Abstract

 Taro leaf blight caused by Phylophthora colocasla Raciborski is the most destructive disease of taro (Colocasla esculenta (L.) Schott) worldwide. The antimicrobial activity of ethanolic leaf extract of Senna alata. Justicia secunda, Chromolaena odorata, and Aloe barbadensis against P.colocasia were investigated at different percentage of lOOpg/ml, 50gg/ml and 25pg/ml.The result showed that only ethanolic leaf extract of C.odorata and S.alata inhibited the growth of the orgamsm.The mean inhibition diameter recorded for S.alata at lOOgg/ml, 50gg/ml and 25gg/ml are 5.5±6.63, l±0.0 and 0.0 respectively. C.odorata at these concentrations gave 10.5±0.70. 6.6j±5.5 and 1 ±0.0. Phytochemical screening of the extracts revealed the presence of Tannis, Saponins, Alkaloids. Flavoids and Steroids. These findings suggest that C.odorata and S.alata could serve as potential source of bio-fungicides for the control of Taro leaf blight.
