Abstract
In order to evaluate the effect of four herbicides (Ethalfluralin, Trifluralin, Pendimethalin and Metribuzin) of potato fields in IRAN for control of Lambsquarter (Chenopodium album) and redroot pigweed (Amaranthus retroflexus), an experiment was conducted at the green house of Mohaghegh Ardabili University in 2008. A dose-response study was conducted based on completely randomized design with four replications. The potato cultivar was Agria. Herbicides were used in six doses including recommended dose, higher and lower doses. All herbicides were sprayed pre-emergence. Results showed that ranking of these herbicides for weed control were Ethalfluralin, Metribuzin, Pendimethalin and Trifluralin, respectively. Also ranking of herbicides for potato safety were Metribuzin, Trifluralin, Pendimethalin and Ethalfluralin respectively.

Keywords: Ethalfluralin, Trifluralin, Pendimethalin and Metribuzin
