Mass Production, Formulation, Delivery and Commercialization

  • P. Parvatha Reddy


To ensure the sustained availability of biocontrol agents, mass production technique and formulation development protocols have to be standardized to increase the shelf life of formulation. It facilitates the industries to involve in commercial production of plant growth-promoting rhizobacteria (PGPR). PGPR with a wide scope for commercialization include Pseudomonas fluorescens, P. putida, P. aeruginosa, Bacillus subtilis and other Bacillus spp. The potential PGPR isolates are formulated using different organic and inorganic carriers either through solid or liquid fermentation technologies. They are delivered either through seed treatment, bio-priming, seedling dip, soil application, foliar spray, fruit spray, hive insert, and sucker treatment. Application of PGPR formulations with strain mixtures performs better than individual strains for the management of pest and diseases of crop plants, in addition to plant growth promotion. Supplementation of chitin in the formulation increases the efficacy of antagonists. More than 33 products of PGPR have been registered for commercial use in greenhouse and field in North America. Though PGPR have a potential scope in commercialization, the threat of certain PGPR (P. aeruginosa, P. cepacia and B. cereus) to infect human beings as opportunistic pathogens has to be clarified before large-scale acceptance, registration and adoption of PGPR for pest and disease management.
