As planting season begins and corn plants begins to emerge, a very important step to take each spring is to assess the emergence of the corn plants and take note of any abnormalities, missing plants, or uneven emergence patterns.

Locally, we have been impressed with the number of black cutworm moths captured in our pheromone traps the last few weeks.

Quite a few farmers throughout the northern half of Indiana are frustrated with the slow drydown of the 2023 corn crop, especially since some grain elevators are refusing to accept grain deliveries with moistures above certain levels, e.g., 27%.

Among a number of corny oddities that appear from time to time is one that falls into the “kernel disorder” category.

Tracking the western bean cutworm moth flight wouldn’t be possible without the many pheromone trap cooperators in our network, see following “Western Bean Cutworm Pheromone Trap Report.”

Tar Spot – We continue to confirm counties with active tar spot.

It is important to continue to scout for diseases in both corn and soybeans. Recent rains have created favorable environmental conditions for the development of foliar diseases in both crops.

The biggest challenge so far this year for Indiana corn production has been the dry conditions experienced throughout the state (Figure 1).
Insecticide recommendations for controlling in-season infestations have been updated for corn, soybean and alfalfa.
