Abstract

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.
