EFFECT OF BRADYRHIZOBIUM JAPONICUM AND FUNGICIDES IN THE CONTROL OF ROOT ROT DISEASE OF SOYBEAN
SYED EHTESHAMUL- HAQUE AND ABDUL GHAFFAR
Abstract
Seed dressing of soybean with Bradyrhizobium japonicum alone or mixed with different concentration of fungicides viz., benlate, dithane, bavistin and vitavax showed significant (p < 0.001) protection of roots from infection of Macrophomina phaseolina, Rhizoctonia solani and Fusarium spp. Use of B.japonicum with benlate or bavistin against Fusarium spp., and M.phaseolina and with dithane against Fusarium spp., were more effective than their separate use. B.japonicum used with bavistin (@ 2500 a.i.) showed highest number of nodules per plant. Plant height increased over untreated control where seeds were treated with B.japonicum, benlate, bavistin or dithane or fungicides mixed with B.japonicum.
