Rumex dentatus L. is a problematic weed of wheat. Bioassay-directed isolation of culture filtrates of a plant pathogenic fungus Drechslera australiensis gave holadysenterine as the main herbicidal constituent against this weed of wheat. Leaf disc bioassay showed that herbicidal activity of holadysenterine was comparable to that of synthetic herbicide 2,4-D. This is the first report of this herbicidal compound from the genus Drechslera.
