SCREENING OF SOME WEEDS AGAINST SEED–BORNE FUNGI OF PIGEON PEA [CAJANUS CAJAN (L.) MILLSP.].

Jalander, V. , M. Mamatha

Abstract :

In the present study leaf extracts from 15 weed plants such as Acalypha indica L., Achyranthes aspera L., Alternanthera sessilis (L.) R. Br. Ex. DC., Cassia tora L., Croton bonplandianum Baill., Datura stramonium L., Euphorbia hirta L., E. heterophylla L., Hyptis suaveolens(L.), Parthenium hysterophorous L., Sida cordifolia L., Solanum xanthocarpum Schrad. & H. Wendl., Tephrosia purpuria (L.) Pers., Tridox procumbens L. and Xanthium strumarium L. were tested for their antifungal activity (in–vitro) against seed–borne fungi of pigeon pea [Cajanus cajan (L.) Millsp.]. All the alcoholic leaf extracts showed good inhibitory activity against seed borne fungi and increased percent of seed germination, root & shoot length and vigour index. Alcoholic leaf extracts prepared from X. strumarium and D. stramonium leaves were showed good inhibitory activity against the seed borne fungi. 98% of seed germination was observed in seeds treated with alcoholic leaf extract of X. strumarium. The highest vigour index was recorded after the application of alcoholic and aqueous extracts prepared from X. strumarium and D. stramonium while the lowest was observed in case of untreated seeds of pigeon pea (control).
