Fungicidal composition containing boscalid and kresoxim-methyl and application of fungicidal composition

Abstract

The invention discloses a fungicidal composition containing boscalid and kresoxim-methyl and application of the fungicidal composition. The fungicidal composition takes boscalid and kresoxim-methyl as main effective ingredients, wherein the weight ratio of boscalid to kresoxim-methyl is (1-70):(1-50). The fungicidal composition can be used for preventing and controlling diseases of cereals, fruit trees and vegetables, has a high synergistic effect, overcomes and delays the fungicide resistance of pathogenic bacteria, is high in fungicidal speed and long in lasting period, reduces the application cost and has a prevention and control effect which is obviously superior to that generated when one fungicide of the fungicidal composition is used. The fungicidal composition can be used for preventing and controlling fungal diseases of crops and especially can be used for preventing and controlling the fungal diseases such as powdery mildew, gray mold, sclerotiniose, rot, venturia inaequalis, downy mildew, glume blotch, net blotch, rice blast, late blight and blight, and the effect is better than that generated when one fungicide is used.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with boscalid and kresoxim-methyl 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 fru...

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
