CROP SCENE INVESTIGATION – 21: What’s the pest plaguing Jim’s corn field?


Corn seed treatments have become an important management tool for farmers, helping protect against insects that feast on fledgling plants.

Often, the signs of insect damage are obvious, but the prime suspect is not always the guilty party, as Baute discovered last May when she visited Jim, a grower in Chatham-Kent. Here’s how the clues unfolded at Baute’s crop scene investigation.
