Crop protection machines from individual drones or unmanned aerial vehicles (UAVs) are already widespread across the world especially in south east Asia, now more and more countries in the world are allowing drones to be used for limited and specific trials and, in some cases, commercial operations in agriculture, horticulture, viticulture and forestry. Spraying for disease, weed and pest control, spreading micro-granular pesticides and fertilizers – and even beneficial insects – as well as planting new forests are among the diverse uses now being found for drones.
For the most part, Chemical spraying drones make sense where they can replace labour-intensive and potentially harmful use of backpack sprayers and similar equipment, in these situations where terrain and/or ground conditions rule out the use of conventional or even specialist vehicles.
