If it isn?t one thing, it is another. In a year where we must get every bushel squeezed from our fields, we don?t have any room for error. One cornbelt entomologist is seeing signs and conditions that point to some armyworm infestations possibly springing up in midwestern fields.
Nick Seiter is an entomologist at the University of Illinois. He talks about the armyworms and their migration into the Midwest from the south, which begins in late April, and comes to a head about now.
What makes them unique is how they attack corn crops. Their larvae start from the edges and work inwardly. It will appear as rough, almost raggedy, edges.
Also, those who are producing wheat may be seeing these pests in their fields as well. As cover crops or other grassy weeds die, the wheat plants become their primary target.
Wheat can withstand an attack of armyworm a little easier than corn can. They can take a little more defoliation. However, if you start to see the signs in your fields, don?t hesitate? investigate. Armyworm is also just one species in a whole family of pests.
Remember that armyworms can become even more problematic in the late summer and early fall. Be ready to adjust your attack plan if necessary.
