In vitro evaluation of botanicals against blast of foxtail millet caused by Pyricularia setariae

Abstract

Foxtail millet is a highly nutritious crop affected by several diseases, of which leaf blast is an important disease, hindering productivity. The present study was conducted to evaluate the in vitro efficacy of different botanicals. Nine botanicals extracted from different plants are evaluated under in vitro condition by using Poisoned food technique. these different plant extracts were tested at three (10, 20 and 30 %) concentrations among these botanicals highest mycelial growth inhibition showed by eucalyptus (82.74 %) at 30 % concentration followed by jamun (65.45 %) at 30 % concentration and least mycelial growth inhibition observed in ashoka plant extract (12.23%) at 10 % concentration.
