Biological Control of Early Blight of Tomato (Solanum lycopersicum L.) by the Use of Pseudomonas fluorescens (Flugge and Migula) under Field Condition

Tomato is the second most important vegetable crop. It widely grown on all over world. Diseases are major constraint in economic crop production as they inflict heavy loss tomato. Among various fungal diseases, early blight was reported severe it causes damage to The main aim of this study explore potentiality native and efficient isolate P. fluorescens biocontrol agent. A total 30 Pseudomonas isolates were isolated from soil samples different villages Navsari district by serial dilution method King’s B medium. purified observing under UV light. field experiment conducted for evaluation against diseases treatments fluorescens, treatment T8 i.e. combined use recorded with minimum per cent disease intensity (37.78%) maximum (69.33%) control (T9, water spray).
