Why Use Heligen® on Hemp?

The new, safe and effective option
for controlling corn earworm


Use Heligen® proactively, at first appearance of CEW of 1 small larva per 10 plants.

Why use Heligen®?

  • Minimize Hemp Damage

    Early sprays targeting small larvae and sub-threshold pest populations ensure minimal crop loss by controlling before they reach late instars, where 80% of damage occurs.

  • Reduced Input Cost

    Using Heligen® is economical

  • Great Tool

    No residue
    No known resistance ever recorded on baculovirus based insecticides

NPV Control Progression Timeline

  • 1-3 Days After Application

    Feeding may continue,but become lethargic and more exposed to the upper canopy.

  • 4-6 Days After Application

    Feeding gradually stops and, often, sick larvae hang upside down from the leaves. Their skin bursts open, releasing billions of viral particles onto the plant canopy. These particles are effectively dispersed by wind, rain, and many arthropods, including predators that feed on the dead larvae.

Preparing To Spray

Keys to maximizing results

  • Good Coverage is Key

    The A.I. in Heligen® must be ingested by larvae to be effective.

  • Volume

    Ground Rig: Minimum of 40 gallons per acre 

  • Use Rates

    2.4 oz/acre

  • Pest Pressure

    At 1st appearance of CEW of 1 small larva per 10 plants

  • Spray Solution pH

    NPV can be degraded rapidly by high (alkaline) pH.

    pH levels above 8 will damage the virus, which will reduce the level of control.

    If the spray mixture pH is above 8.0, a buffer or acidifier should be added.
