Efficacy of some plant extracts on Spore Germination of Phakopsora Pachyrihzi Sydow Dhanaji Pawar Department of Botany, M. H. Shinde Mahavidyalaya, Tisangi Tal-Gaganbavada Dist-Kolhapur416 206, Maharashtra, India Online published on 27 May, 2021. Abstract Traditionally plant extracts were applied for the control of diseases caused by microorganisms. Hence, the present investigation deals with aqueous plant extracts of ten plants which were screened for their fungitoxicity against Phakopsora pachyrhizi. Inhibition of spore germination and germ tube length of Phakopsora pachyrhizi was tested. Propiconazole 0.1% used as a standard check was found better retardants for spore germination and germ tube length. Extracts of Nerium oleander L and Lantana camara L at 1 to 12 hr incubation period were highly effective in reducing the spore germination and germ tube length. Among the treatments Parthenium hysteropehorus L leaf extract exhibited less inhibitory effect against Phakopsora pachyrhizi. All the leaf extracts of ten plants showed better inhibitory effect on spore germination and germ tube length over control (Distilled Water) Top Keywords Phakopsora pachyrhizi, Plant extracts, Fungitoxicity, Propiconazole, Spore germination.
