ABSTRACT:
Newly synthesized 1-(2, 4-Dihydroxyphenyl) Ethanone ligand and its Co(II), Ni(II), Zn(II) and Pd(II) metal complexes were tested for their fungicidal potentials against Gibberela, Cercospora arachidicola, Physolopora piricola and Fusarium oxysporium. Preliminary in vitro test for fungicidal activity of the ligand and complexes were carried out by the fungi growth inhibition method. In general, the ligand and the complexes displayed certain activity against the fungi species at 25ppm, 50ppm and 100ppm. The complexes are more toxic to the fungi species than the uncomplexed ligand at different concentrations. The inhibition percentage of the ligand and complexes increases as the concentration increases. The metal complexes show more increased activity than the corresponding ligands.
