[Objective] To study keeping seedling effect of etnylicin under different concentration on Tussilago farfarae L..[Method] The local Tussilago farfarae L.stems were treated with low concentration(3 000 times),middle concentration(2 000 times) and high concentration(1 000 times) ethylicin,individually,and the ecdemic Tussilago farfarae was treated with high concentration ethylicin.Effects of different treating methods like root pouring and foliar spraying were comparatively studied.[Result] Before sowing,Tussilago farfarae L.treated with low concentration ethylicin was better in keeping seedling and ecdemic Tussilago farfarae L.showed higher seedling rate.At the early period of disease,Tussilago farfarae L.treated with middle concentration ethylicin using both root pouring and foliar spraying grew better.[Conclusion] Ethylicin showed keeping seedling effect on Tussilago farfarae L.,and foliar spraying would be better.
