Abstract
A field experiment was carried out during the 2022-2023 agricultural season at the research station of the Field Crops Department- College of Agriculture- Tikrit University. The aim was to increase the efficiency of narrow-leaf herbicides to control wild barley weed (Hordeum spontaneum) in wheat fields (Triticum aestivum L.). The experiment included two factors. The first factor was weed herbicides of both Axial and Topik with recommended and half of the recommended concentration in addition to weedy treatment (Control). The second factor was Tecnophyt PH with two concentrations of 75 and 150 ml per 100 liters in addition to the treatment with distilled water only. The design was RCBD, and means were compared with Duncan’s multiple range test at 5%.
Results of the study:
The highest values (69.49% and 70.40%) in terms of weed control percentage was recorded with the treatment of Axial and Topik at the recommended concentration, respectively. While weedy treatment recorded the lowest value of 47.41%.
