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

Abstract

The present invention discloses a sterilization composition adopting fluxapyroxad and difenoconazole as main active components, and an application thereof, and belongs to the technical field of compounded pesticides. According to the present invention, the sterilization composition adopts fluxapyroxad and difenoconazole as main active components, wherein a weight ratio of the fluxapyroxad to the difenoconazole is 1-90:1-90, and the total amount of the fluxapyroxad and the difenoconazole is 2-90% of the mass of the sterilization composition; and the sterilization composition provides significant effects for preparation of drugs for prevention and control of crop resistance plant fungous diseases of cereals, fruits and vegetables, and specifically for preparation of sterilization drugs for prevention and control of powdery mildew, botrytis cinerea, sclerotinia rot, rot disease, rust disease, glume spot of rice, web blotch, downy mildew, rice blast, seedling blight and scab of cucurbits, especially sterilization drugs for prevention and control of pear scab of cucurbits and cucumber powdery mildew. In addition, compared with the single-agent substance, the composition has characteristics of prevention and control spectrum expanding, production and use cost reducing, and drug resistance overcome and delaying.

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 flufenapyroxad and difenoconazole 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] Difenoconazole (difenoconazole), molecular formula: C 19 h 17 Cl 2 N 3 o 3 , chemical name: cis, trans-3-chloro-4-[...
