Management of Groundnut Root Rot Disease Caused by Macrophomina phaseolina With Pseudomonas fluorescens

Pseudomonas jluorescens strain Pf 1, effectively inhibited the mycelial growth of Macrophomina phaseolina, the pathogen causing dry root rot in groundnut. Application of Pf 1 as seed treatment (10 g/kg seed) followed by soil application (2.5 kg/ha) against root rot, effectively supported higher plant growth, better native nodulation and grain yield. Sclerotial number and root rot incidence were also greatly reduced.
