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
