Mimosa pigra L. is an invasive species that can produce some biological compounds to control other plants. This study investigated the potential role of M. pigra L. leaf extracts in plant interference. Aqueous, 80% aqueous methanol (80% MeOH) and methanol (MeOH) extracts at different concentrations of 0, 1, 10 and 100 grams dry weight per liter were prepared and used as treatment solutions to assess their effects on plant growth and the chlorophyll content of two target weed species, Ruellia tuberosa L. and Echinochloa crus-galli (L.) P. Beauv. The experiment was done as a 3 × 4 factorial format with a completely randomized design. It was done under greenhouse conditions. The results revealed that the three different solvent extracts inhibited the growth of both tested weed species and decreased their chlorophyll accumulation. The inhibition increased for each growth parameter with increasing concentrations of each of the various solvent extracts. Among the three extracts, the 80% MeOH and MeOH extracts showed greater efficacy than the aqueous extract. These M. pigra extracts had a phytotoxic potential to control weed growth.
