| 摘 要： | 对中草药大黄提取液防治黄瓜白粉病的保护活性、稳定性、持效期及押菌谱等作了初步研究。结果表明，大黄提取液的100倍液防效迭90％以上，优于粉锈宁(15％WP)1000倍液的防效(73．41％)；其酸碱稳定性与热稳定性都非常强；保护作用的持效期至少可达6d；押菌谱测试结果表明，它对供试的小麦根腐病菌Cochliobolus sativus等20种真菌都表现出一定的抑制作用。

| Abstract: | In this paper, the extract from Rheum palmatum was tested for prevention effect on powdery mildew of cucumber,stability,duration of the efficacy and restraint spectrums of fungi.The results demonstrated that 100-fold Rheum palmatum extraction was effective to control the disease and its efficacy was superior to 15% WP Triadimefon 1000-fold,which was up to 90.14%. The efficacy was stable in different temperatures and pH values.The duration of the preventive efficacy of Rheum palmatum extraction to S.fuliginea could last over 6 days,and also significantly to restrain many other fungi such as Cochliobolus sativus,Exserohilum turcicum ,et al. |
