Abstract

In this episode of the “Tip of the Iceberg” podcast, Dr. Pam Marrone, co-founder of Invasive Species Corp., explores the evolving role of biologicals, biopesticides, and biocontrols in agriculture. She clarifies key distinctions, explaining that biocontrols use natural predators, while biopesticides rely on microorganisms. Contrary to common belief, 70% of biologicals are used by conventional farmers, not just organic growers.

Marrone highlights the benefits of biologicals, including lower residue levels, shorter reentry intervals, and improved soil health and biodiversity. Integrated with chemical programs, they enhance pest control and crop quality. The biologicals market, currently 10% of agricultural inputs, is projected to rival chemicals by 2040.

She encourages growers to revisit biologicals, as advancements have significantly improved efficacy. “If you tried biologicals five years ago, try them again,” she advises, emphasizing the rapid innovation in biological pest management.
