Another Successful Farming webinar took place Wednesday. University of Minnesota Extension Entomologist Ken Ostlie kicked it off by discussing different management options and their varying solutions. “If we’re talking about soils and insecticides, they aren’t going to give us a good kill so they’re not good at managing resistance. They are good at reducing lodging and maintain harvestability. In contrast with BT corn, you’re getting very good protection of the root system and in a susceptible situation it could kill a population. But with varying degrees of resistance out there on the landscape, it’s hard to predict what kind of kill you’re going to get.” Ostlie says crop rotation is just one tool to help improve soil health. “Other aspects of corn production include hybrids themselves in terms of their root architecture and ability to tolerate feeding when they’re planted.”
