Sprayer drone demonstration

Flown by Alex Helms, Southeast Purdue Agriculture Center

This DJI Agras spray drone is designed for precision variable rate application of liquid pesticides, fertilizers, and herbicides as well as an attachment to spread dry treatments. The spraying system automatically adjusts its speed according to the flight for an even application. It is 40 to 60 times faster than manual spraying, bringing a new level of efficiency to agricultural operations.

Purdue Extension and the Purdue Agriculture Center (PACs) jointly purchased this intelligent spraying system in 2019.
