PURPOSE: A composition containing a fermented ginkgo exocarp extract is provided to be applied to barley powdery mildew, leaf rust, late blight, or gray mold, and to ensure safety without being harmful to human body. CONSTITUTION: A composition for preventing plant diseases contains 0.0001-30.0 wt% of fermentation of ginkgo exocarp, or a fermented ginkgo exocarp extract as an active ingredient, which is prepared by using a microorganism. The microorganism is selected from the group consisting of yeast, lactic acid bacteria, and bacillus bacteria. A method for preparing the fermentation comprises: a step of extracting the ginkgo exocarp with one or more solvents selected from purified water, methanol, ethanol, glycerin, ethyl acetate, butylene glycol, propylene glycol, dichloromethane, and hexane； and a step of concentrating by reduced pressure and freeze-drying.본 발명은 은행 외과피를 포함하는 배지에 발효 미생물을 접종하여 발효한 은행 외과피 발효물을 추출하여 얻은 은행 외과피 발효추출물을 유효성분으로 함유하는 것을 특징으로 하는 식물병 방제용 조성물에 관한 것으로, 본 발명의 식물병 방제용 조성물은 보리 흰가루병, 밀 붉은녹병, 토마토 역병 또는 토마토 잿빛곰팡이병에 매우 뛰어난 방제 효과를 가진다.
