摘要
为明确7种种衣剂对菜薹的安全性及对黄曲条跳甲的防控作用,为黄曲条跳甲的有效防控提供技术支持,采用田间试验研究了乙基多杀菌素、Bt、啶虫脒、唑虫酰胺、虫螨腈、高效氯氟氰菊酯+虫螨腈、高效氯氟氰菊酯+啶虫脒等7种药剂对菜薹出苗、株高、鲜重的影响及对黄曲条跳甲的防控作用。结果表明,7种种衣剂对菜薹安全。除高效氯氟氰菊酯+虫螨腈、高效氯氟氰菊酯+啶虫脒外,其他5种药剂对黄曲条跳甲均具有一定的防控效果,以唑虫酰胺防治效果最好,平均防效高于82%,植株受害率较低,小于5%。
The safety of seed coating agents,including spinetoram,Bt,acetamiprid,tolfenpyrad,chlorfenapyr,lambda-cyhalothrin＋chlorfenapyr and lambda-cyhalothrin＋acetamiprid,on the emergence,plant height and fresh weight of Chinese flowering cabbage was evaluated and their control effects on Phyllotreta striolata（Fabricius）were also investigated by field experiment.The results showed the seven pesticides were safe to Chinese flowering cabbage by seed coating.Except the lambda-cyhalothrin＋chlorfenapyr and lambda-cyhalothrin＋acetamiprid,the other 5 kinds of pesticides had certain control effect on P.striolata,among which tolfenpyrad was the best with the efficacy of more than 82% and the damaged rate of plant was lower than 5%.
