摘　　要：以辽细辛精油为试材,黄瓜灰霉病菌为目标菌,采用菌片接种法,测定了辽细辛精油对黄瓜灰霉病的活体药效和离体药效,以期探讨辽细辛精油的实用性,为植物源杀菌剂的开发提供理论依据。结果表明:辽细辛精油对黄瓜灰霉病既有保护作用也有治疗作用,且随着精油浓度的升高药效逐渐提高;辽细辛精油的保护作用优于治疗作用,在活体条件下,保护和治疗作用的EC50分别为1 033.30mg·L^(-1)和1 038.31mg·L^(-1),充分体现了"预防为主"的植保理念。The asarum essential oils was used as test materials, cucumber Botrytis cinerea as the target germ, adopted inoculative method with pathogen piece,the indoor efficacy of asarum essential oils against cucumber gray mold in vivo and in vitro were studied. In order to explore the practical applicability of the asarum essential oils and provide the theory basis for the development of plant source disinfectant. The results showed that the efficacy of asarum essential oils included protective action and therapeutic action against cucumber gray mold,and with the increase of asarum essential oil concentration,the efficacy was gradually increased. While protective action were superior to therapeutic action of asarum essential oil. Both of the EC50 were 1 033. 30 mg·L-1 and 1 038. 31 mg·L-1 in vivo, which showed the concept of prevention first.
