Efficiency of certain metribuzin formulations for controlling weeds in maize crop and their side effects on subsequent crops…

Field experiments were conducted during the summer seasons of 2020 and 2021 at the Experimental Farm at Itay EL-Baroud-Agricultural Research Station, Itay EL-Baroud, Beherah Governorate, Egypt, to assess the efficacy of four metribuzin pre-emergence formulations (Armada 75% W.G, Sencor 60% S.C., Tamozin 70% W.P., and Yoonimarek 70% W.G) as well as hand hoeing (t Also, the lingering influence of the utilised treatments on the success of several winter crops. The results demonstrated that all herbicide formulations significantly reduced weed biomass at 60 (DAS) as well as manual hoeing when compared to the unweeded control. Noticed during the two seasons of total weeds studied, The greatest weed control efficiency (WCE) and the biggest drop in fresh weight of annuls broad-leaved weeds were (94.77 and 93.27) and (92.792.7 and 86.59), respectively. Furthermore, hand hoeing twice (21 and 35) resulted in the greatest decrease of total weed biomass, although these herbicides provided poor control of grassy weed biomasses when compared to hand hoeing (twice). All weed control treatments boosted all agronomic tritici as weight of 100 grain, weight of ear (cob), and grain yield. Biological parameters yield wase also compared to the unweeded control. Hand hoeing twice and Sencor increased maize production and yield components throughout both seasons as compared with ather treatments.
