This experiment was conducted to determine the effects of optimal types and levels of chemicals in order to control growth of fungi and aflatoxin production on moist corn (25% moisture content) stored for 8 weeks.  This experiment was used 2 types of chemicals that were propionic acid at levels 0.2, 0.4, 0.6, 0.8, and 1.0 percent (w/w) and sodium chloride at levels of 2, 4, 6, and 8 percent (w/w).

            At the end of the experiment showed that propionic acid at levels of 0.2 and 0.4 percent (w/w) was able to control aflatoxin production for 8 weeks but they could not control fungal growth.  Propionic acid at level of 0.6, 0.8, and 1.0 percent w/w was able to control aflatoxin production and growth of fungi for 8weeks.  Sodium chloride at levels of 2, 4, 6, and 8 percent w/w controlled aflatoxin production for 8 weeks but efficiency of fungal control was not significant.
