Abstract

The influence of Pseudomonas fluorescens on histopathological changes caused by Meloidogyne arenaria in groundnut (Arachis hypogaea L.) cv. Co3 root revealed that M. arenaria caused formation of typical multinucleate giant cell and associated abnormalities. P. fluorescens (seed treatment @ 10g/kg of seed) treated groundnut roots showed necrosis which resisted the nematode infection. The nematode development in the root treated with P. fluorescens was inhibited by reduced and poor development of giant cells.
