Abstract

This study was undertaken to assess sun-dried aqueous leaf extracts of three medicinal plants (Podophyllum hexandrum, Withania somnifera and Xanthium strumarium) against late blight of potato caused by Phytophthora infestans. Foliar sprays of 25 % (w/v) leaf extracts of the three medicinal plants at a 3 day interval significantly reduced disease severity and resulted in higher tuber yield and biological yield compared to control. Among the tested plants, leaf extracts of Podophyllum hexandrum were more effective in minimizing the disease incidence and producing better biological yield/plant (24.92 g) and tuber yield (14.93 t/ha) than other treatments. Results of this study recommends that foliar application of the tested plants extracts (at 3 d) in the order of efficiency (P. hexandrum> X. straumerium> W. somnifera) against late blight could be used for minimum disease incidence and better yields.
