Are ag drones really more efficient for spraying?

Just to clarify, I haven’t worked with ag drones, so I might be off here. I also don’t have farm management experience, so take my opinion with a grain of salt.

Flying the drone itself isn’t hard, but the requirements and regulations, at least in the US, are the same as crop dusters. You need both an FAA and state license for aerial spraying.
