Rice sheath blight is one of the three diseases of rice. The commonly used pesticide rice foot green although the better results, but more stringent application period, during heading rice spraying, the phytotoxicity heavier, prone to not strong phenomenon. Jinggangmycin is an antibiotic that is screened against the sheath blight of rice in Shanghai Institute of Pesticide Science. It is similar to that of Japan. In 1974, we conducted field trials on greenhouses and field large-area curatives, spraying times, spraying rates and duration of efficacy in our hospital farm and north farm in Xiaoshan County. The field trial area was 9.47 mu.
