Bactericidal composition containing boscalid and flusilazole and application thereof

Abstract

The invention discloses a bactericidal composition containing boscalid and flusilazole and application thereof. The bactericidal composition is mainly composed of boscalid and flusilazole in the weight ratio of 1-70:1 ~50. The bactericidal composition can be applied to the prevention and control of diseases of cereals, fruit trees and vegetables, has high synergistic effect, can overcome and delay drug resistant of bacteria, is fast in sterilization speed and long in duration, and reduces the application cost, and the control effect is obviously better than that of a single agent. The bactericidal composition can be used for prevention and treatment of fungal diseases of crops, is especially can be used to control powdery mildew, gray mold, rape sclerotinia and rot, scab, glume blight, leaf spot, rust and other fungus diseases, and the effect is better than that of a single agent.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with boscalid and flusilazole as main active ingredients and its application. Background technique [0002] Boscalid is a new type of nicotinamide fungicide developed by BASF, Germany, chemical name: 2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide, molecular formula: C 18 h 12 Cl 2 N 2 O. The structural formula is as follows: [0003] [0004] The fungicide has a wide bactericidal spectrum and is active against almost all types of fungal diseases. It is very effective in the control of powdery mildew, gray mold, sclerotinia and various rot diseases, and is also effective against other fungal resistant bacteria. , for canola, beans, bulb vegetables, mustard greens, carrots, apples, lettuce, peanuts, potatoes, stone fruits, strawberries, nuts, cabbage, cucumbers, mint, peas, root vegetables, sunflowers, grapes, turf, other fruit t...

AI Technical Summary

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
