Plant-parasitic nematodes are considered difficult to control and cause oxidative stress in host plants, thus affecting agricultural crops. In Musa paradisiaca crops, the most abundant and with the greatest impact are Radopholus similis, and Meloidogyne spp. The control method most used is chemical nematicides, usually nonspecific and harmful. In this study, objective was determined antioxidant activity and nematicidal activity from Piper cumbricola and Piper eriopodon. The results for radicals-scavenging of the ethanol extract at 500 ppm of leaf from P. cumbricola were 94% DPPH• and 92.7% in ABTS•+ and for extract of leaf from P. eriopodon at 500 ppm were 64.9% DPPH• and 67.6% in ABTS•+. The nematicidal activity was determined on Radopholus sp. and Meloidogyne spp. Mortality percentages of crude extracts above 60% were obtained after 48 h in all treatments. Fraction 3 rich in 2,4-dimethoxy-5,6-methylenedioxy-1-(2-propenyl) benzene, from P. cumbricola and fraction 4 rich in gibbilimbol B (4-[3É)-decenyl] phenol), from the P. eriopodon, showed the highest biocidal activity on Meloidogyne spp. (70–100%) and Radopholus sp (35–100%). In conclusion, the species P. cumbricola and P. eriopodon can be an efficient strategy for the control of endoparasites Radopholus spp. and Meloidogyne spp with potential antioxidant on Musa paradisiaca crops. •Plant-parasitic nematodes (PPN) are one of the major causes of economic losses in agriculture worldwide.•In Musa paradisiaca crops, the most abundant and with the greatest impact are Radopholus similis, and Meloidogyne spp.•Compound that have been extracted from Piper species have potential biological control.•The nematicidal activity of extracts and compounds of Piper have a potential inhibitory effect on Meloidogyne spp. and Radopholus sp., phytoparasites of Musa paradisiaca.
