Abstract

The invention discloses a bactericidal composition containing penconazole and propamocarb and an application thereof. The bactericidal composition has two main active ingredients, namely penconazole and propamocarb. Weight ratio of penconazole to propamocarb is 1-70:1-50. The bactericidal composition can be applied in preparation of bactericida medicines for controlling fungal diseases on cereals, fruit trees and vegetables, has obvious synergetic effects on fungal diseases such as powdery mildew, venturia inaequalis, downy mildew, late blight, rust disease, black shank and the like, overcomes and delays drug resistance of germs, and has fast bactericidal speed and long duration. Application costs are reduced. Control efficiency of the bactericidal composition is obviously superior to that of a single dosage.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with penconazole and propamocarb as main active ingredients and its application. Background technique [0002] Penconazole (Penconazole), molecular formula: C 13 h 15 Cl 2 N 3 , chemical name: 1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4-triazole. Structural formula: [0003] [0004] Penconazole is a triazole fungicide developed by Syngenta. Its main mechanism of action is a sterol demethylation inhibitor, which destroys and prevents the biosynthesis of ergosterol, an important component of the cell membrane of pathogens, resulting in the inability of the cell membrane to form. Germs die, because of their good systemic properties, they can be quickly absorbed by plants and conducted internally. They have good protective and therapeutic activities, and can effectively prevent and control diseases caused by basidiomycetes and half-kn...
