Abstract
The antifungal activity of acetone extracts from forty weeds against three phytopathogenic fungi including Phytophthora capsici Leonian,Fusarium oxysporium Schl.and Botrytis cinerea Pers.was studied in vitro.The results showed that the acetone extracts from seven weeds had an inhibition rate of above 60% against at least one of the tested fungi.The inhibition rates of the acetone extracts from Artemisia annua L.,Xanthium sibiricum Patrin and Salvia plebeia R.Br.were all higher than 60% against the three fungi.The inhibition rate of the acetone extracts from Eclipta prostrata L.was higher than 60% against P.capsici and F.oxysporium.The acetone extracts from Plantago asiatica L.,Lagopsis supina(Steph.)IK.-Gal.and Euphorbia helioscopia L.had a significant antifungal activity against B.cinerea.
