Wheat (Triticum aestivum L.) and its associated weeds were grown in an experiment at two sites in Nineveh during the agricultural season of 2021-2022. The first site was in the Al-Hamdaniya/ Al-Balawat village, district, 40 km southeast of the city center. The second site was in the Tal Kaif / AL-abbasiya district, 15 km north of the city center. Control treatment was LIMITLESS-25 (25% less than the recommended concentration, 75% a.i. of the recommended concentration), LIMITLESS R.C. (100%, a.i. the recommended concentration), and LIMITLESS +25 (more than the recommended concentration by 25% a.i.). The experiment included two wheat varieties (Tal Afar 3 and Wafia) and three concentrations of LIMITLESS WG Herbicide. We employed a factorial experiment design (split-plot) for our study, with herbicides in the main plot and cultivars in the sub-plot, and we compared the means of the treatments with Duncan’s multiple range test. Weed total weight and efficiency ratio were both reduced to record lows by the Limitless R.C. and Limitless + 25 at the Al-Balawat site, and by the Limitless + 25 at the Telkif site, where the latter achieved a ratio of 49.21%. The maximum yield was found in Telkif for Limitless R.C., which was 260.578 g/m-2.
