To The Study Of Isolation And Identification Of Plant Growth Promoting Pseudomonas Fluorescens Antagonist Effect For Controlling Plant Disease

Abstract

Pseudomonas fluorescens was isolated from the rhizosphere of Roorkee-grown Okra. Only five isolates were chosen for further research based on their morphological, biochemical, and physiological characteristics. All five isolates were identified as Pseudomonas fluorescens from bergey’s manual for the determination of bacteriology. Catalase, urease, amylase and citrate utilisation test all positive in all of the isolates. PFTT4 was identified to be a likely strain for all Plant Growth Promoting exercises like age of IAA, HCN, Ammonia, and phosphate solubilization subsequent to being assessed for their plant development advancing properties. Further, In vitro explores uncovered that PFTT4 diminished the development of phytopathogens like Fusarium solani and extraordinarily further developed seed germination just as all development boundaries like shoot and root length. Furthermore, Pseudomonas sp. PFTT4's plant growth-promoting and antifungal activities put forward to it could be there used because of bio-inoculant agents for Abelmoschus Esculentus.
