ABSTRACT



The 1991-1993 research aimed at defining the applicability of mechanical treatment and some herbicides for potato weed control. Mechanical treatment, 3-time hilling plus harrowing, combined with herbicides, Bladex 50 WP 2 kg.ha-1 applied till emergence and post-emergence Nabu 20 EC at 2 l.ha-1, showed most effective, causing a four-time reduction in weed infestation (weed dry matter) and increasing tuber yield by 47%, as compared with the control exposed to mechanical treatment, only.

Key words: potato, weed control, weeds, tuber yield.
