Evaluation of Pseudomonas fluorescens (Pf-1) against blackgram and sesame root-rot disease.

Abstract

Pseudomonas fluorescens strain Pfl, effectively inhibited the mycelial growth of Macrophomina phaseolina , the pathogen causing dry root-rot in blackgram and sesame. Application of Pf1 as seed treatment (10g / kg seed) followed by soil application (2.5 kg / ha) against root rot effectively supported higher plant growth, better native Rhizobium nodulation and grain yield. Sclerotial number and root rot incidence were also greatly reduced. The rhizosphere soil recorded a higher number of Pf I population.
