Sažetak
The quantity of droplets has no significant effect on the pesticide coverage at lower and middle working speeds. This is more significant at higher working speeds. The bigger the droplet quantity, the more decreased the coverage. This is due to the additional disintegration of droplets, which produces more evaporated and air drifted droplets, and the rest of them are not sufficient enough to achieve an efficient coverage. The effect of the droplet size expressed as the median diameter is insignificant considering the coverage at lower and middle speeds. In order to achieve more efficient coverage, and especially in the case of the protection against diseases and poorly movable pests in which case the whole plant is being „ bathed” , it is necessary to decrease and maintain the working speed within the range of 1.67-2.0 ms-1 (6.0-7.2 kmh-1).
