In order to evaluate the effect of Rimsulfuron, EPTC (Eradican), oxadiargyl, metribuzin and Metribuzin herbicides for controling of Lambsquarter (Chenopodium album) and prostrate pigweed (Amaranthus retroflexus), an experiment was conducted at the Mohaghegh Ardabili University green house in 2008. A dose-response assay was conducted based on completely randomized design with four replications. The potato cultivar was Agria (common cultivar in Ardabil). Herbicides were used in six doses included reduced and overdoses rather than recommended doses. Common lambsquarter and prostrate pigweed were sprayed during the 2-4 leaves stage and potato was in 15-20 cm. Results showed that the most effective herbicides for weed control were Metribuzin, Oxadiargyl, Rimsulfuron and EPTC, respectively. Also the least herbicides damage for potato was in Rimsulfuron, EPTC, Oxadiargyl and Metribuzin, respectively.
