Fusarium avenaceum is described as a novel fungal pathogen of spotted knapweed (Centurea maculosa L.), a noxious range, park and pasture land pest of the Pacific Northwest, USA. Pathogenicity of this fungus was established via Koch's postulates. Two phytotoxins were isolated and characterized from the culture filtrate of this fungus, i.e., acetamido-butenolide and enniatin B. These compounds are not host selective, but do act in a synergistic manner to cause necrotic lesions on detached knapweed leaves. Both phytotoxins, acetamido-butenolide and enniatin B are active at 3.5 × 10-3M and are produced in culture in a ratio of 1:10. © 1992.
