Clean, Treat Grain Bins Now to Save Time, Trouble Later

Changes in products are something to stay abreast of.

This is a busy time of year for the nation´s farmers, but getting one chore done now - cleaning and treating grain bins - will pay off later, says Kansas State University entomologist Phil Sloderbeck.

"Now is a good time to clean and treat grain storage areas and to decide if grain going into storage will need to be treated with a protectant insecticide," says Sloderbeck, who is the state leader in entomology.

Help for producers in making those decisions is available at county and district K-State Research and Extension offices and online, Sloderbeck said. Growers can refer to the publication "Stored Grain Insects, Part III: Structural sprays, pest strips, protectants and surface sprays."

The publication is on the Web in K-State Research and Extension´s "library" at It´s also on the entomology department´s Web site at

"Over the past few years, there have been many changes in products that are labeled to treat grain and grain storage areas," Sloderbeck says. "One new product for this season is Diacon-D, which contains the insect growth regulator methoprene. This product is a dry formulation, containing the same active ingredient as liquid formulation Diacon II."
