Trait and insecticide efficacy against Bt-susceptible and Bt-resistant western corn rootworm (Diabrotica virgifera virgifera) populations: Implications for managing resistance, populations and crop loss

The advent of western corn rootworm resistance to Bt-RW traits has created management uncertainty.  Amidst the diversity of "best" management practices aimed at crop protection, its important to consider management that management tactics have implications for resistance and population management as well as crop protection.  This presentation will examine the array of management tactics. alone and in combination. in Bt-RW susceptible and Bt-RW resistance situations based on MN on-farm research spanning 5 years and 16 field situations.
