Synthesis of Metal Complexes of Schiff Bases and their Nematicidal Activity Against Root Knot Nematode Meloidogyne incognita

Six metal complexes were synthesized from Cd (II), Mn (II) and Zn (II) chloride and ligands 2-((3- nitrophenylimino)methyl)phenol (HL1) and 2-((4-nitrophenylimino)methyl)phenol (HL2) in 1:2 M ratio. Microanalytical data, UV-Visible spectral data, magnetic susceptibility, IR, 1HNMR, 13CNMR, mass and molar conductance measurements were used to characterize the structure of complexes. The complexes were found to be non electrolytic on the basis of molar conductance studies. The Schiff bases and their metal complexes had also been screened for their antinemic activity against root knot nematode, Meloidogyne incognita. Complexes have shown significant antinemic activity than their corresponding Schiff bases.
