Sterilization composition containing fluxapyroxad and metominostrobin and its application

Abstract

The invention discloses a sterilization composition which takes fluxapyroxad and metominostrobin as main active components and its application, which belongs to the technical field of complex formulation pesticide. The sterilization composition takes the fluxapyroxad and metominostrobin as main effective components, wherein the weight ratio of fluxapyroxad to metominostrobin is 1-90: 1-90, and the mass percentage content of fluxapyroxad and metominostrobin accounts for 2-90% of that of the composition. The sterilization composition has obvious effect for preparing the medicine for preventing and treating the resistant plants fungal disease of cereals, fruit trees, vegetables and crops, and especially for preventing and treating powdery mildew, botrytis, sclerotinia rot, rot disease, rust disease, rot, net blotch, downy mildew, rice blast and fusarium patch, and especially for preventing and treating rice blast and powdery mildew of cucumber. Compared with a single dose, the prevention and treatment spectrum can be enlarged by the composition, the production and usage cost can be reduced, and the drug resistance can be overcome and delayed.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a bactericidal composition and its application, in particular to a bactericidal composition with flufenapyramide and fenoxystrobin as main active ingredients and its application. Background technique [0002] Fluxapyroxad, chemical name: 3-(difluoromethyl)-1-methyl-N-(3',4',5'-trifluoro[1,1'-biphenyl]-2-yl)-1H- pyrazole-4-carboxamide, molecular formula: C 18 h 12 f 5 N 3 O. The structural formula is as follows: [0003] [0004] Pyrazole amide fungicides are succinate dehydrogenase inhibitors, both for prevention and control. It can inhibit fungal respiration, inhibit spore germination, germination tube elongation, hyphal growth and sporulation. Can be used to control and suppress a variety of fungal diseases on a variety of crops. [0005] Metominostrobin, molecular formula: C 16 h 16 N 2 o 3 , chemical name (E)-2-methoxyimino-N-methyl-2-(2-phenoxyphenyl...

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
