When treated with 3% of pure methanol (v/w) to maize kernels in traditional jute bags three days after shelling and then stored for 10 days, infected kernels by A. flavus and AF accumulation were 56% and 36 ppb respectively, while those of untreated maize were 96% and 248 ppb. When either 3% (v/w) of pure methanol or ethanol was treated to maize kernels immediately after shelling, ten days later, alcohol-treated maize showed low percentage of A. flavus infection (1 or 1.5%) and aflatoxin accumulation (<5 or 13 ppb), while untreated maize was high frequency of A. flavus infection (65%) and high level of AF accumulation (180 ppb).Read More
