Recent digital technology improvements have spawned the ability to scan entire fields quickly and inexpensively with drone flights, then provide maps identifying specific weeds and their locations — all in about 12 hours.

There’s new smart spray technology from precision ag startup Sentera that could lower herbicide usage by up to 70%. It’s called Aerial WeedScout. It uses aerial imaging from a drone and artificial intelligence to detect weeds. Then it creates prescriptions within 24 hours that can be executed through any precision sprayer. Sentera CTO Eric Taipale explains what separates Aerial WeedScout from other precision spraying options on the market.
