Abstract
Plants affected by root infecting pathogens Support a higher rhizosphere mlcrobial pathogens than healthy ones. It was noticed that the total microbial population in the rizosphere was much hinder than that of the corresponding control soil, This increased population is attributed to the presence of root exu-dates and sloughed-off (issues in the rhizosphere. The data also revealed that soil environment itself will be having some influence on the rhizosphere popula tion during; different seasons of the year. There were variations in the microbial populations in different regions of the root. Young and growing regions of the roots were found to harbour more microorganisms, Which is believed to be due to various root secretions. . It is therefore suspected from the present Investigation that higher population of fungi anil bacteria associated with the root system of coconut palms may have some bearing on the incidence of the root (wilt) disease.
