摘  要：
以制川乌、钩吻、透骨草和远志4种中药为试材,采用乙醇超声提取、大孔吸附树脂纯化的方法制得提取物,通过菌丝生长速率法研究了各提取物对番茄灰霉病菌菌丝的抑制作用,以期为番茄灰霉病的综合防治提供参考依据。结果表明:各提取物对番茄灰霉病菌菌丝均有抑制作用,并且抑制率随着提取物浓度的升高而升高。制川乌、钩吻、透骨草和远志提取物的EC50分别为2.703 8、3.273 7、8.482 9、12.406 0 mg·m L-1。盆栽防治试验结果表明,制川乌提取物的防治效果随着提取物浓度的升高而升高,在20 mg·m L-1时保护防效达到了76.43%,治疗防效达到了66.67%,与药物啶酰菌胺的保护和治疗防效相当。

摘  要：
Taking Aconitum carmichaeli,Gelsemium elegans,Phryma leptostachya and Polygala japonica as test materials,extracts from the four Chinese herbs were prepared by ethanol ultrasonic extraction and then macroporous resin purification. Mycelium growth rate method was used to test inhibitory effect of these extracts against Botrytis cinerea,which could provide reference basis for the prevention and control of tomato gray mold.The results showed that all extracts had effects on mycelium growth of Botrytis cinerea,and inhibition rates were improved when concentration of extracts rose. The 50% effective concentrations( EC50) of Aconitum carmichaelii,Gelsemium elegans,Phryma leptostachya and Polygala japonica extracts were 2. 703 8 mg ·m L-1,3. 273 7 mg·m L-1,8. 482 9 mg·m L-1 and 12. 406 0 mg·m L-1,respectively. In pot trials,with the increase of the concentration of Aconitum carmichaelii extract,the control effect against tomato gray mold was improved. At 20 mg·m L-1,the protective effect reached 76. 43%,and therapeutic effect reached 66. 67%,which were equivalent to the protective and therapeutic effect of boscalid.
