Effect Of Plant Part Extracts On Spore Germination Of Puccinia Purpurea Cook

Plant part extracts were applied for the control of diseases caused by microorganisms. Hence, the present investigation deals with aqueous plant extracts of three plants which were screened for their fungitoxicity against spore germination and germ tube length of Puccinia purpurea Cook. Chemical fungicide Hexaconazole 0.05% used as a standard check was found better retardants for spore germination and germ tube length. The result showed that aqueous extract of Pongamia glabra vent parts at 6, 12 and 24 hour incubation period had strong fungitoxicity followed by extract of Tridex procumbens L and Lantana camera L parts in reducing the spore germination. All plant part extracts of selected plants effect on spore germination and germ tube length over control.
