Mycotoxins produced by Fusarium oxysporum in the seeds of Brassica campestris during storage.

Three recognized mycotoxins, viz. diaxetoxyscirpenol, T-2 toxin and zearalenone, along with the fatty esters of these toxins were isolated from the flask culture extractives of Fusarium oxysporum Schlecht (IMI 273220) as also from seeds of Brassica campestris var. sarson (mustard) infected with this fungus in storage. Evaluation of biological activity and toxicity of the extractives and the effects of prolonged ingestion of the mouldy seeds by animals suggest that the infected seeds may present high toxin-risk to humans.
