Abstract: 

IN ORDER TO STUDY THE EFFICACY OF REGISTRED HERBICIDES GRAIN CORN, AN EXPERIMENT WAS CONDUCTED AT RESEARCH STATION OF AGRICULTURE OF ESFAHAN DURING 2007 GROWING SEASON. THE EXPERIMENT DESIGN WAS A COMPLETELY RANDOMIZED BLOCK WITH FOUR REPLICATIONS AND 18 TREATMENTS. TREATMENTS WERE THE FULL–SEASON HAND WEEDED CONTROL, AND POST EMERGENCE (POE) APPLICATIONS OF 2, 4-D PLUS MCPA, BROMOXYNIL PLUS MCPA, NICOSULFURAN, AND FURAMSULFURON, PRE-PLANTING (PP) APPLICATION OF EPTC PLUS DICHLORAMIDE AND PRE-EMERGENCE (PE) APPLICATION OF PENDIMETHALINE, AND COMBINATION APPLICATION OF EPTC PLUS DICHLORAMIDE (PE) PLUS 2, 4-D PULS MCPA (POE) OR BROMOXYNIL+MCAP (POE), OR ATRAZINE (PE), ALACHLOR (PE) PLUS 2, 4-D PULS MCPA (POE) OR BROMOXYNIL+MCAP (POE), OR ATRAZINE (PE) AND ACETACHLOR PLUS 2, 4-D PULS MCPA (POE) OR BROMOXYNIL+MCAP (POE), OR ATRAZINE (PE). RESULTS INDICATED THAT 2, 4-D PLUS MCPA AND BROMOXYNIL PLUS MCPA WERE THE GOOD TO EXCELLENT OPTION TO CONTROL BROADLEAVE WEEDS. THE EFFICACY OF TWO NEW HERBICIDES "NICOSULFURON AND FURAMSULFURON", ON BARNYARDGRASS (ECHINOCHLOA CRUS-GALLI (L.) BEAUV.) WAS MODERATE TO GOOD. PENDIMETHALIAN HAD THE GOOD TO EXCELLENT EFFECTS ON BARNYARDGRASS AND BROADLEAVE WEEDS. GENERALLY, THE EFFICACY OF 2, 4-D PLUS MCPA AND BROMOXYNIL PLUS MCPA ON BROADLEAVE WEEDS WERE BETTER THAN ATRAZINE. ADDITIOINLY, ACETHALCHLOR WAS BETTER THAN ALACHLOR FOR CONTROLLING NARROW LEAVES AND BROADLEAVES WEEDS.
