Study on Antifungal Activity of Some Medicinal Plants against Gray Mold （Botrytis cinerea）

摘要

In order to investigate antifungal effect of medicinal plant extracts on Botrytis cinerea,the antifungal activity of ethanol extracts of 8 medicinal plants including Ginkgo biloba against Botrytis cinerea was determined by growth rate method. The results showed that Ginkgo biloba and Cinnamomum cassia extracts had significant inhibition effects on B. cinerea mycelium growth( P < 0. 05),with inhibition rates over 70% and EC_(50) values of 0. 027 mg / ml and 0. 039 mg / ml,respectively,significantly different from the antifungal effects of other kinds of medicinal plants; and P. ternata and A. tsaoko extracts showed the second highest inhibition effects,with EC_(50) values of 0. 011 9 and 0. 039 3 mg / ml,respectively. Further experimental application could be carried out.
