Product Overview
Prevathon insect control powered by Rynaxypyr active helps optimize yield quality and quantity by controlling costly worms like armyworms, corn earworms, cotton bollworms and tobacco budworms. Leveraging an exclusive, breakthrough mode of action, Prevathon insect control helps break the resistance cycle by stopping insect feeding within minutes and delivering long-lasting residual control for up to 21 days.
Growers can make a foliar application of Prevathon insect control by ground, air or overhead sprinkler chemigation. It has a short re-entry interval of four hours, a favorable worker protection standard profile and a short PHI.
Prevathon insect control is also an excellent fit into IPM programs. It has minimal impact on many important beneficial insects when applied at labeled rates and does not flare aphids, mites or secondary pests.
