As always, moth trapping data for the season can be found on the quick links menu (http://www.utcrops.com/BlogStuff/2017MothTrappingData.pdf). We are now catching a few more corn earworm (bollworm) moths, but nothing too startling. However, it is clear that the second generation moth flight for southwestern corn borer is underway, and we will catch even more moths next week. Keep in mind that there is a lot of variation among locations. It can be a waste of money to treat for southwestern corn borers based on trap catches that are not near your fields. You should be running a few of your own moth traps near fields of non-Bt corn, especially in areas where non-Bt corn was grown the previous year.

Treatment recommendations are available in the previously written articles linked below. The second article references Belt SC as an insecticide option, but the registration of this product was recently cancelled.
