通过试验确定了以狠毒、萱草根和荚竹桃等１８种杀虫植物配制成的制剂“棉铃清”水剂。该药剂２００～３００倍药液处理，对棉铃虫［Ｈｅｌｉｏｔｈｉｓａｒｍｉｇｅｒａ（Ｈｕｂｎｅｒ）］２～３龄幼虫的校正死亡率为１００％～９５．６％；对危害苹果树的棉铃虫的田间防治效果为９１．３％～９６．５％，比３０％灭铃灵乳油１２００倍液的防治效果略好；果实受害果率控制在２．０％以下，仅为清水空白对照值的１０％左右。 Through experiments, we determined that the formulation of “cotton bollworm” agent is made of 18 kinds of insecticidal plants such as vicious, hemerocallis root and pod. The pesticide 200-300 times solution treatment, the correct mortality of Heliothis armigera (Hubner)] 2 ~ 3 instar larvae was 100% ~ 95.6%; the field control effect on the cotton bollworm that harm the apple tree was 91 .3% ~ 96.5%, which was slightly better than the control of 30% TCS 1200 times; the fruit damage rate was below 2.0%, only about 10% of the control value of fresh water.
