Why Use Heligen® on Field Corn?

Field Corn

Use Heligen® proactively, at first appearance of CEW eggs starting at Tasseling.

Why use Heligen®?

• Minimize Corn 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

• Reduced Input Cost

  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 10 gallons per acre

• Use Rates

  1.0 to 1.6 oz/acre.

• Pest Pressure

  At 1st appearance of CEW eggs starting at Tasseling

• 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
