We have done experiments on a field of barley where we have studied a possibility of lowering the drift FFS with using the antidrift nozzles. After applying, we have measured a share of spray deposit on the distance of 0, 1, 2, 5 and 10 meters away from the edge of the field using the fluorescent tracker. All measurements have been done in four repetitions. We have compared a perimeter of skidding with standard nozzle (Lechler LU 120-03) and three antidrift nozzles (Lechler ID 120-03, Albuz AVI – TWIN 110-03, and AGROTOP Turbodrop HiSpeed 110-03) with a deposit of 250 liters of spray deposit on hectare. A share of spray deposit that was skid lowered with the distance from the edge of the field with all measured distances. The smallest drift was achieved with the nozzle HS. The size of the droplets significantly influenced the part of the drift where the drift was the biggest with the nozzle LU (VMD = 185). When using different types of nozzles with similar sizes of droplets and approximately same speeds of wind in the time of deposit the drift is the same. Antidrift nozzles lowered the drift for 70–85% on all measured distances.

COBISS.SI-ID: 3400236In a field experiment, created in the University Centre for Agriculture (UKC) Pohorski dvor Pivola in Maribor, we have in 2012 the influence of anti-drift nozzles used (Lechler ID 120-03, 110-03 TWIN Albuz AVI and Turbo Drop HiSpeed 110-03) to the formation of the deposit according to the horizontal and the vertical of the plant of winter barley as compared with the deposition, which was molded with an improved standard nozzle (Lechler LU 120-03) studied. The highest achievement of common normalized deposits were achieved with the nozzle Turbo Drop HiSpeed 110-03 and 120-03 Lechler ID and have specifically statistically different from the debris that reaches the nozzle Albuz AVI TWIN 110-03 and 120-03 Lechler LU were. As expected, we have achieved the highest deposition in the upper third of the leaves. Surprisingly high were the values of the deposition in the lower third of the leaves that have specifically not statistically different from the values that we have reached the top third. Likewise, the deposits have reached on the ear and the middle third of the leaves are not statistically different specific with each other. The deposits on the stalk of the lowest values was expected and has also specifically statistically different from the other layers. In our experiment from all treated the nozzle Antidriftdüse has proven to be the best with the asymmetric double-beam Turbo Drop HiSpeed with which we have achieved the highest common normalized deposition on the whole plant. In some cases, there were statistically specific differences, but in most cases, only a trend of increase in the normalized deposition was evident. The highest values reached the Turbo Drop HiSpeed nozzle also to ear and in the upper part of the plant, but the lowest in the lower part of the plant. Based on the results, we found that the nozzle Turbo Drop HiSpeed is most suitable for use in cereals in the flowering period and later to protect the ear from harmful organisms.
