Below is an excerpt from the 2020 UGA Corn Production Guide (page 79): The key to storing grains and other commodities on the farm is to make storage conditions unfavorable for the survival of stored grain insects and molds. Growers who will be storing for more than 6 months should strongly consider application of a grain protectant. Apply an approved grain protectant directly to the moving grain stream at the bottom of the bucket elevator or auger so the material has an opportunity to contact as many kernels as possible as the grain is moved.

Insecticides labelled for direct application to grain as a grain protectant

Pirimiphos-methyl Actellic 5E 8.6-11.5 fl oz (corn) 8.6-11.5 fl oz (grain sorghum) 1B Labeled for use on shelled corn, popcorn and grain sorghum only. DO NOT use if grain has been previously treated with Actellic or if Actellic will be used as a topdress treatment.
Deltamethrin Centynal EC 8.5 fl oz (corn) 9.1 fl oz (wheat) 4.9 fl oz (oats) 8.5 fl oz (grain sorghum) 8.5 fl oz (rye) 3A Labeled for use on barley, corn, oats, popcorn, rice rye, grain sorghum, and wheat.

Will not control weevils. Diacon IGR is an insectgrowth regulator that interferes with the development of insects; it will not kill adult insects. Treat existing insect populations with an adulticide before or at the same time as applying Diacon IGR. Apply only once to grain of known treatment history. Use highest rates for maximum residual. Lowest rate provides shorter residual.
S-methoprene Diacon-D IGR 8-10 lb 7A Labeled for use on cereal grains, corn, sunflower, canola, legumes, popcorn, wheat, spices, grain sorghum, rice, cocoa, peanuts, oats and millet. Will not control weevils. Diacon-D IGR is an insect-growth regulator that interferes with the development of insects. It will not kill adult insects. Treat existing insect populations with adulticide before or at the same time as applying Diacon-D IGR. Apply only once to grain of known treatment history

Diatomaceous earth Dryacide 100 1-2 lb/ton Thoroughly mix with grain. For use on grains, soybeans, peanuts, popcorn, and others (see label). Diatomaceous earth products are less effective when used on grain with increased moisture content and under humid conditions; diatomaceous earth is known to decrease test weight and grain flowability.
