Thorvald

Norwegian autonomous UV-C robot that replaces fungicide sprays for powdery mildew control — working at night in UK tabletop strawberries (used by 13 leading growers, around 20–30% of the national tabletop crop) and California vineyards, where over 150 Thorvald 3.0 units ran the 2025 season. Delivered as a service rather than a machine sale, with a vineyard-specific model launched for 2026.

Available in: United Kingdom · United States

At a glance

Best for

Larger tabletop strawberry and wine-grape operations in Saga's service regions (UK, US) wanting to cut fungicide programmes without buying or operating robots themselves.

Avoid if

You farm outside Saga's current service footprint (UK strawberries, California vineyards, Norway) or want to own and run the machine yourself — Thorvald is offered as an operated service.

Not suitable for

Arable, vegetable and orchard crops; smallholdings outside the service regions; growers needing a purchasable machine with published pricing.
