In Zanzibar, Tanzania, Anti-Malaria Drones deployed UAVs to spray Aquatain AMF, a natural mosquito larvae repellent agent on rice paddy farms
The drones used were DJI Agras MG-1S, modified by DJI to handle heavier and more viscous payloads. The flight controller software was rewritten and the hardware was modified to account for the new agent. After a month, a 90% reduction in mosquito larvae was reported
Drones can spray fields 10% to 50% faster than traditional methods while being cheaper than manual aircraft. Training farmers to use and operate the drones was also easy, since it took 2 hours or less
