Saga Robotics' Thorvald fleet kills vineyard mildew with night-time UV-C, no chemicals

The author spotted Saga Robotics' Thorvald robot fleet working a Paso Robles vineyard. By day it looks mundane, but at night the robots straddle vine rows at 2 mph dosing the canopy with UV-C light. Darkness is the point: sunlight triggers mildew's DNA repair, so daytime treatment gets undone — damage inflicted at night sticks. The approach uses no chemicals and no spray rig.
