Research led by Cornell University and funded by Northern New York Agricultural Development Program is evaluating how biocontrol nematodes applied to reduce the impact of alfalfa snout beetle can combat corn rootworm. Across 85 fields on farms in Northern New York where biocontrol nematodes have been applied to reduce snout beetle populations, research has shown that the biocontrol nematodes persist in fields after rotation to corn. In trials since 2014 at the Musgrave Research Farm, biocontrol nematodes have reduced corn rootwom feeding damage as well or better than the best Bt toxin-containing corn variety. The biocontrol nematode is also being tested in field trials in New Mexico, Ohio, and Michigan.
