Abstract: 

AN EXPERIMENT WAS CONDUCTED IN QAZVIN PROVINCE DURING 2006-2007 TO INVESTIGATE EFFICACY OF DIFFERENT DOSES OF BUTISAN STAR (METAZACHLOR+QUINMERAC) 41.6% SC. IN CANOLA FIELDS. THE EXPERIMENT WAS RANDOMIZED COMPLETE BLOCK DESIGN WITH 3 REPLICATIONS AND THE FOLLOWING TREATMENTS: BUTISAN STAR AT 2, 2.2, 2.5, 3, 4 AND 5 L/HA PRE-EMERGENCE AND AT COTYLEDON STAGE OF CANOLA, TREFLAN (TRIFLURALIN 48% EC) AT 2 L/HA PRE PLANT INCORPORATED+GALANT SUPER (HALOXIFOP-RMETHYL ESTER, 10.8% EC) AT 0.75 L/HA BEFORE STEM ELONGATION OF GRASSY WEEDS, AND WEEDY CHECK. EACH PLOT WAS DEVIDED INTO TWO SECTIONS. THE UPPER HALF WAS CONSIDERED AS WEEDY CHECK AND THE LOWER HALF WAS TREATED. DATA COLLECTED FROM TREATED AREA WAS COMPARED WITH THE WEEDY SECTION OF THE SAME PLOT. RESULTS INDICATED THAT ALL TREATED PLOTS SHOWED YIELD INCREASE AS COMPARED TO WEEDY CHECKS. THE HIGHEST YIELD INCREASE WAS 42-45 %, OBSERVED IN 2.2 – 4 L/HA OF PRE – EMERGENCE BUTISAN STAR AND WEEDLESS CHECK WITH NO STATISTICAL DIFFERENCE AMONG THEM. YIELD INCREASE IN OTHER TREATED PLOTS VARIED BETWEEN 3-16%. IT WAS CONCLUDED THAT FOR WEED CONTROL IN CANOLA FIELDS WE CAN RECOMMEND 2.2 L/HA OF PREEMERGENCE BUTISAN STAR AND WE MAY EXPECT ABOVE 40% YIELD INCREASE.
