| Abstract: | Endophytic fungus strain 2B was isolated from the phloem of the root of Celastrus angulatus.The bioassay showed that the extracts of strain 2B fermentation products had certain degree fungicidical activity against Botrytis cinerea,Alternaria longipes,Glomerella cingulata,Exserohilum turcicum,Alternaria solani,the inhibiting ratio against pathogen growth was ranging from 62.5%-87.2%.Based on its morphological,cultivation and physiological characteristics,strain 2B was identified as Fusarium proliferatum. |
