摘　　要：纹枯病是水稻主要病害,为明确新药剂40%丙硫菌唑·戊唑醇悬浮剂混配对水稻纹枯病的防治效果,文章以嘉67和秀水121为供试水稻品种,以10%井冈霉素A可溶性粉剂为对照药剂,进行了大田试验。结果表明,不同浓度新药剂40%丙硫菌唑·戊唑醇悬浮剂混配9%吡唑醚菌酯微囊悬浮剂后,在2种水稻品种上均对水稻纹枯病有很好的防治效果,且在2种水稻品种中防治效果一致。不同浓度药剂试验均未见药害。从防治效果上看,50 mL新药剂40%丙硫菌唑·戊唑醇悬浮剂混配50 mL 9%吡唑醚菌酯微囊悬浮剂防治水稻纹枯病可以在当地推广应用。Sheath blight is the main disease of rice.In order to clarify the control effect of the new agent 40%prothioconazole·tebuconazole suspension on rice sheath blight,Jia 67 and Xiushui 121 were used as test rice varieties,10%Jinggangmycin A was used as the control agent,field tests were conducted.The results showed that the new agent 40%prothioconazole·tebuconazole suspension mixed with 9%pyraclostrobin microcapsule suspension had a good control effect on rice sheath blight on two rice varieties,and the control effect was consistent in the two rice varieties.There was no pesticide harm in the test of different concentrations.From the perspective of control effect,50 mL of the new agent 40%prothioconazole·tebuconazole suspension mixed with 50 mL 9%pyraclostrobin microcapsule suspension agent for the prevention and control of rice sheath blight can be popularized and applied locally.
