Abstract
The purpose of this study was to evaluate the effectiveness of two Bt rootworm traits (Cry3Bb1 and Cry34/35Ab1) with and without an RNA interference trait (DvSnf7) for management of corn rootworm (CRW) larvae. The two CRW trait packages evaluated in this study were a pyramid Cry3Bb1 and Cry34/35Ab1 (SmartStax®), and a pyramid of Cry3Bb1, Cry34/35Ab1 and DvSnf7 (SmartStax PRO®). Both of the CRW trait packages were replicated twice, using two different hybrids with each trait package. Additionally, two non-CRW Bt hybrids were included in this study as untreated checks.
