Chenopodium album is an invasive weed in wheat fields in Egypt. The present study indicated the potentials for utilization of MILAE (Mangifera indica leaves aqueous extract) at different concentrations (5%, 10%, 15% and 25%) to suppress the germination and growth of C. album in Petri dish experiment Results indicated that predictable degrees of inhibition in C album germination and growth rate of seedlings were accompanied with the increase in the concentration of MILAE. PL (Plumule) and RL (radicle) lengths of C. album were negatively affected as the concentration of MILAE increased and the effect was prominent at 25% extract concentration. This study recommended the use of MILAE as strong phytotoxic potential allelochemicals. an alternative bioherbicides, since its leaves extract possess 展开更多
