Abstract
Faculty of Agriculture and Life Sciences conducted in 2012 a study on the effects of anti-drift nozzles (Lechler ID 120-03, Albuz AVI TWIN 110-03 and 110-03 Turbo Drop HiSpeed) on the horizontal and vertical deposit in winter barley and a comparison with the deposit achieved by standard nozzles (Lechler LU 120-03) that took place at the University Agriculture Centre agricultural experiment station Phorski Dvor near Maribor. The largest normalized deposit was measured with Turbo Drop HiSpeed 110-03 and 120-03 Lechler ID nozzles and was statistically different from the results of Albuz AVI Twin 110-03 and Lechler LU 120-03 nozzles. As expected, the largest deposit was measured on upper leaves. Only minimal deposits that were statistically different from all other parts of the plant were detected on the stem. In our experiment, the best results were achieved using the asymmetric Turbo HiSpeed nozzle. Based on the results, we found that Turbo Drop HiSpeed nozzle is the most appropriate nozzle for the disease control of barley during bloom, and for the disease and pest protection in later stages of crop development.
