摘要

[Objective]The paper was to study the field fficacy of several fumgicide against rice sheath bligh(Rhicoetonia solm).[Method]Field efficacy trial was performed with three novel fungicides,75%tebuconazole.azxytrobin WG,75%tifloxystrobion-tebuconazole WG and 24%6 thi-fluzamide sC,while 30%difenoconazole-propiconazole EC and 10%jingangmyein AS,which had been Long circulated in production,were uwsed as contrl agents.[Result]The three novel fungicides had better control ffe on sheath blight than the control agents;75%tebuconazole.azoxys-trobin WG at the dase of 20 g/667 m2 received the best contrl efect,and the control efect was still 87.72%at 20 d post administration,and the yield increase efect was remarkable.The control efects of 75%tiloxystrobin-tebuconazole wG and 24%thifluzamide SC were 85.67%and 87.36%,repectively.[Conclusion]75%tebuconazole.azxoxystrobin wG,75%tifloxystrobin tebuconazole WC and 24%thiluamide SC could be promted as rotation fungicides to control rice sheath blight.
