Abstract

In pesticide applications, small droplets are desired for better coverage and uniform distribution. Yet, small droplets have a problem: Drift, the movement of droplets off-target. LOW DRIFT NOZZLE produces fewer drift-prone droplets, < 100 mm, compared to standard hydraulic nozzles. In pesticide applications, standard hydraulic nozzles, hollow cone and FLAT FAN NOZZLEs are generally used by farmers. These nozzles have broad droplet spectrum and high proportion drift-prone droplets. Sample of drifted droplets and measurements in field conditions are expensive and can be time-consuming. However, models can be applied to predict drift without field measurement. In this study, model and field measurement of percentage pesticide drift were compared using different hydraulic nozzles, D4-45, F 11006 and LD 11003 by gas chromatography equipped with a nitrogen-phosphorus detector. In the result of this study, for all nozzles, values up to 2 m and 3 m showed that there were statistically different according to GERMAN MODEL and DUTCH MODEL, respectively. In the result of this study, percentage drift at 5 m compared to 1 m distance decreased approximately 15 folds in LD 11003, 12 in F 11006 and 10 folds in HC D4-45 nozzles in actual application and 5 folds in German and 9 folds in DUTCH MODELs.
