摘要：

摘 要：为进一步明确现有阿维菌素与其它杀螨剂的混剂对柑桔红蜘蛛的效果。2009年,在大田中，以喷雾施药法对17种阿维菌素混配剂进行了防治柑桔红蜘蛛的田间试验。结果表明：用药后3d，对柑桔红蜘蛛控制效果≥90%的品种有14种；用药后10d，控制效果≥90%的品种有12种；速效最好的是10%阿维菌素?哒螨灵EW，用药后1d，防治效果达97%以上；持效期最长的是25%阿维菌素?苯丁锡WP，用药后30d，防治效果仍达86%以上。可以认为，阿维菌素与其它杀螨剂合理的混配，将是今后控制柑桔红蜘蛛为害的最为经济有效品种。

Abstract:

Abstract: The control effect of 17 type abamectin mixtures against Panonychus citri were tested in orange through field spray. The results showed that, 3 days after single spray, 14 mixtures got control effect above 90%. Ten days after single spray, 12 mixtures got control effect above 90% .The mixture of 10% abamectin－pyridaben EW got the quickest response and a control effect of above 97% was observed one day after spray. The longest lasting effect was from 25% abamectin-fenbutatin oxide WP and 86% control effect still existed after 30 days of spray. It was concluded that, reasonably mixture of abamectin with other acaricides could effectively prevent the attack by Panonychus citri in orange.
