French Winegrowers Seek Drone Approval After Floods Halt Vineyard Work

2026-03-23

Heavy rains leave fields inaccessible, prompting urgent calls for expanded drone spraying to protect crops from disease and further losses.

Vineyards in the Aude region of southern France are facing a new challenge after three years of severe drought. This winter and early spring, heavy rainfall has flooded many parcels, with water levels reaching up to 80 centimeters in some areas. Local weather data shows that nearly 800 millimeters of rain have fallen in recent months, compared to just 200 millimeters over the previous three years combined.

The saturated ground has made it impossible for winegrowers to access their fields with tractors. In one case, a grower resorted to pruning his vines from a kayak. Damien Onorré, president of the Aude winegrowers’ union, explained that planned plantings have been delayed or canceled, and pruning work—now often done by machine—has fallen behind schedule. In some locations, the soil is so waterlogged that growers do not expect to enter their fields before June. “After losing three harvests to drought, we cannot afford to lose a fourth because of rain,” Onorré said.

The timing is especially critical as spring brings the first appearance of vine buds in Languedoc and marks the start of treatments against mildew and other diseases. With traditional machinery unable to reach flooded parcels, local winegrowers have requested permission to use drones for spraying treatments. This request covers both organic and conventional vineyards. Normally, drone spraying is authorized on a parcel-by-parcel basis, but growers argue that this approach is unworkable given the scale of the flooding. They are seeking broader permissions at the municipal or even departmental level.

Winegrowers in neighboring Hérault have joined the call for expanded drone use. Ludovic Roux, president of the Aude Chamber of Agriculture, said this would be a first for the region. He noted that drones can target water droplets on vines with precision, making them well-suited for these conditions.

Roux also pointed out that these extreme weather swings—from prolonged droughts to intense rainfall—are clear signs of ongoing climate change. He stressed the need for urgent action to manage water resources more effectively. Immediate solutions include drilling wells, while medium-term measures could involve building hillside reservoirs. In the longer term, extending the Rhône River pipeline toward Aude and Pyrénées-Orientales is being considered.

For now, winegrowers are waiting for authorities to respond to their requests as they try to protect this year’s crop from disease and further losses. The situation highlights how climate volatility is forcing rapid adaptation in one of France’s most important wine regions.
