25％氰烯菌酯悬浮剂防治小麦赤霉病大田示范试验

摘要

In order to apply and extend the novel fungicide JS399-19, the field demonstration experiments of JS399-19 25% SC against wheat scab were carried out in Baimahu farm and Xinyang farm of Jiangsu province in 2010. The results showed that the control effects of JS399-19 25% SC against wheat scab were 80.10%-98.28% at the dosage of 1 500-2 250 g/hm2 and superior to carbendazim. The yields enhancement of JS399-19 25% SC was similar to carbendazim. JS399-19 should have beautiful prospect against wheat scab owing to excellent control effect and increase yield.%为了加快创制杀菌剂氰烯菌酯防治小麦赤霉病的应用推广,2010年在江苏省白马湖农场和新洋农场进行了大田示范试验.结果表明,25％氰烯菌酯悬浮剂1 500～2 250 g/hm2对小麦赤霉病的防治效果为80.10％～98.28％,均优于对照药剂40％多菌灵悬浮剂1 500 g/hm2处理,增产效果与多菌灵相当.氰烯菌酯对小麦赤霉病具有明显的防病和增产效果,应用前景良好.
