Abstract

Pea root rot caused by Fusarium solani f. sp. pisi has been observed as an alarming problem in pea growing regions of Himachal Pradesh and poses major constraints in pea cultivations. The alcoholic leaf extracts of four plants viz., Eupatorium adenophorum, Eucalyptus sp., Vitex negundo and Ageratum conyzoides were evaluated at different concentrations for their efficacy against F. solani f. sp. pisi under in vitro conditions. Among all extracts, E. adenophorum yielded maximum mycelial inhibition of 77.4 per cent followed by Eucalyptus sp. 74.9 per cent at 25 per cent test concentration. Thus, among all test botanicals, E. adenophorum was found the most efficient against F. solani f. sp. pisi. These findings suggest that E. adenophorum extracts could be used as eco-friendly alternatives to control Fusarium solani f. sp. pisi.
