Protecting Your Feed Supply from Bt-resistant Corn Rootworm
Corn rootworm is a serious pest of continuous corn. For 16 years, producers growing corn-on-corn have relied on hybrids with rootworm Bt traits (Bt-RW), sometimes called “below-ground protection”, to minimize crop damage. Since 2019, populations of corn rootworm with resistance to Bt-RW were identified in Ontario. Dairy farmers need to be proactive about how they grow corn going forward to protect their feed supply and mitigate rootworm resistance. Christine will discuss agronomy strategies to keep corn in the ration.
