Anti fungal efficiency of extract from exopleura of Ginkgo Biloba L on crops was evaluated in the present study. Results showed that the extract at concentration of 0.20 g·mL-1 (in water) exhibited an obvious anti-growth effect against fungi of C.orbiculare, Rhizoctonia solani K and bacterium of Pseutomoas solanacearu,respectively, while the extract at the concentration of 2.0 mg·mL-1 ( in water) also had reduction of death rate for potted tomato seedlinges that caused by Pseutomoas solanacearum.
