Author(s): AD Saykar, PG Borkar, Sanika Joshi and SV Pawar

Abstract: In order to find out the efficacy of different botanicals (phyto-extracts) against the leaf blight disease of Colocasia caused by Phytophthora colocasiae there were eight plants extract selected in both in vitro as well as in vivo condition namely, Nanma, Sapindus mukorossi, Manma, Neemraj, Lantana camera, Eucalyptus tereticornis, Yam bean and Vitex negundo. In an in vitro experiment among these botanicals the maximum per cent inhibition of tested pathogen (94.07%) was observed in Sapindus mukorossi seed extract which was significantly superior to rest of the all treatments. It was followed by Nanma (90.36%), Neemraj (72.58%). Among above mentioned plant-extracts from which under in vivo condition the minimum disease incidence was recorded in plot sprayed with Sapindus mukorossi (33.67%), it was followed by Nanma (37.00%) and Neemraj (39.67%). Maximum mean PDI (64.85%) was recorded in control.
