Bactericidal composite with famoxadone and application thereof

Abstract

The invention belongs to the technical field of agricultural fungicide, in particular relates to a bactericidal composite with famoxadone and an application thereof. The composite of the invention is prepared by combining famoxadone with another fungicide component B, wherein the fungicide B is at least one of metalaxyl, metalaxyl-M, propamocarb, cyazofamid and oxadixyl. The composite is used to prevent the plant disease caused by pathogenic fungi, in particular to prevent the tobacco black shank and downy mildew, blight and peronophythora of melons, fruits, vegetables and other crops, and has obvious synergistic effect and good effect on preventing and delaying the drug resistance of pathogenic fungi.

Description

technical field [0001] The invention belongs to the technical field of agricultural fungicides, and in particular relates to a fungicidal composition containing oxaconazole and its application. Background technique [0002] Famoxadone (Famoxadone) chemical name 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazoline-2,4-dione, belongs to oxazoles Fungicide is an energy inhibitor, that is, mitochondrial electron transfer inhibitor, which has inhibitory effect on cytochrome C oxidoreductase in complex I II, and has protection, treatment, eradication, penetration and systemic activities. Oxafluconone is a new type of high-efficiency and broad-spectrum fungicide, which has good activity against diseases caused by pathogenic fungi such as Ascomycetes, Basidiomycetes, and Oomycetes. However, due to the fact that the electron transfer site of oxaflucondone inhibits the mitochondria is very single, the bacteria are prone to adaptive variation to the drug, which reduces the control eff...
