This paper focuses on the selection of effective botanical pesticides to control A. lucorum and E. apicalis. This experiment explores the effect of several botanical pesticides for A. lucorum and E. apicalis, including the 0.5% veratrine, the0.6% Oxygen·Lactone agent, the 5% natural pyrethrin, the composite neem pesticide, the rotenone and the composite nicotine. The 0.5% veratrine shows a stable control efficacy, which is higher than 60% in Chengdu, while the composite nicotine shows the highest efficacy against A. lucorum, which is above 70%. In Yinchuan,the 0.5% veratrine shows the highest efficacy, against the first generation adults and the second generation larvae of E. apicalis, while the 5% natural pyrethrin shows 100% control efficacy against E. apicalis in Nanjiang. The 0.5% veratrine and the composite neem could be used as effective pesticides to control A. lucorum and the 5% natural pyrethrin can be used to control E. apicalis. They could be widely used in the production of pollution-free grapes.展开更多
