A method of controlling fungal diseases of crops with cinnamate compounds, the cinnamate compounds having one of the following chemical structures:

##STR00001##

wherein the cinnamate compounds exhibit strong antifungal activities, have a broad antifungal spectrum against pathogenic fungi of crops, are safe for crops, can avoid the occurrence of phytotoxicity, and can be used for the control of fungal diseases of crops such as powdery mildew, damping-off, rot, gummy stem blight, anthracnose, white rot, northern leaf blight, late blight, gray mold, downy blight, blight, early blight, Fusarium wilt, full rot, Pythium rot, dry rot, ring spot, sheath blight, stalk break and the like, the field efficiencies of which are superior to or comparable to that of the control compound, methyl 3,4-dimethoxy cinnamate.
