Abstract
The groundnut is particularly valued for its protein content. Groundnuts contain more protein than meat and about two and a half times more than eggs. Aspergillus flavus is a predominant fungus which causes yellow mold of groundnut seedlings. Aspergillus flavus cause extensive economic losses either by destroying the plant or by contaminating peanut kernels with the aflatoxins. Groundnuts grown under drought stress may also be predisposed to subsequent aflatoxin in contamination during harvest, handling, or storage. Pseudomonas fluorescens work as a antagonist and inhibits the pathogenicity of A. flavus on groundnut. P. fluorescens were isolated from garden soil samples and selected for their growth inhibition of A. flavus. In this study, the antifungal activity of Pseudomonas fluorescens against A. flavus in groundnut was examined in laboratory and field trials. Inoculation of Pseudomonas fluorescens on groundnut resulted in significant reduction of seed infection by A. flavus, it also reduces the yellowish black spot from the leaves of groundnut. This results suggest that application of this bacteria is effective in reducing fungal population in groundnut. By the utilization of P. fluorescens as the antagonist of A. flavus, health of the groundnut plant can be maintained. So disease free healthy seeds can be produced and disease propagation can be prevented. Hence this investigation will be eco-friendly and useful in increasing productivity as well as storability of Groundnut seeds
