Abstract
This study focused on the nematicidal potential of sea urchin-like zinc oxide nanometrics
(SUZN) against the root-knot nematode Meloidogyne incognita. XRD, SEM, UV-vis spectroscopy,
TEM, and EDX have been utilized to characterize the SUZN. Various SUZN concentrations
(150–750ppm) were examined for their implications for M. incognita second-stage juveniles
(J2s) and egg masses, including mortality as well as hatching inhibition. The largest J2s
hatching inhibition (83.07%) was seen at 750ppm SUZN after 48hours of incubation, whereas
the lowest hatching occurred at 150ppm when compared to the control. SUZN illustrated
increased nematicidal efficiency with increasing concentration and incubation duration. LC50
values for J2s were calculated at various time points. In root-dip trials, all SUZN doses
substantially reduced J2s penetration into eggplant roots relative to the untreated control.
The study emphasizes SUZN’s strong nematicidal activity against M. incognita, suggesting its
promise as a long-term alternative to chemical nematicides for root-knot nematode
management while reducing the environmental concerns associated with traditional pesticides.
