You will be glad to see a story from the German vineyard test project: We need 1800L per hectare by hand; the spraying drone only needs around 100 L.
Fast, quiet, cheap, and extremely environmentally friendly: the first trial project in Germany on the use of drones for crop protection has convinced everyone involved. The German winegrowers’ cooperative Roter Bur in Glottertal (Württemberg) was also involved. Those responsible describe their experiences with the use in the vineyard.
