Composite synergy sterilization composition containing boscalid and trifloxystrobin, and applications thereof

Abstract

The invention discloses a composite synergy sterilization composition containing boscalid and trifloxystrobin, and applications thereof. The sterilization composition adopts boscalid and trifloxystrobin as main effective components, wherein a weight ratio of the boscalid to the trifloxystrobin is 1-90:1-90. The sterilization composition has the following characteristics that: the sterilization composition can be used for prevention and control of cereal plant diseases, fruit tree plant diseases and vegetable plant diseases, and has a high synergy effect, wherein drug resistance of bacterial is overcome and delayed, sterilization is rapid, an effect lasting period is long, an application cost is reduced, and a prevention and control effect is significantly better than a prevention and control effect of use of a single agent; and the sterilization composition can be used for prevention and control of fungal plant diseases in crops, particularly for powdery mildew, botrytis cinerea, sclerotium disease, rot disease, rust disease, glume blight, web blotch, downy mildew, rice blast, drooping disease and other fungal plant diseases, wherein the obtained effect is better than the effect of use of a single agent.

Description

Technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a compound synergistic bactericidal composition with boscalid and trifloxystrobin as main active ingredients and its application. Background technique [0002] Boscalid is a new nicotinamide fungicide developed by BASF in 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] This fungicide has a wide bactericidal spectrum and is active against almost all types of fungal diseases. It is very effective in controlling powdery mildew, gray mold, sclerotinia and various rot diseases, and is also effective against bacteria resistant to other chemicals. , for rape, beans, bulb vegetables, mustard greens, carrots, apples, lettuce, peanuts, potatoes, stone fruits, strawberries, nuts, cabbage, cucumbers, mint, peas, root vegetables, sunflowers, grapes...

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
