摘要
利用3%高渗苯氧威乳油4 000倍、1.2%苦.烟乳油1 500倍、绿得宝2 500倍喷雾防治松阿扁叶蜂初孵幼虫,可获得良好的防治效果。利用3%高渗苯氧威乳油+柴油1∶20喷烟防治松阿扁叶蜂初孵幼虫,施药后3 d幼虫死亡率达到91.9%。具有省事、高效、无污染的优点。
In the hatching period, 3.0% fenoxycarb in 4000 times or 1.2% matrine nicotine in 1500 times or Ludebao in 1500 times were sprayed against the larvae in trees, generating a good effect. Substituted by 3.0% fenoxycarb and diesel oil in a ratio of 1： 20, the mortalities of larvae were 91.9% in 72 hours. This technique is convenient and pollution-free.
