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.

Book Description
Excerpt from Evaluation in Illinois of Four Inert Dusts on Stored Shelled Corn for Protection Against Insects: A Progress Report All treatments effectively controlled the insect populations for a period of 1 year. All inert dust-treated samples contained insects during the first 3 months but relatively few thereafter. Rice weevils were predominant. All of the inert dust treatments lowered the test weight of the corn. The moisture readings were lowered due to the physical action of the dusts. The malathion-treated corn and the untreated check showed no alteration in the grade factors. The corn treated with silica aerogel was graded sample grade because of the dust, which was considered a foreign substance by the grader. Insect damage to the corn did not increase in the corn treated with inert dust or malathion. There was an increase in insect damage in two of the five untreated checks. Chemical analysis for malathion indicated that about one-fifth (approximately 2 of the malathion applied was present 1 month after treatment. This residue remained virtually constant throughout the remainder of the observation period. In laboratory bioassay tests, the malathion was superior to dust treatments in causing mortal ity, inhibiting reproduction, and reducing the number of emerging test insects. In other laboratory bioassay tests the corn treated with inert dust showed considerable repellency to the test insects.
