 91.57%, and all the control effects are obviously higher than those of a single dosage of bixafen and a single dosage of dimoxystrobin.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicide composition containing bixafen and kresastrobin and an application thereof. Background technique

[0002] Bixafen (Bixafen), its chemical formula is C18H12Cl2F3N3O, its chemical name is N-(3โ€ฒ,4โ€ฒ-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1 -Methylpyrazole-4-carboxamide. Bixafen is a pyrazole fungicide, which is a new type of systemic fungicide with broad-spectrum, protective and therapeutic activities. Bixafen interferes with succinate dehydrogenase on complex II in the mitochondrial respiratory electron transport chain of pathogenic bacteria, inhibits mitochondrial function, prevents it from producing energy, inhibits the growth of pathogenic bacteria, and eventually leads to its death. Bixafen is a systemic fungicide with a broad spectrum of fungicides and is specially used for foliar sprays. Tests have proved that bixafen has excellent con...
