摘要
为明确种子处理防治玉米瑞典蝇的效果,对吡虫啉、锐胜和灭蝇胺3种药剂按不同有效剂量进行了药效对比试验。结果表明:试验剂量条件下,3种药剂对玉米出苗均无不良影响。其中,70%锐胜湿拌剂拌种防治效果较好,可以达到90%以上;50%灭蝇胺可湿性粉剂效果最差,不适合作拌种剂使用。生产上应用70%吡虫啉0.2%～0.4%有效剂量拌种较为经济、高效。
The effects of seed dressing with imidacloprid,Tkiametkoxam and cyromazine on controlling frit fly in maize field were studied.The results showed that all pesticides had no harmful effects on emergence.The effect of 70% Thiamethoxam was better,which could be more than 90%,that of 50% cyromazine was the worst,which was not recommended as seed dressing agent.Using 70% imidacloprid with effective doses of 0.2%～0.4% as seed dressing agent in production was economical and efficient.
