Isolation of <i>Pseudomonas fluorescens</i> Species from Rhizospheric Soil of Healthy Faba Bean and Assessed Their Antagonistic Activity Against <i>Botrytis fabae</i> (Chocolate Spot Diseases)

Abstract

Crop protection is an important area of agriculture which needs attention because of most of the hazardous inputs added into the agricultural system are in the form of chemicals. Production of the crop is, however, constrained by several disease infections including fungal diseases. The present study, was isolate twelve <i>Pseudomonas fluorescens</i> isolates from rhizospheric soil of faba bean and were tested for their antagonistic activity against <i>Botrytis fabae</i> that is known to attack faba bean crops. All <i>Pseudomonas fluorescens</i> isolates are shown successfully employed in controlling chocolate spot diseases of plant. <i>Pseudomonas fluorescens</i> isolates 10 (88.1%) showed highest antagonistic activity against <i>Botrytis fabae</i>. All isolate of <i>Pseudomonas fluorescens</i> are indicated successfully employed in controlling chocolate spot diseases of plant due to their antifungal metabolites. Therefore, these isolates can be used as potential of biocontrol agents.
