Summary
Der er udført forsøg to steder i to år med rullestjernerenseren i kartofler. Formålet har været at finde det mindste antal behandlinger for at minimere afgrødeskade og maximere effekten på både enårigt og flerårigt ukrudt. Behandlingerne blev udført på ukrudtets trådstadie, kimbladsstadie eller løvbladstadie. Det tilsvarende antal behandlinger var 4 eller 6, 2 eller 3 og 1 eller 2. Effekten på biomasse af enårigt ukrudt var over 80% med en overkørsel og over 90% med to. Effekten på biomasse af flerårigt ukrudt var over 50% med mere end en overkørsel. Kun i ét forsøg blev udbyttet reduceret (ca. 10%) ved mekanisk bekæmpelse sammenlignet med kemisk, mens der var 50% udbyttetab i de ubehandlede parceller. Flere behandlinger havde en tendens til at reducere udbyttet.

Summary translation
Experiments have been carried out at two locations in two years in Denmark with the rolling cultivator in potatoes. The objective has been to find out what the minimum number of treatments are to minimise crop damage and to maximise the control effect on annual and perennial weeds. The treatments with the rolling cultivator were carried out at the weed stages of pre-emergence, cotylodon and true leaf. The corresponding number of passes with the implement was 4 or 6, 2 or 3 and 1 or 2. The effect on weed biomass of annual weeds was above 80% with one pass, and above 90% with two passes. The effect on biomass of perennial weeds has been above 50% with more than one pass with the implement. Only in one experiment the yield was reduced (10 %) by mechanical weed control as compared to herbicide weed control, while there was above 50% yield reduction in the untreated plots in all experiments. More treatments tended to reduce yield.
