Trial was carried out to survey the different rates of new generation post-emergence herbicide 'Verdict' in four levels involving: 0, 0.2, 0.3 and 0.5 kg ha-1 to suppress three weeds species; Chenopodium album, Poaceae sp. and Stelaria media. Experiment was conducted in a completely randomized design [CRD] with four treatments in four replications. Weeds growth diminished mostly for verdict 0.5 kg ha-1 and then 0.3 kg ha-1 compared to 0.2 kg ha-1 and control, results of the trial revealed that a satisfactory survival reduction of Chenopodium album, poaceae and also Stelaria media were achieved with labeled-dose of verdict as 0.5 kg ha-1 and also intermediate dose 0.3 kg ha-1. In contrast, the minimum dose 0.2 kg ha-1 had a significantly highest weeds survival about three varieties of mentioned weeds in comparison with other higher doses of herbicide.
