Abstract

In a stationary sprayer in a laboratory, wear was not detected in nozzles delivering α,α,α-trifluro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) in 4.3 to 6.9 gpa (assuming 4 mph at 30 psi) after 60 hr of use. In contrast, there was 1.7 to 2.0% increase in discharge volume during the first 5 to 10 hr from nozzles delivering 12.9 to 26.6 gpa. Wear was attributed to the greater amount of liquid discharged through the larger nozzles. Average wear in stainless steel nozzles was 1.7% as compared with 2.5 and 2.6% in brass and aluminum nozzles, respectively, delivering 4.3 to 26.0 gpa over a 60-hr period, while volume decreased 4.1% in nylon nozzles. Although trifluralin concentrations in the field were lower when the herbicide was applied in 2.7 or 5.4 gal of carrier/A, as compared to nozzles discharging 8.0 to 31.0 gpa, control of smooth pigweed (Amaranthus hybridus L.) was 95% or higher with all carrier rates 6 months following application.
