2024 Corn Earworm Trap Report
2024 Corn Earworm Trap Report
We are starting to see common diseases in the lower canopy of corn, as we were out scouting this past week as early planted corn has begun to tassel in Indiana.
Last week, temperatures were higher than normal, and the lack of precipitation was causing lawns to turn brown, creek and lake levels to drop, and some crops to start showing stress.
Though more of a curiosity, and infrequent, it is refreshing for us to receive calls/emails of mysterious insects “threatening” the crop.
Managing forages for hay production requires much skill.
As we move into the first days of summer, we are finished with the early season, migratory moths and caterpillars (armyworms, black cutworms) and are now into those that overwinter here. For those pheromone trapping for western bean cutworm moths, you should begin this week. This is just the beginning of an extended moth emergence and flight, with their peak activity expected 2-3 weeks from now. Those in high-risk areas, i.e., sandy soils, high moth flight and WBC history should be gearing up for field scouting of corn, even those with Bt-traits. Depending on the trait expressed by your corn hybrids, efficacy can be highly variable. Scouting of pre-tassel corn should begin once multiple moths are being captured regularly. In five different areas of a field, inspect 20 consecutive plants for egg masses which are laid on the upper surface of the top leaves of corn and/or larvae that may[Read More…]

The early onset of unusually warm temperatures across much of the Corn Belt has farmers and markets alike questioning whether the yield potential of the 2024 corn crop is being compromised.
As I write this article, in a cool, air-conditioned office, I hear others talking about how hot it is outside. I see weather app icons showing bold suns that stress how sunny and hot conditions are and will continue to be.
National Forage Week (June 16-22) is concluding this week.
