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
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.
Ground Rig: Minimum of 40 gallons per acre
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.
