Heligen is a highly effective natural baculovirus-based biological control.

Used either as a classical insecticide to target economic populations of Helicoverpa, or applied when crops first become attractive to caterpillars, Heligen introduces a baculovirus that specifically targets Helicoverpa.

Depending on the crop, Heligen generally works best when used as part of a grower’s pest control regime. It reduces the overall costs of pest control by enhancing the natural defence mechanisms against Helicoverpa.

The baculovirus multiplies and spreads through the Helicoverpa population—generally lasting for the duration of the crop. Heligen continuously suppresses the pest without causing flare-ups in other insect populations, and provides substantial reductions in damage caused by sub-threshold damage from Helicoverpa larvae.

The product contains the nuclear polyhedrosis virus (NPV) of Helicoverpa armigera and Helicoverpa zea.

The Heligen formulation has a virus concentration 2.5x greater than other commercially available NPV products. For the farmer, this means lower use rates and reduced packaging and storage requirements.

Key points on performance

  • Excellent spray coverage critical to achieve good results
  • Larvae must ingest the virus to become infected
  • Apply during warm conditions (77-95°F) when larvae are actively feeding
  • Peak control at 4 to 9 days after application (faster in warm conditions)
  • Provides between 60 to 90% control depending on coverage, environmental conditions and size of larvae
