Abstract
A stem rot, similar to that caused by Sclerotinia minor on sunflower (Helianthus annuus), was observed on the weed, Bathurst Burr (Xanthium spinosum), in a sunflower field trial at Numurkah, in north-central Victoria. It was confirmed that the fungus causing the stem rot on the Bathurst Burr was S. minor. This is the first record of this fungus affecting X. spinosum.
