Powdery mildew calls for a long series of treatments every season, organic vineyards
included. We are developing a UV-C module to be mounted on the rover which, at night,
exposes leaves and fruit to brief doses of ultraviolet light as it travels the row.
Vineyard trials carried out by international research show that, applied in darkness,
this light suppresses powdery mildew without affecting vine growth or yield, and without
leaving anything on the fruit. It is a concrete route to using fewer plant protection
products, with a treatment carried out in the same hours of darkness in which the rover
is designed to work.
