Abstract: 

TO STUDY THE EFFECT OF CLOPYRALID AND GLYPHOSATE AND THEIR MIXTURES TO CONTROL ACROPTYLON REPENSE A FIELD TRIAL WAS CONDUCTED IN COMPLETELY RANDOMIZED BLOCK DESIGN WITH 35 TREATMENTS (IN DOSE-RESPONSE ARRANGEMENTS) AND THREE REPLICATIONS IN SPLIT-SPLIT BLOCK DESIGN AT GOLMAKAN, KHORASAN RAZAVI, IRAN, IN 2007. TREATMENTS WERE GLYPHOSATE ALONE AT DOSES OF 0, 1, 2, 3, 5, 7 AND 10 1/ HA, CLOPYRALID ALONE AT DOSES OF 0, 100, 200, 300, 500, 700 AND 1000 ML/ HA, 50% GLYPHOSATE (AT DOSES OF 0, 0.5, 1, 1.5, 2.5, 3.5 AND 5 1/ HA, RESPECTIVELY) +50% CLOPYRALID (AT DOSES OF 0, 50, 100, 150, 250, 350 AND 500 ML /HA, RESPECTIVELY), 25% CLOPYRALID (AT DOSES OF 0, 25, 50, 75, 125, 175 AND 250 ML / HA, RESPECTIVELY) +75% GLYPHOSATE (AT DOSES 0, 0.75, 1.5, 2.25, 3.75, 5.25, 7.5 1/ HA) AND 25% GLYPHOSATE (AT DOSES OF 0, 0.25, 0.5, 0.75, 1.25, 1.75 AND 2.5 L/ HA , RESPECTIVELY) +75% CLOPYRALID (AT DOSES 0, 75, 150, 225, 375, 525 AND 750 ML /HA, RESPECTIVELY). HERBICIDES WERE SPRAYED BY MATABI SPRAYER WITH CONE NOZZLE AND BY CONSIDERING 400 L / HA HERBICIDE SOLUTION. WEED CONTROL ASSESSED VISUALLY AT 30 DAYS AFTER TREATMENTS AND WEED DENSITY AND WEED DRY MATTER WERE DETERMINED IN EACH PLOT. RESULTS SHOWED CLOPRALID AT DOSES OF 700 AND 1000 ML HA AND GLYPHOSATE AT DOSES OF 7 AND 10 L HA CONTROLLED ACROPTYLON REPENSE COMPLETELY. BY INCREASING THE CLOPYRALID RATIO IN MIXTURES (75% CLOPYRALID+25% GLYPHOSATE) CONTROL OF ACROPTYLON REPENSE INCREASED REMARKABLY.
