An agronomist is seeing the threat of a 2021 corn rootworm problem.
Eric Birschbach operates Ag Site Crop Consulting in Verona, Wisconsin. He tells Brownfield his customers in Dane, Iowa, Lafayette counties experienced some strong winds before corn reached the tasseling stage. “Especially in southwest Wisconsin, it blew a lot of corn down. Looking at those corn plants, they were missing some of their roots so we’d have about six, six-and-a-half-foot tall corn, but the root mass that would be maybe as big as your fist, and I don’t have a very big fist, so that was a problem.”
He says by then, the root mass should have been much bigger. Birschbach says a lot of that corn goosenecked up after being blown down, but it sounds the alarm for what might be coming.
