Excerpt from Evaluation of Four Inert Dusts for the Protection of Shelled Corn in Georgia From Insect Attack Commercial grades on corn samples were lowered by treatment with the inert dusts. Test weight was lowered an average of pounds per bushel on corn treated with diatomaceous earth and pounds per bushel on corn treated with silica aerogel. The test weight of the untreated and malathion-treated corn was almost unchanged. Dust treatments reduced the loading capacity of the grain conveyor to one-half its capacity for untreated or malathion-treated shelled corn. Dust-treated corn was packed and very difficult to probe for samples. The overall moisture content of the corn decreased slightly during the year's storage. Residues on malathion-treated corn averaged p.p.m. Immediately after treatment and decreased to p.p.m. By the end of the year. All treatments reduced the initial insect infestation to a very low level in the corn. The number of insects in the untreated check corn, however, continued to increase, and by the second month of storage, this corn was weevily according to official Grain Standards of the United States. Sg-68 and malathion were the most effective in keeping insect populations from develop ing in the corn. Perma-guard, Kenite, and cab-o-sil lost much of their effectiveness after 9 months' of storage, as evidenced by increases in numbers of live insects, development of insect progeny, and insect-damaged kernels. One bin of corn treated with cab-o-sil was weevily after 1 year's storage. Perma-guard provided the shortest residual protection. One bin became weevily at 11 months and two more bins at 12 months.
