Abstract
Leaf extract of Azadirachta indica, Atropa belladonna, Calotropis procera, Ocimum basilicum, Eucalyptus amygdalina, Ailanturs excelsa [Ailanthus excelsa] and Lantana camara at 20, 40, 60, 80 and 100% concentrations and fungicides Bavistin [carbendazim], Dithane M-45 [mancozeb], captan, thiram and Topsin M [thiophanate-methyl] at 0.2% concentration were tested against Fusarium oxysporum inducing fenugreek wilt under pot house conditions. Seeds of fenugreek were soaked overnight in each leaf extract and fungicidal solutions. Results revealed that all the leaf extracts, except that of Ailanturs excelsa, showed significant effect over control. The maximum germination of fenugreek seeds was observed with Atropa belladonna (90.66%), followed by Azadirachta indica (87.99%) and L. camara (87.99%), being more pronounced at higher concentrations than at lower concentrations. Leaf extract of Ailanturs excelsa showed phytotoxic effect, reducing the seed germination by 39.99%. The maximum germination of fenugreek seeds was observed with Bavistin (93.33%), followed by Atropa belladonna, Azadirachta indica and L. camara and significantly effective over the leaf extracts of C. procera (85.99%), O. basilicum (85.33%) and E. amygdalina (82.40%). Dithane M-45 (80.00%) was at par with the leaf extracts. Captan (86.66%), thiram (86.66%) and Topsin M (86.66%) were at par with all the leaf extracts except that of Ailanturs excelsa.
