Exploring Western Ghats microbial diversity for antagonistic microorganisms against fungal phytopathogens of pepper and chickpea

Newly isolated microbial cultures from Western Ghat soil samples of Kerala region in India were screened for antagonistic activity by well diffusion and dual culture plating against Phytophthora capsici and Rhizoctonia solani, infecting pepper and chickpea, respectively. Bioactive samples were made by varying solvent extraction of the culture broths of the potent isolates belongs to Actinomycetes, Pseudomonas, Bacillus and Trichoderma. The efficacy of the isolates to produce other potent antifungal metabolites such as cell wall degrading enzymes, HCN and volatile compounds were also checked. Treatment with antagonistic isolates in vivo under greenhouse conditions revealed significant reduction of the disease intensity of foot rot disease of black pepper and collar rot of chick pea

Technical Bulletin : BIOFERTILIZER TECHNOLOGY FOR VEGETABLE CROPS

Not AvailableEfficient N, P and K biofertilizer microorganisms were isolated from Kerala soils. The compatibility of these N, P and K biofertilizer microorganisms were studied and the most compatible organisms were selected. They include two nitrogen fixers (Azotobacter chroococcum, Azospirillum lipoferum), a phosphate solubilizing bacterium (Bacillus megaterium) and a potassium solubilizing bacterium (Bacillus sporothermodurans). In order to reduce the cost of production, a new medium (PGPR medium) was developed for the mass multiplication of these microorganisms. The technology for mass multiplication was standardized. Currently talc-based formulation of PGPR Mix – I is being produced for distribution to farmers throughout Kerala. When single inoculant biofertilizer technology give yield increase of 10 percent, PGPR Mix – I is found to give yield increase of 20 - 25 percent depending on the crop.Not Availabl
