In vitro studies on efficacy of Pseudomonas spp. for plant growth promoting traits and biocontrol of diseases in tea plants

摘要

Tea is one of the major non-alcoholic beverages in the world. Fungal pathogens are important factor limiting the productivity and quality of tea. There is a major environmental concern in the use of fungicides as they increase toxic level in the tea soil. Plant growth-promoting rhizobacteria (PGPR) are precious bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms. The use of PGPR will be alternative to manage several fungal diseases that occur in tea plants to replace chemical fertilizers. In our present study, a total of 250 bacterial isolates were
