Sterilization composition containing flutolanil

Abstract

The invention provides a sterilization composition comprising the following active components with effective quantity: flutolanil and one of triazole class compounds of hexaconaole, ethyltrianol, diniconazole, triazolone, triadimenol, epoxiconazole, fluquinconazole, flusilazole, systhane, penconazole, tetraconazole, biphenyl triadimenol and cyclopropyl hexaconazole. The composition can be used forpreventing and treating diseases caused by rhizoctonia and has the following advantages: (1) mixed matching has an obvious synergistic action, and the preventing and treating effect is enhanced; (2)the function mechanisms of two active components in the composition are different, the single selection pressure of pathogenic bacteria is lightened, and the composition is beneficial to overcoming the generation of the drug resistance of the pathogenic bacteria and delaying the generation speed of resistibility; (3) the preventing effect is obviously enhanced after the medicaments are mixed and matched, and the use quantity of the effective components is reduced, thereby the cost is lowered and environmental pollution is lightened; and (4) preventing and treating spectra are expanded, the composition also has a treating function to other diseases, and can treat multiple diseases.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a bactericidal composition, in particular to a synergistic bactericidal composition containing fluoroamide. Background technique [0002] Rice sheath blight and wheat sheath blight caused by Rhizoctonia sp. are worldwide diseases with wide distribution and serious damage. They mainly survive the winter in the soil with sclerotia and become the primary infection source of the next year's disease. In recent years, with the changes of crop varieties, cultivation systems and fertilizer and water conditions, the damage of sheath blight has increased year by year, which has brought great losses to rice and wheat production. Chemical control is the main means of plant disease control. However, the currently used fungicides such as carbendazim and thiophanate-methyl have poor control effects. At the same time, due to long-term excessive use of these agents, the bacteria have developed d...
