Abstract
The purpose of this study was to evaluate the effectiveness of Bt corn targeting corn rootworm and soil insecticide, either alone or in combination, for management of larval corn rootworm injury. The Bt trait packages evaluated in this study were: DeKalb Smartstax RIB, Pioneer Qrome, and Syngenta Duracade. All three of these hybrids contain two Bt traits that target corn rootworm larvae. Also evaluated was the soil-applied insecticide Aztec HC. Pioneer AcreMax (AM) was included in this study as a non-rootworm Bt check.
