Abstract

The invention relates to a sterilization composition in the field of pesticide preparation. The active ingredients of the sterilization composition include tetraconazole and simeconazole which are mixed, wherein the weight percent ratio of the two active ingredients is (80:1)-(1:80), preferably (50:1)-(1:50); the total content of the active ingredients in the sterilization composition in percentage by weight is 1-90%, preferably 5-50%; and other components in the sterilization composition are allowed and acceptable auxiliary components. The sterilization composition containing tetraconazole and simeconazole can be prepared into wettable powder, suspending agent, missible oil, soluble liquid, emulsion in water and water dispersible granules; and the sterilization composition provided by the invention is mainly used for preventing and controlling diseases caused by erysiphe, puccinia, rhynchosporium, pyrenophora and septoria.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition compounded with tetraflumezole and silfluzole as active ingredients. Background technique [0002] Silfluazole, chemical name (RS)-2-(4-fluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-trimethylsilylpropane-2- alcohol. The silicon-containing triazole fungicide developed for Japan Sankyo Company is an ergosterol synthesis inhibitor, but its mechanism of action is relatively unique. The agent has excellent root absorption and migrates upward in the crop body, so it has good crop Endosmotic migration and bactericidal effect, it has a wide bactericidal spectrum, it has high antibacterial activity against ascomycetes, basidiomycetes and many incomplete fungi, and can prevent and control many diseases at the same time. In the past, triazole pesticides usually inhibited the growth of rice, but silfluazole especially has excellent control effects on ri...
