The best way to minimize the risk of devastating crop damage is to help maximize control of high-pressure corn rootworm* below ground while protecting against above-ground pests.
Root damage is primarily caused by corn rootworm larval feeding. Every root node nibbled by larvae can result in a yield loss of approximately 15%.¹ In addition, root lodging can impede harvesting, further reducing grain yield by 15%–34%.²
