| Abstract/Contents: | "The effect of four spray nozzle arrangements and injector pump frequency on uniformity along the spray path was evaluated using collector strings sprayed with fluorescent dye. Injector pump frequency and nozzle type were significant factors affecting spray deposit uniformity differences along the path (simulated crop rows). Low pump frequencies affected uniformity along the path less for cone nozzles with large wetted areas than for fan type nozzles. Injector pump frequencies of 300 rpm resulted in string fluorescence coefficient of variation (CV) values < 10. These CVs were not significantly different for CV values at pump frequencies of 1725 rpm. Uniformity of dye solution flow among adjacent nozzles (rows) was controlled by micro-tubes with injection ports near the spray nozzle at each row. There were no significant differences among mean fluorescence of four strings on different rows each injected with dye flow rates of 30, 45, or 60 mL/ min (1.0, 1.5 or 2.0 oz/ min) through 1.3 mm (0.05 in.) I.D. tubing. A WRK String Analysis System was an acceptable method for determining effects of injection sprayer parameters on application uniformity along and among rows." |
