Abstract: With incremental implementation of synthetic pesticides in agriculture sectors, non-target rhizosphere microbial communities are affected largely by this that are critical to soil health maintenance. Rhizosphere microbes are well known for their ability to promote plant growth and control of phytopathogens that are capable of causing disease in plants. Hence the objective of work was to evaluate the effects of synthetic pesticide and biopesticide on the rhizospheric microbial community of Oryza

sativa at different concentrations. Two common rhizospheric bacteria isolated from young and healthy roots of Oryza sativa were considered. Azotobacter is a free living nitrogen fixer and Agrobacterium that acts as natural microbial Pesticide for plants and inhibits the growth of pathogenic bacteria.

 

Keywords: Pesticides, Rhizospheric bacteria, Oryza sativa, Azotobacter, Agrobacterium.
