Abstract

This past summer, we evaluated corn rootworm technologies in side-by-side experiments at four locations in Iowa (Ames, Crawfordsville, Nashua, and Sutherland). The objective was to measure the degree of root protection and standability provided by the corn rootworm Cry proteins in each of three technologies, and then to compare them to a standard soil insecticide--Aztec® 2.1G. These field trials measured performance in protecting corn roots under a wide range of environmental conditions. Performance was measured as root injury, product consistency, and plant lodging. All tests were planted on continuous corn ground that was planted late the previous year to attract egg-laying females into the plots. Plots were replicated four times for each treatment at each location, and the same hybrids were planted at all four locations.
