国槐叶小蛾幼虫化学防治试验研究

The Salvinia Natans Chemical Control Experiments of the Moth Larvae

该文研究了3种化学药剂不同施药剂量对国槐叶小蛾幼虫的防治效果。结果表明:试验使用的3种化学药剂中,50%杀螟松乳油以1000倍液处理校正死亡率最高,50%马拉硫磷乳油1500倍液处理校正死亡率最高,40%乙酰甲胺磷乳油以1500倍液处理校正死亡率最高。根据研究结果,生产上推荐50%杀螟松乳油1000倍液、50%马拉硫磷乳油和40%乙酰甲胺磷乳油1500倍液防治国槐叶小蛾幼虫。

Control effect of three kinds of chemicals in different dosages on the leaf small moth larvae was studied.It shows that the experiment using three kinds of chemicals,50% fenitrothion,1000 times liquid handling correction rates are highest,marla sulfur was 50% mortality rates times 1500 times liquid handling correction,40% acephate was dealt with correction rates are highest in a 1500 times liquid.According to the results,recommendations on production 50% fenitrothion ec 1000 times liquid,marla sulfur was 50% and 50% acephate was 1500 times liquid,salvinia natans little moth larvae.
