Efficacy Test of 15% Pyridaben-acetamiprid Microemulsion to Control Phyllotreta vittuta in Raphanus sativus L.

为筛选出防治黄曲条跳甲的高效药剂,以哒螨灵微乳剂、啶虫脒乳油为对照,比较了不同用量哒螨灵·啶虫脒微乳剂对黄曲条跳甲的防治效果。试验结果表明,15%哒螨灵·啶虫脒3个处理(90.0、67.5、45.0 g/hm2)对黄曲条跳甲均具有良好的防治效果,药后3 d的防效最好,防治效果分别为97.17%、93.70%和90.63%,且具有较好的速效性,持效期为10 d左右。因此,15%哒螨灵·啶虫脒是防治黄曲条跳甲较为理想的药剂,建议与其他农药进行轮用。

In order to screen out efficient pesticides to control Phyllotreta vittuta, using pyridaben nficroemulsion and acetamiprid missible oil as control treatments, the control efficacy of different dosages of 15% pyridaben-acetamiprid microemulsion to P. vittuta were compared. The results showed that the 3 treatments （the dosages of pyridaben- acetanfiprid microemulsion was 90.0, 67.5, 45.0 g/hm^2 respectively ） had good control efficacy to P. vittuta The control effects were best and the control effects were 97.17%, 93.70% and 90.63%, respectively after 3 days of applying the pesticide. Meanwhile, it had a good quick-acting effect and the lasting effect period was about 10 days. Therefore, 15% pyridaben-acetamiprid microemulsion was an ideal agent to control P. rittuta and should be rotated used with other pesticides.
