Worldwide grain yield in maize may be severely impacted by competition with weeds. To evaluate the efficacy of novel herbicide formulations for weed control in maize, a randomized complete block design trial comprising three replications and seven treatments was carried out at the experimental field of the Agricultural and Research Station Caracal in 2023 year. All of the treatments, which were made up of separate and related herbicides, were considered to be selective in maize after emergence (POST). Their effectiveness was evaluated at 7, 14, 21, and 28 days after each treatment targeting the most common weeds, such as HIBTR, DIGSA, SOLNI, ATRPL, AMARE, CONAR, POROL, XANTIST, CIRAR. The findings indicated that of the herbicidal treatments, the best efficacy was recorded by Click Trio (2 L/ha) with efficacy between 80-100% even at 7 days after treatment for most of the targeted weeds. Also, a good control of targeted weeds from maize crop was done by Pyxides WG 562.5 g/kg + Adigor ADJ and the combination SAE 0.53 H/01+ Baracuda controlled weeds 100% especially at 14, 21 and 28 days after treatment, excepting Convolvulus arvensis (CONAR), Hibiscus trionum (HIBTR).
