Abstract

Center pivot field experiments for oil-based pesticide application were conducted using a new turbulent dispersion chemigation injector and a straight tube injector for oil-pesticide application through irrigation pipelines. For the straight tube injector system, oil uniformity coefficient along the lateral was 61%. The turbulent dispersion injector was set to deliver 2 oil-pesticide dispersions to the irrigation pipeline with dmax of 980 μm and 98 μm, and uniformity coefficients along the center pivot pipeline were 73% and 98%, respectively. Injector drop-size models were used to calculate an oil drop size distribution for the straight tube and turbulent injector trials. The drop-size distributions and other parameters were input into a pipeline transport model for nonsoluble chemicals in irrigation pipelines, and the model calculated oil concentration vs. distance curves for each trial. The root mean square deviation error between experimental and simulated concentration curves were 40%, 28%, and 3% for the straight tube, 980 μm, and 98 μm experiments, respectively.
