种子处理对棉花苗蚜的防治效果及对苗期生长的影响
|
摘要
[目的]明确杀虫剂种子处理对苗蚜防效及棉花苗期生长发育的影响。[方法]包衣、拌种和沟施处理,比较了4种药剂对苗蚜的防效及对株高、真叶数的影响。[结果] 30%噻虫嗪FS 12.0 g/kg、70%噻虫嗪WS 4.0 g/kg、2%吡虫啉GR 30 000.0 g/hm2和600 g/L吡虫啉FS 8.0 g/kg为4种药剂的最佳制剂用量,播后35 d的防效分别为84.0%、89.1%、76.7%、76.7%,噻虫嗪对苗蚜的防效优于吡虫啉;种子处理对株高均有一定的抑制作用,施用量越高抑制越明显,除70%噻虫嗪WS 6.0 g/kg,其他施用量对真叶生长具有促进作用。[结论]种子包衣或拌种对苗蚜有很好的防效,该地区棉蚜对吡虫啉敏感性降低,可选择噻虫嗪进行轮换使用。
[Aims] This study aims to clarify the control effects of seed treatment with insecticide to Aphis gossypii and its effects on cotton growth.[Methods] The effects of thiamethoxam and imidacloprid on control efficacy,plant height and true leaf growth were compared by different application methods of seed coating,mixing and furrowing.[Results] Field experiments showed that seed treatment with thiazide or imidacloprid had better control effects to A.gossypii.The control efficacy of thiamethoxam was better than imidacloprid.At 35 days after planting date,thiamethoxam 30% FS12.0 g/kg,thiamethoxam 70% WS 4.0 g/kg,imidacloprid 2% GR 30 000.0 g/ha and imidacloprid 600 g/L FS 8.0 g/kg were at the best dosage of four pesticides,their control efficacy on A.gossypii was 84.0,89.1,76.7 and 76.7%,respectively.Seed treatment had inhibitory effects on cotton height,and the higher of the application dosage,the more obvious of the inhibitory effects.For true leaf growth,seed treatments had promoting effects except thiamethoxazine70% WS 6.0 g/kg.[Conclusions] The seed coating or mixing had good control effect on A.gossypii,but the sensitivity in this area decreased to imidacloprid,so thiamethoxam could be selected for pesticide rotation.
