摘要
对20%银杏外种皮乳油和10%银杏外种皮水乳剂两种农药制剂进行了毒力和田间药效测定。结果显示20%银杏外种皮EC和10%银杏外种皮EW对萝卜蚜的LC50分别为1.39、2.56g/L。施药7d后,20%银杏外种皮EC5g/L和10%银杏外种皮EW10g/L对萝卜蚜、柑橘红蜘蛛的田间防效分别为93.5%、73.7%和95.3%、69.6%。
The toxicity and flied control efficiency of 20% EC and 10% EW of Ginkgo biloba L. sarcotesta were determined. The result showed 20% EC and 10% EW of Ginkgo biloba L. sarcotesta had high contact toxicity to Lipaphis erysimi, with the LD50 （or LC50） values of 1.39 g/L and 2.56 g/L, respectively. After treating of 7d, the control efficiency of 20% EC 5 g/L and 10% EW 10 g/L on Lipaphis erysimi, Panonychus cirri were 93.5%, 73.7% and 95.3%, 69.6%, respectively.
