In vitro effects of plant extracts and fungicides to control wilt of brinjal (Solanum melongena l.)

Abstract

Five fungicides viz., Bavistin DF, Capvit 50 WP, Dithane M‐45, Greengel 72
WP and Tilt 250 EC were selected to evaluate in vitro efficacy against Fusarium
oxysporum and F. solani at 100, 200, 300, 400 and 500 ppm following poisoned
food technique. Bavistin, Capvit and Tilt were found to be most effective
inhibitor against the test pathogens isolated from brinjal wilt. Bavistin and Tilt
completely inhibited the growth of F. oxysporum and F. solani at all the tested
concentrations. Out of five plant extracts, Allium sativum identified as the
promising botanical fungicide for testing against wilted plants of brinjal. The
result of present study will be helpful in suggesting some effective plant extracts
and fungicides for controlling wilting of brinjal.
