End Date: Jul 31, 2013
Collections of Aspergillus flavus from agricultural environments in Arizona and Texas will be screened for sensitivity to agrichemicals. Relationships between chemical sensitivity and chemical exposure will be assessed. Genetic relationships among sensitive and resistant fungi will be assessed and barriers to gene flow among resistant and sensitive isolates evaluated. Competitiveness of resistant and sensitive fungi will be compared and attempts will be made to select atoxigenic strains with improved resistance to agrichemicals as elite biocontrol strains.
