Cereal Leaf Beetle Update

During the CORN conference call this morning it was shared by educators across the state that thousands of acres are being sprayed for cereal leaf beetle(CLB) in a near frenzy. I guess a front page business section in the Columbus Dispatch got the pesticide sales folks all worked up to make some money. I have been in fields here that have CLB but NOT at economic threshold levels. Remember that the flag leaf is where we want to focus our attention.

If beetles are present, evaluate the percent of flag leaf damage and the number and size of the larvae feeding. Check the following link that I sent to many of you on the CORN newsletter group last week.
