After the bin has been thoroughly cleaned and treated, insecticides can be applied to the grain as it goes into the storage area. Insecticides registered for application to whole grain are called grain protectants. Most labels recommend application as the grain is entering the auger for delivery to the final storage site. Refer to the accompanying table for information on applicators and calibration. Even distribution of the product during application is desirable. Protectants also give best control when the grain moisture is low. To make enough spray to treat 1,000 bushels of grain, use one of the recommended chemicals in the table.
