Abstract

The invention relates to a sterilization composition, in particular to a sterilization composition containing tebuconazole and dimetachlone with a synergistically effective amount; wherein, the weight ratio of tebuconazole to dimetachlone is 100:1 to 1:20 preferably, more preferably 50:1 to 1:10, most preferably 9:1 to 1:1. The sterilization composition is applied to preventing the rice sheath blight disease and rice false smut in particular.

Description

technical field [0001] The invention relates to a fungicidal composition for preventing and treating rice sheath blight and rice smut. More specifically, the present invention relates to a fungicidal composition containing tebuconazole and sclerotin and the use of the composition for preventing and treating rice sheath blight and rice false smut. Background technique [0002] Rice sheath blight and rice false smut are the main diseases in rice production. Rice sheath blight occurs in major rice-growing areas in the United States, South America, Europe, and Africa. The disease is more severe in South China, Central China and East China, and also occurs in North China, Northeast China and Yunnan rice fields, and it is more serious in some areas. Generally, the production of the disease is reduced by 5-10%, and the production of severe fields is reduced by 50-70%. Rice false smut occurs in all rice-growing regions in my country, and rice false smut can cause yield loss, and m...
