Biological Control of Codling Moth in Fruit Tree Orchards

Developed from a unique strain of codling moth granulovirus, this biological insecticide provides highly targeted control of codling moth (Cydia pomonella) in apple and tree fruit orchards. By infecting newly hatched larvae before they enter the fruit, it helps protect yield and fruit quality while reducing pest populations over time. Compatible with Integrated Pest Management (IPM) and mating disruption programs, it preserves beneficial insects, leaves no residues and provides growers with an effective resistance management tool for sustainable orchard production.

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.

Quantity

167- 250 mL/ha

Frequency

Apply according to codling moth monitoring and egg hatch predictions. Multiple applications may be required during periods of sustained pressure.

Best Time to Apply

Begin applications at egg hatch so newly emerged larvae encounter the virus before entering the fruit.

Application Method

Apply as a foliar spray with thorough coverage of fruit and foliage. Shake well before use and maintain good spray coverage throughout the canopy.

Tank Mix / Adjuvants

Compatible with many insecticides, herbicides and fertilizers. Confirm fungicide compatibility before mixing.

Pre-Harvest / Residues

No residue concerns. Suitable for use throughout the season, including late-season applications.

Key Product Benefits

Highly Targeted Control

Specifically targets codling moth larvae without impacting beneficial insects, pollinators or natural enemies.

Protects Fruit Quality

Stops larval feeding before fruit penetration, reducing crop damage and protecting marketable yield.

Supports Resistance Management

Contains a unique CpGV-CP4 lineage that provides an important tool for resistance management programs.

Residue-Free Solution

Leaves no measurable residues, supporting late-season use and meeting export market requirements.

Organic and Reduced Risk

Certified organic and classified as a reduced-risk product, supporting safer pest control for human health and the environment.

IPM and Mating Disruption Compatible

Works alongside mating disruption programs and biological control strategies to strengthen orchard-wide pest management.

Target Pest Information

Codling Moth

(Cydia pomonella)

Codling moth is one of the most economically important pests of apples and other pome fruits. Newly hatched larvae tunnel directly into fruit, causing internal feeding damage, reduced fruit quality and significant yield losses. Multiple generations can occur throughout the growing season, while resistance to several conventional insecticide groups has increased the need for alternative control strategies. Early intervention and the use of biological solutions with unique modes of action are essential for effective long-term population suppression and resistance management.
