Twenty isolates of Pseudomonas sp., were tested for the control of soilborne root-infecting fungi like Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani under laboratory and greenhouse conditions. In dual culture plate assay, strain 78 inhibited all the test fungi. Other Pseudomonas sp., failed to check the radial growth of M. phaseolina whereas isolates 51 and 82 significantly inhibited radial growth of F. solani and R. solani. Three isolates of Pseudomonas sp., (51, 78 and 82) when used as seed dressing or as soil drench showed substantial reduction in root-rot infection caused by M. phaseolina, F. solani and R. solani in mungbean. Strain 78 was found to be most effective in the control of root-infecting fungi. Of the root-infecting fungi, R. solani was most susceptible to Pseudomonas sp. |

The fungal species of rhizosphere of Avicennia marina was studied and results were evaluated in terms of occurrence, distribution and dominance. Species of Aspergillus and Penecillium were found to be more dominent constituents of the rhizosphere mycoflora. The rhizospheres examined revealed the preponderance population of Deuteromycotina and Ascomycotina whereas Mastgomycotina were poorly represented. The results of the study lead us to the conclusion that the mangrove swamp, specially the rhizosphere is a potential habitat for fungal inhabitation. The rhizosphere soils were found to favour the establishment of the fungal community, irrespective of varying salinity levels, perhaps due to their pronounced rhizosphere effects. |
