Abstract
Fusarium poae (Peck) Wollenw. NRRL 3287, F. nivale (Fr.) Ces. NRRL 3289, and F. moniliforme Sheldon NRRL 3197, each grown on cracked corn (13 days at 28 degrees C), produced refusal factors in pig bioassays. Substantial quantities of trichothecenes were detected in the refused corn: T-2 toxin (30 micrograms/g) was detected in corn fermented with the F. poae strain; the level of vomitoxin (1 microgram/g) in corn cultured with F. nivale did not account for the 48% refusal response in the pigs tested. The F. moniliforme concomitantly produced T-2 toxin (33 micrograms/g) and vomitoxin (1.5 micrograms/g). This strain's taxonomic position was reexamined, and it is shown to be a cultural variant of the species F. tricinctum (Cda.) Sacc.
