21 What role should spray nozzles play besides volume? Spray nozzles directly affect: spray droplet size spray drift potential uniformity and coverage Which impacts: weed control economics environmental quality
22 Droplet size, drift, and coverage (Droplets <200 µm are the most prone to drift) 13.5 gpa Spray droplet diameter (µm) Spray droplet category Example F Dry fog <145 Very fine Wet fog M Fine Mist/drizzle Medium Very fine rain Coarse Fine rain C Very coarse Light rain >500 Extremely coarse Medium rain Heavy rain VC XC
23 Spray nozzle designs available: Extended Range design (XR) <20% 200 µm; most are F-M Chamber design (Turbo) <6% 200 µm; most are M-VC Venturi II design (Air Induction) <3% 200 µm; most are VC-XC Venturi I design (Turbo Induction) <1% 200 µm; XC
24 Can we use drift-reducing nozzles that create larger droplets to help reduce the risk of spray drift and still get acceptable weed control, particularly with burn-down herbicides like Rely or Treevix?
