摘要

The control effects of six kinds of reagents against rice sheath blight were compared in the test.The results showed that 24% thifluzamide SC 300 mL /hm 2 and 20% Jinggangmycin.prochloraz WP 750 g /hm 2 had good control effect against rice sheath blight,and their control effects after spraying for 7 and 14 d were 72.16%,77.91% and 66.52%,71.08%,respectively.The control effects of both reagents were significantly better than other test reagents and control reagent Jinggangmycin,and they had no adverse effect on growth and development of rice.Considering from the aspects of control effect and economy,20% Jinggangmycin.prochloraz WP was suggested to be used to control rice sheath blight,its recommended dosage was 600-750 g /hm 2,and the reagent volume was 750kg with coarse spraying.
