Pseudomonas fluorescens cultures were isolated from rhizosphere of rice cultivated in different locations of Kuttanad. Three effective strains viz., PF 43, PF 46, PF 47 and combined isolates PF 43+PF 46+PF 47 were tested in the farmers plot of nine different locations of Kuttanad against rice sheath blight disease during Rabi 2011-12. The data on disease incidence and severity indicated that the combined isolate was performed well in restricting the disease incidence and severity. The pooled data showed that combined strains of PF 43+46+47 was found most effective against sheath blight disease and thereby increased the grain yield than other single isolates as well as standard fungicide check.Keywords

The compatibility of Pseudomonas fluorescens with 15 fungicides, 9 insecticides and 10 weedicides was tested under laboratory condition. All insecticides, herbicides and 12 fungicides except saaf, kocide (copper hydroxide) and zineb were found to be compatible with P. fluorescens. The study indicated that most of the fungicides, insecticides and weedicides can be mixed with P. fluorescens for use in agriculture.Keywords

Pure cultures of bacterial antagonist, Pseudomonas fluorescens were isolated from different locations in Kuttanad for screening against rice sheath blight disease. Three effective strains, viz., PF43, PF46 and PF47 were tested individually and also in combination against sheath blight under field conditions. Combined application of PF43, PF46 and PF47 was found to be effective for sheath blight disease management during rabi 2009-10, kharif 2010 and rabi 2010-11.Keywords
