PGPR offers an environmentally sustainable approach to crop production and health. Many members of genera pseudomonas sp. perform beneficial effects on plants. Among them P. putida and P. fluorescens are fluorescent pseudomonas that represent Significant part of these Members. The rhizosphere soil was collected from cultivated plots. P. fluorescence was isolated and identified through morphologicaland hemical tests and it was treated against some plant pathogens. The biocontrol potential of P. fluorescens against plant pathogen such as A. terreus sp, Circinella sp, Verticillium sp, was assessed by dual plate technique. The seed treatment was made on four plants namely Hibiscus esculentus, Oryza sativa, Capsicum annum, Spinacia olerace. Pot culture techniques was applied for the growth of plants along with p. fluorescence inoculums (100ml) and chemical fertilizer (10g).The plant height, ischolar_main length, ischolar_main biomass, shoot biomass were also estimated. The results were discussed.

Abstract


PGPR offers an environmentally sustainable approach to crop production and health. Many members of genera pseudomonas sp. perform beneficial effects on plants. Among them P. putida and P. fluorescens are fluorescent pseudomonas that represent Significant part of these Members. The rhizosphere soil was collected from cultivated plots. P. fluorescence was isolated and identified through morphologicaland hemical tests and it was treated against some plant pathogens. The biocontrol potential of P. fluorescens against plant pathogen such as A. terreus sp, Circinella sp, Verticillium sp, was assessed by dual plate technique. The seed treatment was made on four plants namely Hibiscus esculentus, Oryza sativa, Capsicum annum, Spinacia olerace. Pot culture techniques was applied for the growth of plants along with p. fluorescence inoculums (100ml) and chemical fertilizer (10g).The plant height, ischolar_main length, ischolar_main biomass, shoot biomass were also estimated. The results were discussed.
