Here's help in diagnosing ear damage

If you've been finding some strange looking ears of corn this summer, an article by agronomist Bob Nielsen in the September 7 issue of Purdue University's Pest and Crop bulletin might help you figure out what caused the problem.

Nielsen says there have been reports of "arrested ear development" around the Midwest this year. "Circumstantial evidence in some situations links the symptoms to post-emergence applications of herbicides, fungicides, insecticides, and/or assorted additives," he writes. "In other situations, no obvious connection can be identified with post-emergence pesticide applications.

"Definitive diagnoses of the causes of arrested ear development remain to be determined," Nielsen adds. "But it may be useful to compare and contrast the various arrested ear symptoms and what they may tell us in terms of the timing of the damage."

Nielsen's article includes several full-color photos of damaged ears and explains what could have caused the damage in each case.
