Corn-on-corn acres lead to an increase of root worm issues

An agronomist says farmers should be cautious about planting corn-on-corn acres due to an increase in root worm disease.

Matt Tepley with LG Seeds tells Brownfield the corn market has incentivized farmers to plant more of the crop. “Second year corn-on-corn may not have issues, but almost all third year corn-on-corn you will have issues.”

He says there’s been an increase is disease pressure recently. “You used to be able to get two years of corn-on-corn before getting corn root worm issues.  But, with the amount of acres that have been switched, we’re starting to find out about the pressure that’s out there even in second year corn-on-corn acres.”

Tepley farmers should switch up corn varieties to help reduce the disease.
