We have heard from several producers in northern Illinois who were disappointed in their 2013 Western corn rootworm management. We are working on a program that will take place at the Northern Illinois Agronomy Research Center in late February 2014 with campus entomologists to address the issue and share future research initiatives.

Today we traveled to Watseka to participate in our third soil health program. Of particular interest have been the farmer panels that share their successes and challenges incorporating cover crops into their operations.
