Microbial inoculants or Bioinoculants can prompt systemic acquired resistance (SAR) of harvest species to some common crop diseases. So far SAR has been exhibited for powdery mildew, take-all, leaf spot, and root rot. The different types of bio-inoculants are Rhizobacterial inoculants (Nitrogen-fixing bacteria and Phosphate-solubilizing bacteria), fungal inoculants, and composite inoculants. The impact of bio-inoculants on plants was assessed on the basis of physical and biochemical parameters. Peer-reviewed Journal of Biofertilizers & Biopesticides is an important and reliable source of current information on developments in the field. It publishes original papers, reviewed papers, case studies and short communications on the fundamentals, theoretical as well as applications and management of the environment. Open access refers to the unrestricted access to peer-reviewed scholarly research. Bio-fertilizer is a substance used to increase the fertility of the soil. It contains micro-organisms which help the soil to gain its nutrient back and make the soil available for cultivation. Bio-fertilizer don’t make any kind of pollution, so it is not a threat to use them in the place of the chemical fertilizers which causes a lot of pollution to the environment.
