Abstract
Effect of seeds powder of Azadirachta indica A. Juss, Adenanthera pavonina L., Leucaena leucocephala (Lam.) de Wit and Eucalyptus spp., in the control of root rot diseases caused by Macrophomina phaseolina (Tassi) Goid, Rhizoctonia solani Kühn and Fusarium spp., on mung bean (Vigna radiata L.) and chick pea (Cicer arietinum L.) plants were examined. The results obtained from screen house application of A. pavonina, L. leucocephala and Eucalyptus spp., @ 0.1 and 1% w/w showed significant control of root rot fungi viz., M. phaseolina, R. solani and Fusarium spp., and enhanced plant growth in term of shoot length, shoot weight, root length and root weight on mung bean and chick pea. There was complete suppression of Fusarium spp., and R. solani infection on mung bean when soil was amended with seeds powder of A. pavonina @ 1% w/w. Of the four local trees seed powder used, A. pavonina and Eucalyptus spp., @ 0.1 and 1% w/w reduced the infection of root infecting fungi followed by L. leucocephala and A. indica.
