Screening the nematicidal potential of indigenous medicinal plant extracts against Meloidogyne incognita under lab. and greenhouse conditions

Abstract Background The root-knot nematode, Meloidogyne incognita , causes a high damage and yield decrease for many economic plants. need non-systemic effective new approaches environmentally friendly methods controlling the nematodes has directed research to some safe agrochemicals found in medicinal plants as viable management options. Results In laboratory experiments, solidago periwinkle aqueous ethanolic extracts achieved J2 mortality (%) concerning different dilutions; however, were more than extracts. Also, there was direct relationship between nematicidal activity of these with both concentration time application. Inhibition egg hatching by Periwinkle higher that solidago. Moreover, tested against decreased significantly prolonged storage at + 5 °C, while did not stored frozen – °C 12 months. killed non-target organisms, i.e., rotifers free-living nematodes. Seventy-five 90% total phytochemicals recovered from solidago, respectively nematostatic or nematode viability, hatch vitro, development reproduction vivo despite method application (foliar soil drench). antagonistic effects pronounced drench their concentrations Conclusion Solidago plant showed important sources control M. .
