Plant Growth Promoting Rhizobacteria Formulations and its Scope in Commercialization for the Management of Pests and Diseases

Phosphate solubilization and growth promotion by Pseudomonas fragi CS11RH1 (MTCC 8984), a psychrotolerant bacterium isolated from a high altitude Himalayan rhizosphere

“…The rhizobacteria participate in many key ecosystem processes, such as those involved in plant growth promotion, biological control, nutrient cycling and seedling establishment (Kloepper et al 1992;Weller 2002). The beneficial effect of these rhizobacterial populations can be optimally harvested only when carrier-based formulations that are amenable for field level applications are developed and made available to the clientele (Nakeeran et al 2005). The success of these carrier-based formulations largely depends on the bacterial strain used for inoculant production.…”

Practical use of CMC-amended rhizobial inoculant for <I>Mucuna pruriens</I> cultivation to enhance the growth and protection against <I>Macrophomina phaseolina</I>

“…There was improvement in seed germination percentage and nodule number/plant consequently enhancing the nitrogenase activity. Nakkeeran et al (2005) mentioned that the performance of biocontrol agents in the formulations can be increased by the incorporation of watersoluble adjuvants, oils, stickers and emulsions. Incorporation of CMC in formulations serves as a sticker for uniform seed coating of microbes, allowing better colonization of rhizobia and competitive removal of pathogens leading to enhancement of germination of the seeds.…”

Plant Growth Promoting Rhizobacteria (PGPR): A Bioprotectant bioinoculant for Sustainable Agrobiology. A Review

“…These sites encourages healthy competition among organisms for more competency, saprophytic abilities and potential for enhancing plants growth. In addition, it successful organisms multiply easily through a broad spectrum of actions as a result of high nutrient and carbon source, compete favourably with other microorganisms and poses tolerance to drought (Ngumbi and Kloepper, 2016).Additionally, they show high resistance to environmental stress such as desiccation, heat, oxidative agents, heavy metals and crude oil pollution and UV radiation (Nakkeeran et al, 2005). Since the rhizosphere is very rich in nutrients, it associate bacteria (rhizobacteria) tend to developed a unique means of communication by enabling the effective selection of it mutual partner by creating host specificity and selective sensitive environment where diversity is less (Sivasakthi et al, 2014).…”
