Weed control is an important factor for a successful potato crop. The objectives of current study were to assess the effect of herbicides and their rates of application on weeds and the crop. Test results come from a field experiment conducted between 2020–2021 to the National Institute of Research and Development for Potato and Sugar Beet Brasov, Romania. Two factors were tested: factor I - potato variety: Brasovia; factor II - five herbicides to control weeds and a control one variant (V1: Control; V2: clomazone+pendimenthalin 2.0 l/ha; V3: clomazone+ pendimenthalin 1.8 l/ha; V4: Sencor 0.9 l/ha; V5: Proman 3 l/ha; V6: Challenge 4 l/ha). The experiment was laid out in randomized complete block design with three replications. Herbicides were applied as preemergence. The weed community included Chenopodium album, Amaranthus spp., Echinochloa crus-galli, Abutilon theophrasti, Polygonum spp., Falloppia convolvulus. In both years the reported effectiveness for all registered weeds was good and very good, over 85-90% of the control and all variants treated by herbicides significantly influenced the increase in potato yield in comparison with the control variants.
