The main problems currently exist are:
1. There are few mature and reliable plant protection agriculture spraying drone sprayer, and many manufacturers are blindly seeking big ones, ignoring the special requirements of plant protection operations.
2. Buyers buy blindly drone for agricultural spraying. As a new spraying technology, if they want to be used in agriculture, forestry and plant protection, buyers should inspect the flight control operation on the spot, learn more from the technical level, and then start.
