The result to aim for
Luc Tesnière, farmer in Calvados, weeds his onions with an Ecorobotix Ara sprayer that distinguishes cultivation and adventitious and treats only weeds.
What was done
On July 14, 2026, Luc Tesnière's testimony (SCEA Tesnière, Ernes, 400 hectares, including 25 onions and ecalotes) was reported. The list of authorised herbicides ononion has been widely reduced and the treatments in full worn the bulbs. The Ara sprayer, designed by the Swiss company Ecorobotix, has 156 nozzles driven by six cameras and an AI that differentiates adventitious culture and deals with 6 cm squares. After a rental for the 2024 season, three farms (SCEA Tesnière, SCEA Haghebaert, EARL Hardy) bought in condominium the following year for 125,000 euros, with local aid of 30,000 euros. The tool also serves on carrots and meadows. The farmer sees wider and more homogenous onions; the title of the article references to weeding costs distributed by oven.
