T-2 toxin production by Fusarium acuminatum isolated from oats and barley.

AUTOR(ES)
RESUMO

Oats grain from South Africa was frequently found to be infested by toxic strains of Fusarium acuminatum, as was one barley sample. All 11 toxic strains tested produced T-2 toxin (0.8 to 2,600 mg/kg), and 6 of 11 strains produced diacetoxyscirpenol (0.6 to 8.4 mg/kg). This is the first record of T-2 toxin-producing Fusarium isolates from Africa and of the production of large amounts of T-2 toxin at relatively high (25 degrees C) temperatures.
