Northern Research and Demonstration Farm
The newly labeled YieldGard® Rootworm seed corn (transgenic seed containing a Bt protein) along with two traditional granular insecticides (Force and Aztec) were evaluated for their ability to protect corn root systems from corn rootworm feeding injury. 2003 data from tests conducted at the Kanawha, Nashua, and Crawfordsville farms are presented in this report.
