Synergistic Effect of Antifungal Activity of Medicinal Plants with Transition Metal Ferrocyanides

Manganese cobalt, nickel, copper, zinc and cadmium ferrocyanides were synthesized and characterized by IR spectra, magnetic susceptibility and elemental analysis studies. The natural antifungal plants such as Azadirachta indica, Cassia alata, Vitex negundo and Neriun oleander were showed synergistic effect with transition metal ferrocyanides. The natural antifungal plant extracts with metal ferrocyanides complexes were found to be having more antifungal property in comparison to metal ferrocyanides and plants extract alone. Antifungal activities of natural antifungals, metal hexacyanoferrate (II) compounds were tested against Rhizoctonia solani causing black scurf in potato. Cadmium ferrocyanide with Azadirachta indica extract and nickel ferrocyanide with Cassia alata extract complexes were found to have maximum and minimum antifungal property, respectively.
