Grain that is to be stored for longer than six months may need a protective application of an approved insecticide. Treatments can be applied as the grain is loaded into the bin through the use of a metering device calibrated to apply the proper amounts. After the grain is binned and leveled, a surface dressing can be applied to prevent insects from entering the grain on the surface. If infestation occurs in spite of these precautions, fumigation of the grain will be necessary. Because of the higher tolerance of mite eggs to fumigation, the concentration of gas introduced will need to be fifty percent greater than that for insect control.
Fumigants are highly toxic, and technical knowledge is required for their proper use.
A qualified, licensed pesticide applicator should be contacted to perform the fumigation. Read and follow directions and safety precautions on labels. Handle carefully and store in original labeled containers out of the reach of children, pets, and livestock. Dispose of empty containers right away, in a safe manner and place. Do not contaminate forage, streams, or ponds.
