In order to study the efficiency of Atlantis dual purpose herbicide (Mezosulfuron+ Iodosulfuron) and its blend with some herbicides for weeds controlling of wheat field weeds, an experiment has been conducted in completely randomized blocks design with 7 treatments and 4 repetitions in 2011-2012. Treatments included post-emergence application of Atlantis herbicide with two doses of 1 and 1.5 Lha-1, the blend of Atlantis herbicide with the dose of 1.5 Lha-1 + Bromicide MA with two doses of 0.5 and 1 Lha-1, the blend of Atlantis herbicides with the dose of 1.5 Lha-1 + Duplosan Super with two doses of 1 and 2 Lha-1, and weedy treatment as check. The results indicated that the blend of Atlantis with the dose of 1.5 L+ Duplosan Super with the dose of 2 L was the best opting for controlling broad leaves weed like ivy and clover, and displayed a significant differences with other treatments. After that, the blend of Atlantis with the dose of 1.5 Lha-1+Bromicide MA with the dose of 1 Lha-1showed the highest extent of control. Atlantis with the dose of 1.5 Lha-1 statistically was the best treatment to control narrow leaves weed. The highest performance of grain yield that is 6075.3 kg ha-1 obtained from blending Atlantis with the dose of 1.5 Lha-1 + Duplosan Super with the dose of 2 Lha-1. The superiority of this treatment mainly was due to the more importance of broad leaves weed in the experimental field.
