Equipment used: JD 5220 tractor traveling 4.8 mph (gear C1, 1400 rpm) with a pull type Top Air Sprayer equipped with a hydraulic centrifugal sprayer pump and a Raven 440 automatic carrier control unit. Turbo TeeJet 11003 nozzles were used, spaced 15 inches apart with a total boom length of 30 feet. 10 psi was used. Water applied at 20 gals/A (187 L/Ha) was used as the carrier. Weather conditions at start were 61 degrees F (16.1 degrees C), 64% relative humidity, 10 minute wind velocity of 8 mph from NNE. Weather conditions at the end were 70 degrees F (21.1 degrees C), 39% relative humidity, 10 minute wind velocity of 12 mph from NNE. Because of the wind conditions, a lower boom pressure was used to create larger droplet size and reduce drift.
