Technical Abstract: Contamination of preharvest corn by Aspergillus flavus and production of aflatoxins in contaminated grain continues to be a concern due to the health and economic losses incurred by susceptible corn lines. A number of compounds occur in corn kernels for which no studies have been done on their ability to affect A. flavus. The objective of the work described here was to evaluate selected metabolites in this group for their effect on growth and aflatoxin B1 (AFT B1) production by Aspergillus flavus NRRL 3357, a line which is relatively resistant to inhibitors. The results would indicate if known compounds, at higher levels or greater tissue specificity, could be used to control the level of aflatoxin in corn. The suspended disc culture method was used in evaluating the compounds.
