Abstract: [OBJECTIVE] The new plant fungicide will benefit the effective control of the disease caused by Colletotrichum lagenarium. [METHOD] Thirty four species of 80% ethanol plant extracts (PE) stored for six months were tested against C. lagenarium by using growth rate and WA flat germination. [RESULTS] The inhibitory rate of 11 PE against conidium germination of C. lagenarium was higher 60% (for example, Glycyrrhiza yralensis, Lycium barberum and Desmodium styracifolium) as the concentration 0.01g/ml. Especially, the G. yralensis showed the strongest inhibitory effect on it with inhibitory rate of 99.6%. The inhibitory rate of 12 PE against mycelium growth and 15 PE against appressorium formation of C. lagenarium was higher 50%, respectively. [CONCLUSION] The most PE showed inhibition to C. lagenarium. On the control, only several PE had obviously inhibitory effect on the conidium germination, mycelium growth and appressorium formation at the same time.
