Abstract:	2,3-Dihydro-5-hydroxyl-2-methyl-4H-1-benzopyran-4-one, was isolated from 3 week old rice cultures of Phialophora gregata, a soybean pathogen, grown at 25 degrees C. This material in repeated bioassays prevented callus formation on soybean hypocotyl sections at 100 and 200 microgram/ml callus culture medium. This is the first report of the production of this metabolite by a member of the Phialphora genus and of its toxicity to soybeans.
