Efficacy of plant growth promoting rhizobacteria (PGPR) Bacillus vallismortis strain EXTN-1 has been proved in eliciting induced systemic resistance (ISR) in several crops. The present paper described the beneficial effects of EXTN-1 in potato as increase in yield and chlorophyll content, and plant protection against Potato Virus Y and X(PVY and PVX). EXTN-1 induced systemic resistance to the plants resulting in significant disease suppression in the field. Also the plants under treatment with EXTN-1 had higher chlorophyll content.
