摘要
为给种衣剂在燕麦上的推广应用提供依据,研究了吡虫啉和噻虫嗪两种种衣剂对燕麦蚜虫及红叶病的田间防治效果及增产作用。结果表明,两种种衣剂以4~6 mL/kg种子剂量一次性包衣后,对燕麦蚜虫和红叶病均有较好防效,在燕麦扬花期对麦蚜的防效大于50%,成熟期对红叶病的防效也在43%以上,增产效果显著。相比而言,吡虫啉种衣剂防治效果优于噻虫嗪。
Aphid and red leaf virus disease were considerded as major diseases and insect pests in oat production.In this study,the control effects of two insecticides imidaeloprid and thiamethoxam of flowable concentrate for seed coating on aphid and red leaf virus disease were investigated,and the effects of seed coatings on grain yield and yield components of oat also were studied.The results showed that the control effects of seed coating on aphid and red leaf virus disease were better with 4~6 ml·kg-1 doses,and t...
