In-vitro nematicidal activity of selected medicinal plant extract against Meloidogyne incognita

Meloidogyne incognita is a widespread pathogen that parasitises vegetables and other crops, reducing yields worldwide. The present study evaluates the nematicidal properties of Aegle marmelos (leaves and fruit) and Tinospora cordifolia (stem) extracts against Meloidogyne incognita under in-vitro conditions. Second-stage juveniles (J2s) were treated with different concentrations (0.5%-8%) of the extracts and observations were taken after 24, 48 and 72 h of exposure. A significant finding unveils that A. marmelos (leaf) extract exhibited the highest mortality rate 86.48% at 8% concentration; followed by 82.74% in T. cordifolia (stem) extract and 67.04% in A. marmelos (fruit) extract at 4% concentration. These results underscore the diverse nematicidal activity within plant extracts, shedding light on the potential applications in various fields. Further research and field trials are still required to validate the practical applicability of these plant extracts, paving the way for environment-friendly nematode control in agriculture.
