Sažetak
In this research, the impact of two different spraying systems (classic and sensor with Tifone Vento 1500 air assisted sprayer) is shown on two types of drift (ground and air) and liquid deposit in the treetop. Technical spraying factors were set differently through the research according to treatments. The research was conducted according to ISO norm 22866 in a cherry orchard. With variance analysis, impact of spraying norm as factor A (A1 - 250 l ha-1; A2 - 200 l ha-1); nozzle type as factor B (B1 - Lechler TR 8002C; B2 - Lechler ITR 8002C) and air flow rate as factor C (C1 - 18 m s-1; C2 - 12 m s-1) was examined. Spraying was conducted with 4% dilution of tartazine organic dye, and drifted liquid was collected with filter papers. By optimizing the technical spraying factors, a maximum reduction of 36.59% for ground drift is achieved, as well as 75.05% for air drift at 5 m distance from the treated row. By exploiting the ultrasonic sensory system for selective application, ground drift was reduced by 43.35%. In this case the air drift at 5 m distance from the treated row was decreased by 66.57%, and 79.61% at a distance of 10 m. Maximum air drift reduction at 10 m was achieved by using an ITR nozzle for both spraying systems. The exploitation of ultrasonic sensory system did not have a negative effect on the deposit in the treetop, because no significant difference was found between these two spraying systems (0.5%). Equipping conventional sprayers with advanced systems for selective application greatly contributes to higher precision of pesticides application and with thereby reducing the negative impact on the environment.
