Abstract: 

IN ORDER TO INVESTIGATE THE RESISTANCE OF RYEGRASS TO CLODINAFOP PROPARGYL, GREENHOUSE TRIALS WERE CARRIED OUT DURING 2007. TREATMENTS INCLUDED SEVEN RYEGRASS BIOTYPESSUSPECTED TO RESISTANT TO CLODINAFOP PROPARGYL AND A SUSCEPTIBLE BIOTYPE COLLECTED FROM FARS PROVINCE. DOSE RESPONSE WAS CONDUCTED USING 9 DOSES OF CLODINAFOP PROPARGYL (0-32 TIME OF RECOMMENDED DOSE). NUMBER (DRN) AND DRY WEIGHT (DRD) OF SURVIVED RYEGRASS AFTER HERBICIDE APPLICATION WERE ALSO MEASURED IN DOSE RESPONSE TEST. RESULTS INDICATED THAT ALL SUSPECTED BIOTYPES WERE RESISTANCE TO CLODINAFOP PROPARGIL AND RF2, RF4, RF6 AND RF1 SHOWED HIGHEST RESISTANCE TO CLODINAFOB PROPARGIL.
