In order to compare efficacy of Pantera (quizalofop-P-tefuryl 4%EC) with other graminicides in canola fields of Fars province, an experiment was carried out in randomized complete block design with 4 replication and 11 treatments in Darab research station in 2008-2009. Treatments included Pantera at 1, 1.5 and 2 lha -1, Galant super (haloxyfop-R-methyl aster) at 0.75 lha -1, Focus (cycloxydim) at 2 lha -1, Treflan, (trifluralin 48% EC) at 2 lha -1, Butisan star (metazachlor 33.33%+quinmerac 8.8%) at 2.5 lha -1, Treflan at 2 lha -1+Pantera at 1.5 lha -1, Treflan at 2 lha -1+Galant super at 0.75 lha -1, Treflan at 2 lha -1+Focus 2 lha -1 and full season weed control as check. Results showed that 2 lha -1 Pantera in compare with Treflan+other graminicides as super gallant, focus and Pantera and full season weed control treatment had no significant difference and increased canola yield by 39.5-41.7%. Also, 2 lha -1 Pantera controlled wheat, barley, wild oat and ryegrass. In 100, 100, 90.97 and 92.92 percent respectively and 75.4 percent in decreasing of dry weight of grasses.
