Scottish berry producer Angus Soft Fruits is turning to cutting-edge robotics to safeguard its harvest following one of the hottest summers on record.
Its grower cooperative, Angus Growers, has partnered with Saga Robotics to deploy autonomous ‘Thorvald’ robots across farms in a bid to combat powdery mildew – a fungal disease exacerbated by Scotland’s recent hot, dry, and humid conditions.
UV light, not fungicides
Operating after sunset, Thorvald robots deliver targeted ultraviolet-C (UVC) light treatments to berry plants. The UVC disrupts the DNA of mildew spores, offering a chemical-free solution that protects fruit quality and supports sustainable farming.
“Scotland’s climate is always a challenge for growers, and this year the hot, dry days followed by humidity meant mildew became a serious threat. By using robots to deliver UV treatment, we’ve been able to manage this without relying solely on chemicals,” said Angela Porchez, general manager at Angus Growers.
Boosting yields and sustainability
Porchez said the technology has improved plant health, reduced input costs, and supported long-term sustainability goals – critical factors for growers navigating a competitive marketplace.
The partnership is part of a broader push by Angus Soft Fruits to integrate innovative agri-tech solutions across its operations. Trials are underway for drone-based pollination, tunnel cleaning, and precision logistics, especially in smaller tunnel systems.
Scaling innovation across borders
Saga Robotics, the Norwegian firm behind Thorvald, recently raised £8.4 million to expand operations in the UK and US. Thorvald currently treats around 20% of the UK’s strawberry crop, with ambitions to exceed 30% by 2026.
“Robotics, drones, and data are all becoming part of how we think about the future of berry production,” Porchez added. “We see these technologies not as replacements for people, but as tools that can help us farm more sustainably, improve forecasting, and tackle challenges that are only going to increase with climate change.”
Tech meets tradition
Amanda Brown, programme director at Scotland Food & Drink, which represents the sector, praised the initiative as a model for how innovation can secure the future of one of Scotland’s most iconic sectors.
“It’s a fantastic example of technology and tradition working together to keep our food and drink world-class, sustainable, and resilient,” she said.
