Helicovex®
Advanced Baculovirus Technology
Helicovex® is a baculovirus-based biological insecticide that targets corn earworm larvae, offering growers of corn, outdoor hemp and cannabis a unique mode of action. This is especially valuable as 30 – 40% of populations show resistance to common chemistries.
Safe for beneficial insects, Helicovex® is applied during early moth flight when young larvae ingest the virus. Feeding stops quickly and mortality occurs within 5 – 7 days. Multiple applications spaced 7 – 12 days apart align with the pest’s life cycle, supporting effective population control.
Highly compatible with most crop protection products, Helicovex integrates seamlessly into IPM programs. It provides both horizontal and vertical transmission within pest populations, supporting extended suppression. With no MRL, Helicovex® can be applied right up to harvest, offering maximum flexibility for growers.

Application Guidelines
These guidelines are intended as general recommendations. Always read and follow the product label. For crop-specific advice, consult your local Andermatt representative.
50 - 200 ml/ha (adjust for fast-growing tissues or early stages)
Reapply every 6 - 8 days; for fast-growing tissues like silks, every 3 days
Target eggs or small larvae; start early and continue through larval hatching period
Good coverage of feeding plant parts; minimize run-off; use water-sensitive cards to check coverage
Compatible with most insecticides, fungicides, fertilizers (pH 5 - 8.5); add last; optional non-ionic or oil-based spreaders; avoid copper and silicone-based products
0 MRL; safe to use up to harvest
Key Product Benefits
Utilizes a naturally occurring baculovirus to specifically target and infect corn earworm larvae, providing an effective alternative where resistance to conventional chemistries is common.
Utilizes a highly selective mode of action to protect beneficial arthropods when used alone, helping preserve natural pest control and support integrated pest management (IPM) programs.
Ingested by young larvae at early moth flight, stopping feeding quickly and causing mortality within 5 - 7 days.
Multiple applications spaced 7 - 12 days apart match the pest’s generational turnover for sustained population suppression.
Compatible with most crop protection products and carries no maximum residue limit (MRL), allowing application up to harvest and providing greater flexibility in crop protection programs.
Controls corn earworm and other Helicoverpa/Heliothis species even in populations resistant to conventional insecticides, providing a reliable tool for integrated pest management.
