Abstract
In 2022, during the grapevine vegetation, we compared two air-assisted sprayers with different constructions for grapevine protection. The quality of pesticides application in a terraced vineyard, productivity, fuel consumption and the cost of using machines were evaluated. A classic axial air-assisted sprayer with the possibility of spraying left and right (Friuli Sprayers ATV 1000) and a radial air-assisted sprayer with four air deflectors (Friuli Sprayers Compact 1000 T4) with the possibility of spraying four walls canopy of the vine were included in the comparison. The percentage of coverage was determined with the help of water-sensitive papers. Greater coverage on the outer and inner walls of the edge rows on the terrace was achieved by using the Compact air-assisted sprayer. When using the Compact air-assisted sprayer, fuel consumption is higher due to the radial fan, which requires more drive power. Nevertheless, it can be used to achieve greater productivity, which is crucial for larger vineyard areas.
