Abstract

A composite agricultural chemical for preventing and treating the hypochnus, rotten meck and green smut of paddy rice contains hexaconazole and jianganmycin. Its advantages are high synergistive effect and low by-effect.

Description

technical field [0001] The invention relates to a new medicine for preventing and treating rice sheath blight, rice blast and rice false smut. Background technique [0002] Rice sheath blight is a common and frequently-occurring disease of rice in my country. The disease was first reported by Wei Jingchao in 1934. Now all over my country's rice areas, generally the south is heavier than the north, and the annual occurrence area is about 1-2 billion mu. Light ones can reduce production by 5-10%, and heavy ones can reach 50-70%. The control of rice sheath blight mainly relies on chemical agents. Before the early 1980s, the special medicine Daojiaoqing was used, but Daojiaoqing is a kind of organic arsenic preparation, which not only pollutes the environment, but also easily causes phytotoxicity (failure to earing) during the rice booting stage, so it is banned by the country. After Daojiaoqing was banned, the main alternative agent was Jinggangmycin. Jinggangmycin is a cl...
