Phytotoxin Produced by Nimbya scirpicola

Abstract

A phytotoxic substance isolated from the weed pathogen Nimbyascirpicola was identified as depudecin by spectral data analyses. It was found that depudecin had phytotoxic activity toward the hostplant of this fungus, kuroguwai, and toward other tested plants, and inhibited the root elongation of lettuce seedlings.
