Biological control, an eco-friendly and cost effective approach for plant disease management in agriculture has been practiced for several decades. Pseudomonas fluorescens, one such biocontrol agent is used to combat many phytopathogens. For commercial use, microbial inoculum should be supported by an appropriate formulation preventing a rapid decline of introduced...

Gerbera, a commercial cut flower crop, has widespread acceptance in the international market due to its vibrant colours, shapes, excellent vase life and handling quality. One of the major limiting factors which reduce the commercial value of the crop is the incidence of diseases. Hence, the present investigation was undertaken to identify the fungal diseases of ger...

Pseudomonas spp. are one among the most extensively used biocontrol agent in plant disease management to control foliar, soil borne or seed borne pathogens. However, prevalence of abiotic stresses such as drought, high temperature, salinity and acidity may affect the field performance due to poor survival under adverse conditions. To date, very little effort has...

Trichoderma spp, one of the widely exploited biocontrol agents in the arena of crop disease management, are known for promoting growth and inducing abiotic stress tolerance in plants. However, direct application in the field limits their efficiency due to several adverse factors. Hence, they should be adequately formulated to escalate the efficacy in field appli...

The pathogen causing bacterial wilt of ginger was isolated and identified as Ralstonia solanacearum biovar III based on its cultural, morphological and biochemical characters coupled with pathogenicity. Rhizosphere microflora of ginger from different locations of Thrissur, Waynad and Palakkad districts were isolated. Altogether, 163 rhizobacterial isolates were sel...
