Problems solved by technology

[0005] 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 resist

Abstract

The invention discloses a pesticide composition for preventing and treating plant diseases and a preparation method thereof. Bixafen and fluazinam are taken as active components of the pesticide composition; auxiliary materials or carriers acceptable on pesticide preparations are added into the pesticide composition, then the pesticide composition can be prepared into various conventional pesticide preparations. Formula screening tests show that the pesticide composition prepared by mixing bixafen with fluazinam has a synergistic effect of preventing and treating plant pathogen bacteria; fieldpesticide effect test results further prove that an obvious synergistic effect of preventing and treating strawberry anthracnose by mixing bixafen with fluazinam according to different ratios. The pesticide composition provided by the invention is capable of improving the effect of preventing and treating the plant diseases, prolonging the pesticide effect lasting period and reducing pesticide application cost, the pesticide composition is high in safety on crops, excellent in quick-acting property, long in effect lasting period and low in application cost, and meets the requirement on the safety of the pesticide preparations.

Description

technical field [0001] The present invention relates to a pesticide composition, in particular to a pesticide composition for preventing and treating plant diseases composed of bixafen and fluazinam as active ingredients and a preparation method thereof. The present invention further relates to various pesticides prepared from the pesticide composition. The pesticide preparation and its application in killing plant pathogenic bacteria belong to the field of pesticide composition for killing plant pathogenic bacteria. Background technique [0002] Bixafen (Bixafen) is an SDHI fungicide developed and listed by Bayer. It is a succinate dehydrogenase inhibitor, and its chemical formula is: C 18 h 12 Cl 2 f 3 N 3 O, its chemical name is: N-(3′,4′-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1-methylpyrazole-4-carboxamide , whose structure is figure 1 shown. [0003] Bixafen is a new type of broad-spectrum, protective and therapeutic activity of both systemic fungicid...
