摘要
【目的】评估咯菌腈·精甲霜灵·噻虫嗪悬浮种衣剂口sc）对棉花猝倒病、棉花立枯病、棉花蚜虫及玉米灰飞虱、玉米茎基腐病的防治效果。【方法】以咯·精甲·噻Fsc4个有效成分量和25g/L咯菌腈FSC等4种对照药剂各1个有效成分量，进行田问药效对比试验。【结果】咯·精甲·NFSC对棉花、玉米病害的防效为53．22％～80．22％，对蚜虫、飞虱的防效为63．62％-92．68％。瞄论1287．4g／g/L·精甲·gFSC防治棉花病虫害推荐使用有效成分量172．5-258．75g/100kg种子。361．68g／L咯·精甲·噻FSC防治玉米病虫害推荐使用有效成分量108．5-162．g/100kg种子。
[Aims] This study aims to evaluate the control effect offludioxonil,metalaxyl-M＇thiamethoxam suspension concentrates as seed dressing against cotton and maize diseases and insect pests. [Methods] The contrast tests were carried out among fludioxonil ,metalaxyl-M ＂thiamethoxam FSC at four doses and four kinds of reagents such as fludioxonil FSC at one dose. [Results] The results indicated fludioxonil ＂metalaxyl-M ~thiamethoxam FSC showed 53.22-80.22% field control efficacy against cotton and maize diseases and 63.62-92.68% field control efficacy against cotton and maize insect pests. [Conclusions] The recommended usage of fludioxonil＂ metalaxyl-M · thiamethoxam FSC is 172.5-258.75 g per 100 kg seeds of 287.4 g/L against cotton diseases and insect pests, and it is 108.5-162.8 g per 100 kg seeds of 361.68 g/L against maize diseases and insect pests.
