Sterilization composition containing penconazole and benthiavalicarb-isopropyl, and applications thereof

Abstract

The present invention discloses a sterilization composition containing penconazole and benthiavalicarb-isopropyl, and applications thereof, wherein the sterilization composition adopts penconazole and benthiavalicarb-isopropyl as main effective components, and a weight ratio of the penconazole to the benthiavalicarb-isopropyl is 1-70:1-50. The sterilization composition of the present invention can be used for preparation of sterilization drugs for prevention and control of fungi plant diseases of cereal, fruit trees and vegetables, provides significant synergy effects on powdery mildew, scab, downy mildew, late blight, rust disease and other fungi plant diseases, has characteristics of pathogenic bacterial drug resistance overcoming and delaying, rapid sterilization, long last period and application cost reducing, and provides the more excellent prevention and control effect compared with the use of the single agent.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with penconazole and benthiazil 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-kno...

Problems solved by technology

[0008] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge
