Composite synergic sterilization composition containing boscalid and bixafen and application thereof

Abstract

The invention discloses a composite synergic sterilization composition containing boscalid and bixafen and application thereof. The sterilization composition employs boscalid and bixafen as main effective components, and the weight ratio of boscalid to bixafen is 1-90:1-90. The sterilization composition is applicable to control diseases of cereal crops, vegetables and fruit trees, has relatively high cooperative synergic effect, helps to overcome and delay drug resistance of pathogens, is fast in sterilization speed, relatively long in persistent period and reduced in application cost, and has obviously better control effect than other singly-used reagents. The composite sterilization composition is applicable to control fungous diseases of crops, and especially applicable to fungous diseases such as wheat powdery mildew, grey mold, sclerotinia rot, rot disease, rust disease, septoria nodorum, net blotch, downy mildew, rice blast, damping-off disease and the like, and has relatively good effect than singly-used effective components.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a composite synergistic bactericidal composition with boscalid and bixafen 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, t...

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
