This study was conducted to eliminate the weeds accompanying the maize crop in Al- Rashidiya region in one of the northern suburbs of Mosul, Nineveh province, during the 2021 season in the northern region of Iraq, to evaluate the efficiency of a selectivity herbicide newly introduced into Iraq. The study included two factors: the first factor was the use of the herbicide (Adengo) in three concentrations (200, 300, 400 ml.ha-1) and a free weeds treatment (hoeing throughout the growing season) and the control treatment. As for the second factor, two cultivars of maize were used, the first (local, government cultivar) and the second, an imported hybrid (Dk 5060), as seasons were included as a third factor in the aggregate analysis. Statistical analysis was conducted by Randomized Complete Block Designs according to the factorial experiment system, and Duncan's multiple-range test was used using the computer according to the (SAS) program .The results were summed up with the adengo herbicide at a concentration of (400 ml. H) which showed significantly excelled in eliminating narrow and broad-leaved weeds and reducing them when flowering. The efficiency of the adengo herbicide was equal at a concentration of (300, 400 ml. ha-1) as it did not differ significantly despite the excelled of the concentration (400 ml.ha-1) in the autumn season. In addition to the excelled of the herbicide at a concentration of (400 ml.ha-1) in most growth and yield traits. The use of the herbicide at a concentration higher than the recommended led to an increase in weed killing, where its efficiency in reducing the dry mass of the weeds was (71%) and its efficiency in reducing the density of the weeds was (75%) compared to the weed control treatment. at a concentration of (400, 300) ml.ha-1 in the case of leaves area, The autumn season showed a significantly excelled on the spring season in terms of grain yield and protein yield.It was also noted that the quantity of yield increased when using adengo herbicide at a concentration of (400 ml.ha-1) in the autumn season by (40%) for the imported cultivar compared to the control treatment and for the local cultivar by (16%). As for the autumn season of the imported variety, the increase was by (26%) and for the local one by (19%) also compared to the control treatment, and the increase in the grain yield of the imported variety in the autumn season compared to the control treatment in the autumn season of the local cultivar amounted to (54%).
