Hearken™ biological insecticide

  • Biological Insecticide

Natural Control of Corn Earworm

Hearken™ biological insecticide is a virus that targets Helicorverpa species, such as corn earmworm, tobacco budworm and the Old World bollworm. Used as a foliar application, Hearken is safe for beneficial and non-target organisms and complements traditional chemistries to easily fit within integrated pest management programs.

Benefits

Controls Helicorverpa Species Across Generations

Helicorverpa Species lifecycle illustration

Hearken™ biological insecticide is a virus that infects larvae through ingestion. On death, larvae liquify and release millions of virus particles to infect other larvae.

Larvae with sub-lethal infections – typically larger larvae – transmit infection to their offspring hence reducing their biological fitness to continue the life cycle for the next insect generations.

Safe for Non-targeted Organisms

Grain sorghum

The virus that infects Helicorverpa species does not impact beneficial or non-target organisms, meaning you can apply with confidence.
