<ol><li> Evaluate strobulurins, trazoles, and traditional fungicides and conbinations of fungicides for their activity against Aspergillus (A.) flavus and their effect on aflatoxin produciton.</li><li>Determine optimum rate and timing of application of Afla-Guard.</li><li>Fungicide and Afla Guard interactions NOTE: All trials will be carried to yield and concentrations of aflatoxin will be determined from each plot.</li> <ol>In addition, laboratory isolations will be made to determine the ratio of toxigenic and non-toxigenic Aspergillus flavus present from each plot and the potential interaction with fungicide products.
<p>Evaluate the efficacy of Afla-Guard in at least five Mississippi Delta field sites, at three application rates and several application times, on side-by-side irrigated and non-irrigated corn. In laboratory and field trials the effect of fungicides on Aspergillus (A.) flavus will be measured.</p>
