Autonomous farming technologies promoted by agricultural tech firms could significantly reshape the workforce in Northern California’s wine country, where laborers have long played a central role in vineyard and crop management.
The equipment was featured June 30 during a UC ANR Innovate event at the Hopland Research and Extension Center, where eight agricultural startups demonstrated their latest tools and systems.
UC ANR Innovate serves as the innovation arm of the University of California’s Agriculture and Natural Resources division.
With 5,358 acres of rugged terrain in the Northern California Coast Range and a wide range of elevations, the Hopland Research Center offered an ideal testing ground for the next generation of farm technology.
“Field days are where the abstract work of agricultural innovation becomes concrete. When you get a startup, a farmer and a researcher in the same field looking at the same piece of equipment, the questions get sharper and the feedback gets more useful,” UC ANR Innovate Director Helle Petersen said.
Saga Robotics presented Thorvald, its autonomous robot designed to help manage fungal diseases such as powdery mildew using UV-C light. The system is used on crops including strawberries and grapevines.
Agtonomy, another company at the event, highlighted software that enables farmers to carry out repetitive tasks such as mowing and weeding with autonomous, remotely operated equipment.
Lumo, a precision irrigation platform designed to deliver the right amount of water to crops, was also among the technologies on display.
Other companies at the field day included CropMind, Phytech, Verdi, Ag-Bee, and Scout.
The field day was part of UC ANR Connect, the applied innovation programming branch of UC ANR Innovate, and was run in partnership with Farmhand Ventures.
Farmhand Ventures is a venture capital firm that invests in “pre-seed and seed stage agtech companies that are enabling a just transition towards the future of work in agriculture in the US.”
While a rise in autonomous robots into vineyards can slash chemical pesticide use and eliminate safety hazards, it could lead to a widespread displacement of seasonal field workers.
In Napa Valley, the farmworker workforce is around 9000 while about 60% of farmworkers work seasonally, according to an assessment made by the Napa County’s Board of Supervisors in 2024.
