Abstract: 

IN ORDER TO EVALUATE THE EFFECT OF HERBICIDES USAGE ON DICHONDRA (DCHONDRA MICRANTHAS) ON TURF MIXTURE, AN EXPERIMENT WAS CONDUCTED DURING 2006 IN TEHRAN, USING RANDOMIZED COMPLETE BLOCK DESIGN WITH 4 REPLICATIONS. TREATMENTS WERE WERE 2, 4-D+MCPA AT 1.5 AND 2 L/HA, DICHLRPROP-P PLUS MECOPROP-P PLUS MCPA AT 2 AND 2.5 L/HA, BROMOXYNIL PLUS MCPA AT 1.5 AND 2 L/HA, DICLOFOP METHYL AT 2.5 AND 3 L/HA, FENOXAPROP-P-ETHYL AT 0.8 AND 1 L/HA, CLODINAFOP PROPARGYL AT 0.6 AND 0.8 L/HA, TRALKOXYDIM AT 1 AND 1.2 L/HA, SULFOSULFURON AT 27 AND 35 G/HA AND UNTREATED CONTROL. ALL TREATMENTS WERE REPEATED 3 TIMES DURING THE GROWTH PERIOD OF DICHONDRA. THE RESULTS SHOWED THAT, DICHONDRA CONTROLLED BY 2, 4- D+MCPA, DICHLRPROP-P PLUS MECOPROP-P PLUS MCPA, BROMOXYNIL PLUS MCPA MORE THAN 90 PERCENT FOR ONE APPLICATION OF MENTIONED HERBICIDES. SULFOSULFURON IS EFFECTIVE HERBICIDE FOR DICHONDRA CONTROL FOR ONE MORE APPLICATION. IT DID NOT CONTROL DICHONDRA TO ONE APPLICATION. TURF MIXTURE DID NOT DAMAGE BY 2, 4-D+MCPA, DICHLRPROP-P PLUS MECOPROP-P PLUS MCPA, BROMOXYNIL PLUS MCPA, FENOXAPROP-P-ETHYL, TRALKOXYDIM AND SULFOSULFURON. ON THE OTHER HAND, TURF MIXTURE IS SUSCEPTIBLE TO DICLOFOP METHYL AND CLODINAFOP PROPARGYL AND IT DAMAGED BY THEM.
