Effects of root-dip treatment with certain phosphate solubilizing microorganisms on the fusarial wilt of tomato.
Root-dip application of Bacillus subtilis, Pseudomonas fluorescens, Aspergillus awamori, Aspergillus niger and Penicillium digitatum resulted in significant decline in the rhizosphere population of Fusarium oxysporum f. sp. lycopersici. A significant decrease in the severity of wilt occurred with A. awamori (37.1%) and P. digitatum (21.3%) compared to the control. Root-dip treatment with the phosphate solubilizing microorganisms tested resulted in significant increase in the yield of tomato, being greatest with A. awamori and P. digitatum in pathogen inoculated (36% and 33%) and uninoculated plants (19% and 23%). A chemical fungicide gave 24% better yield.
