Abstract
Fusarium isolates from specific diseased sorghum plants and rain-soaked wheat and wheat flour associated with human mycotoxicosis in India have been screened for their toxigenic potential. Of the 322 isolates screened, 11 isolates were found to produce deoxynivalenol in concentrations ranging from 0.01 to 186 micrograms g-1. The occurrence of deoxynivalenol-producing fusaria in a nontemperate region and deoxynivalenol production in low concentrations by Fusarium moniliforme are reported for the first time.
