Abstract
Field experiments were conducted at Itay EL-Baroud-Agricultural Research Station, Itay EL-Baroud, Beherah Governorate, Egypt, during the seasons 2020-2021 and 2021-2022. The objective was to evaluate the efficacy of tribinuron-methyl, fluroxypyr and their combinations in controlling broad-leaved weeds in wheat fields. Hand weeding was performed at 15 and 30 days after sowing (DAS), while the herbicides were applied at 15 days after sowing (DAS). At harvest, fresh and dried weed biomasses (g m-2) were measured, as well as certain agronomic wheat crop parameters such as 1000 grain weight (grams), wheat grain and straw yields (kg fed-1). The results showed that all of the tested formulations significantly reduced the biomass of weeds including both fresh and dried biomasses of annual broad-leaved weeds. Melilotus indica L., Beta vulgaris L., Sinapis arvensis L. and Cichorium pumpilum Jacq., which were the most predominant weeds in the wheat field during both seasons. Throughout the two seasons of investigation, the combinations of  tribinuron-methyl+ fluroxypyr demonstrated the most significant reduction in both weed control efficiency (WCE) and the fresh weight of annuls of broad-leaved weeds. These compositions improved all wheat crop biological parameters, including grain and straw yields, throughout the investigated two seasons, and were followed by hand weeding.
