Abstract:The effect of the biological activity of the kernel on the rate of malathion degradation was determined during 9 months of storage. The migration of malathion residue to the endosperm and embryo of sterilized sorghum grains was greatest during the 1st month of storage; however. the amounts recovered during that time accounted for only 41.4% of the remaining total malathion residue. After 3 months' storage, the total residue gradually decreased. until 34.3% of the initial total dc, posit remained at the end of 9 months. At all time intervals during the 9 months' storage, more malathion residue was detected on, and in, the sterilized sorghum kernels than on the live, viable kernels, but the patterns of residue decline were similar. Only 14% of the initial malathion deposit remained on the viable sorghum after 9 months' storage. These findings indicated that during a normal storage period enzymes contribute to the breakdown of malathion applied to sorghum grains as an insect protectant.
