WHAT TO EXPECT AFTER APPLICATION
Up to 3 days after application
Infected larvae continue to feed but become lethargic and move upward on the crop – thus, exposed to heat and more vulnerable to predators.
4-6 days after application
Feeding gradually stops and, often, sick are found on top of crops or hanging under the plant's canopy, being cannibalized by other CEW larvae. Larval skin bursts open, releasing billions of viral particles onto the crop. These particles are effectively dispersed by wind, rain, and many arthropods, including predators that feed on the dead larvae cadavers extending season-long control of resistant soybean podworms, corn earworms, and bollworms alike.
Do not use Heligen® as a curative treatment past the 4th Instar (medium-large CEW). In this situation, alternative control methods should be considered.
