Corn Rootworms – 2012

Your Farm Business

August 17, 2012
By Tina LeBrun and Wayne Schoper - South Central College , The Journal

Corn rootworms have been around as long as corn has been grown in our area. They can cause severe damage to corn fields by destroying roots and thereby inhibit nutrient uptake and standibility of the corn plant. We tend to see significant numbers of corn rootworms show up when we plant corn-on-corn for a number of years. Planting corn year after year has become very popular in recent years because of high prices and excellent yields. Corn rootworms have developed resistance to many control tactics over the last 50 years including crop rotation and soil and foliar applied insecticides.
