The present research work consisted of a laboratory bioassay to determine the inhibitory effect of the aqueous extract of the mesocarp of Sapindus saponaria L. on the preemergence of the seeds of Elephantopus mollis H.B.K. and Bidens pilosa L. weeds. The research was carried out at the Botany and Dendrology Laboratory of the National University of San Martin, using five concentrations of aqueous extract (5%, 10%, 15% and 20%) as treatments, distributed in a completely randomized statistical design (CRD), differences between treatments were analyzed using Duncan's statistic (p<0.05). The indicators of Relative Seed Germination Percentage, Relative Radicle Growth Percentage and Germination Index (GI) Percentage were evaluated to determine the level of phytotoxicity. At a concentration of 20% aqueous extract of Sapindus saponaria L., a greater inhibitory effect was found on the Relative Seed Germination (RSG) of Elephantopus mollis H.B.K and Bidens pilosa L. with 14.29% and 24.44% respectively, as well as on Relative Radicle Growth (RRG) with 1.36% for Elephantopus mollis H.B.K. and 2.04% for Bidens pilosa L. The Germination Index (GI) of 0.19% and 0.50% indicate that the aqueous extract has severe toxicity levels on the seeds of the weeds studied.
