Spray drones prove effective for crabgrass management in turf

Until now, not much was known about the influence that nozzle type and application volume have on weed control efficacy with remotely piloted aerial application systems (RPAASs). However, new research shows that RPAAS applications using low-drift nozzles at low spray volumes (1.0–1.5 gallons/acre) can achieve weed control levels comparable to ground sprayer applications at 10 gallons/acre in turf.
