Abstract
This paper deals with the results gathered from the control practices in the forestry nurseries on the two-year-old oak saplings, using portable spraying equipment (Stihl SR 420), when we sprayed three adjacent rows at a passage. In the context of three rows sprayings, we determined the surface of the drops on a cm2, the number of drops on a cm2, the coverage percentage, the arithmetic mean of the number of drops on the eighteen sample markets and the total number of drops that fell on the top, the middle and the bottom of the sapling, both on the superior and inferior part of the leaf.
