Abstract
Efficacy of different fertilizers alone or in combination with Avicennia marina plant parts viz., leaves, stem and pneumatophore powder in the control of root rot diseases of okra and mung bean was examined. Maximum shoot length and shoot weight were observed on okra when frutan and urea were used @ 0.1% w/w in combination with pneumatophore and leaves powder whereas urea used @ 0.1% w/w in combination with leaves on mung bean plants. Urea and frutan used @ 0.1% w/w in combination with stem and pneumatophore powder showed maximum root length and weight on okra and mung bean plants. Significant suppression of Rhizoctonia solani was observed when DAP was used @ 0.1% w/w with stem and frutan @ 0.1% w/w with pneumatophore powder on mung bean plants whereas all fertilizers with all parts of A. marina showed complete suppression of R. solani on okra. There was complete suppression of Macrophomina phaseolina when urea and DAP were used @ 0.01 and 0.1% w/w with A. marina leaves powder on okra. All fertilizers and all parts of A. marina showed significant suppression of root infecting fungi on mung bean and okra.
