氟啶虫胺腈与乙基多杀菌素混用防治水稻迁飞性害虫田间药效试验

Field Effect Trials on the Mixture of Sulfoxaflor and Spinetoram Against Rice Migratory Pests

为探索防治水稻迁飞性害虫的有效药剂,开展了田间药效试验。结果表明:22%氟啶虫胺腈悬浮剂与60 g/L乙基多杀菌素悬浮剂混用防治稻飞虱、稻纵卷叶螟具有速效性好、持效期长的特点,可起到防治多种害虫的作用,其适宜剂量为22%氟啶虫胺腈悬浮剂375 mL/hm2+60 g/L乙基多杀菌素悬浮剂500 mL/hm2,对水稻生长无任何不良影响,且对稻田害虫天敌如蜘蛛、黑肩绿盲蝽等杀伤作用小。

In order to find excellent insecticides for controlling rice migratory pests, the field trials were carried out. The results showed that the mixture of sulfoxaflor 22% SC and spinetoram 60 g/L SC had high, quick and long control effects against rice planthopper and rice leaf roller, and was safe to the main natural enemies such as spiders and Cyrtorrhinus livdipennis, etc. The application rates of the mixture were sulfoxafior 22% SC 375 mL/hm2 and spinetoram 60 g/L SC 500 mL/hm2.
