Within-band spray distribution of nozzles used for herbaceous plant control
Abstract. Described are the spray patterns of nozzles setup for banded herbaceous plant control treatments. Spraying Systems Company nozzles. were tested, but similar nozzles are available from other manufacturers. Desirable traits were considered to be as follows: an even distribution pattern, low volume, low height, large droplets, and a single nozzle or short boom. The nozzles that best matched these traits are as follows: a TW flooding tip, a TF2 "Turbo" flooding tip, and 3 each XR8002 flat-fan tips spaced 19 in. apart---all best at 15 psi. Also, 2 each 9502E (even) flat-fan tips on a 2O-in. boom attached to a wand on a spraygun had a fairly even distribution (C.V.=O.38-0.40) and was superior to a regular wand for applicator control.
