During the past three summers, corn rootworm insecticides and YieldGard Rootworm® corn were evaluated in side-by-side trials at several locations across the state. These field trials measured performance in protecting corn roots under a wide range of environmental conditions. Performance was then measured as root injury, product consistency, plant lodging, and grain yield. The same corn hybrid (non-rootworm) was planted for all of the insecticide treatments at each location and year, plus a YieldGard RW® hybrid that contained the cry protein for corn rootworm control.
