This study was conducted in 2008 at the research field of University of Tehran, Karaj. The experiment was designed as a randomized complete block design with three replications. Treatments were: atrazine 1kg/ha, alachlor 4kg/ha, atrazine+alachlor (1+4) kg/ha, nicosulfuron 80 g ai/ha, furamsulfuron 45g ai/ha, rimsulfuron 25g ai/ha, nicosulfuron+furamsulfuron (80+45) g ai/ha, nicosulfuron+rimsulfuron (80+25) g ai/ha, furamsulfuron+rimsulfuron (45+25) g ai/ha, weedy and weed checks as controls. Results showed that at 15 and 30 days after treatment, maximum reduction in weed density was observed with atrazine+alachlor, atrazine and alachlor and maximum reduction in weed biomass was observed with atrazine+alachlor and nicosulfuron. The effect of plant pattern was significant on density and biomass of weeds in 30 days after treatment.
