Mode Of Action:
The Plant Growth Promoting Rhizobacteria (PGPR) colonizing the root surface and closely adhering soil interface, the Rhizospheree. Some of the PGPR can also enter root interior and establish endophytic population. Many of them are able to transfer the endodermis barrier, crossing from the root cortex to vascular system, and subsequently thrive in stem, leaves and tuber and other parts. Consequently intimate association between bacteria and host plant can be formed. Offensive PGPR colonization and defensive retension rhizosphere niche are enabled by production of bacterial allelochemicals, including iron–chelating siderophores, antibiotics, biosidal volatize, lytic enzymes, detoxification enzymes. The PGPR have provided a greater understanding of multiple facets of disease suppression, unique association of non symbiotic endophytic bacteria and apparently a more pronounced growth enhancing effect on host plant
Benefits To The Crop:
PGPR controls wide range of phytopathogenic fungi, bacteria, viruses, nematodes etc. Bio control mechanism which may be due to antibiotics, siderophores and enzymes or by systematic resistance against phytopathogen throughout the entire plant system.
Effective against root rot and stem rot caused by Scelerotinia, Rhizoctonia, Phythium, Phytopthora, Alternaria, Cercospora, Macrophomina diseases etc.
Improving plant stress tolerance to drought, salinity and alkalinity condition.
Production of phytohormones like IAA, GA and Gibberellins.
It improves height and colour for more production
