Disclosed is the use of a dicarboxylic acid compound for controlling plant diseases by fungi and oomycetes, wherein a dicarboxylic acid compound is selected from compounds of formulas (I), (II), (III) and (IV), as well as isomers, hydrates or salts thereof. The dicarboxylic acid compounds have remarkably inhibitory activity against appressorium formation by fungi or oomycetes, and therefore, can be used for controlling diseases, such as rice blast, anthracnose, downy mildew, phytophthora blight, gray mold, etc., with no obvious phytotoxicity and good safety. Compared with fungicides currently used for controlling plant diseases such as rice blast, anthracnose, downy mildew, phytophthora blight, gray mold, etc., the dicarboxylic acid compounds have characteristics such as good preventive effect, environmental friendliness, non-toxicity, low residue, and safety.
