Effects of Some Mixed Ligand Metal Complexes Against the Fungal Disease of Tomato Caused by Fusarium oxysporum F. Sp. lycopersici in Natural Epiphytotics.

Abstract :

&nbsp;A series of mixed ligand transition metal complexes of Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) with ligands&nbsp;

picric acid and 1, 10 phenanthroline have been designed, synthesised and screened individually on fungal pathogen Fusarium oxysporum f. sp. lycopersici, an important multi drug resistant pathogenic species which attacks&nbsp;

on tomato plants. The general composition of these complexes is MX2Y2. Where M stands for bivalent metal ion, X for&nbsp;

picrate ion and Y for phenanthroline. All the metal complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, electronic spectra and IR spectroscopy. Cu (II) complexes were additionally characterized by EPR spectral studies. On the basis of spectral studies octahedral geometry has been assigned to&nbsp;

these complexes. To achieve a better pharmacological profile in vitro and in vivo antifungal screening of these complexes were done. Antifungal screening indicates that the complexes show enhanced antifungal activities against the&nbsp;

fungal strains as compared with parent compounds.
