Fungistatie test in lab and outdoor control to pathogenic fungi in some kinds of vegetables by using ginkgolie acids mieroemusion were eondueted. The results showed that inhibition rate of ginkgolie aeids mieroemusion on pathogenie hypha of cabbage anthraenose, eueumber wilt disease, eabbage altemaria leaf spot, eggplant Selerotium rolfsii and Rhizoetonia solani were 96.7%, 93.0%, 100% ,, 100% and 100% respeetively under indoor condition when the concentration of ginkgolie aeids mieroemusion was 5 mg/mL; the inhibition rate on the above fungi were all 100% when the concentrations of ginkgolie aeids mieroemusion were or more than10 mg/mL; under outdoor condition, the inhibition rate to pathogenic hypha of cabbage anthraenose, cabbage alternaria, leaf spot, eueumber wilt disease, eggplant Rhizoetonia solani were 72.0%, 77.9%, 71.4% and 73.4% respeetively when the concentration of ginkgolie acids mieroemusion were 1 mg/mL and were slightly lower than that inhibition rate by using 800 times of 50% carbendazim solution.%进行银杏酸微乳．剂对蔬菜真菌的室内抑菌与室外防治试验，结果表明：银杏酸微乳剂5mg／kg对白菜炭疽病、黄瓜枯萎病、甘蓝黑斑病、茄子白绢病、茄子立枯病等5种病菌菌丝的抑菌率分别为96．7％、93．0％、100．0％、100．0％、100．0％；银杏酸微乳剂10mg／mL以上对5种病原菌菌丝的抑菌率均达到100．0％。银杏酸微乳剂1mg／mL对白菜炭疽病、甘蓝黑斑病、黄瓜枯萎病、茄子立枯病等4种蔬菜病害的田间防治效果分别为72．0％、77．9％、71．4％、73．4％，略低于50％多菌灵800倍液的防效。
