Objectives:
- develop a custom-designed, five-port, air-assist sprayer to improve spray penetration into dense nursery canopies while minimizing off-target loss
- determine optimal sprayer characteristics such as air velocity and nozzle height to provide sufficient spray deposition for effective pest control within dense canopies.
