Sažetak
This study investigated the influence of travel speed (6 and 10 km/h) and spray angle (-30°, 0° and +30°) on leaf surface coverage (LSC), on the area not treated (drift) and on droplet size. The leaf surface coverage, size and number of droplets, as well as the drift intensity, were determined using water-sensitive papers (WSP) that were scanned and processed with the DepositScan program. Research has shown an influence of working velocity and spray angle on LSC and drift. While the spray angle had very little effect on the droplet diameter, it had a significant effect on the LSC, where -30° adjustment had the lowest coverage on the treated surface and the highest drift, both at 6 and 10 km/h. The working velocity also had an impact on both LSC and droplet diameter, where a higher speed resulted in less coverage on the treated surface and higher drift.
