Title:
USE OF HYDROXYCARBOXYLIC ACID COMPOUNDS FOR CONTROLLING PLANT DISEASES
Document Type and Number:
WIPO Patent Application WO/2020/253076
Kind Code:
A1
Abstract:
Discloses the use of a hydroxycarboxylic acid compound for controlling plant diseases by fungi and oomycetes, wherein the hydroxycarboxylic acid compound is selected from compounds of formulas (I), (II), (III) and (IV), as well as isomers, hydrates or salts thereof. The hydroxycarboxylic acid have remarkable inhibitory activity against appressorium formation of fungi or oomycetes, and therefore, can be used for preventing plant diseases, such as rice blast, anthracnose, gray mold, downy mildew, phytophthora blight, etc., with no obvious phytotoxicity and good safety. Compared with compounds currently available for controlling plant diseases such as rice blast, anthracnose, gray mold, downy mildew, phytophthora blight, etc., the hydroxycarboxylic acid compounds have characteristics such as good preventive effect, environmental friendliness, non-toxicity, low residue, and safety.
