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.
Hearken® biological insecticide is a virus that targets Heliothine 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.
