Corn Rootworm Insecticide Performance

Commercially available corn rootworm insecticides are evaluated yearly for their ability to protect corn root systems from corn rootworm feeding injury. Three newly registered products, Cruiser® and Poncho® seed treatments (at the rootworm rate) and YieldGard® Rootworm (transgenic seed containing a Bt protein), are included in the tests. 2003 data from tests conducted at the Nashua, Sutherland, and Crawfordsville farms are presented in this report
