Abstract
The aim of this study was to investigate the impact of some pesticides on the plant growth promoting activities of Rhizobium spp. isolated from Sesbania bispinosa. Sustainability and environmental safety of agricultural production relies on eco-friendly approaches like use of biofertilizers, biopesticides and crop residue return. The plant growth promoters (PGP) emphasize the need for further strengthening the research and their use in modern agriculture. PGPs inhabit the rhizosphere for nutrients from plant root exudates. On return, they help to increase plant growth through soil nutrient enrichment by nitrogen fixation, phosphate solubilization, siderophore and phytohormone production, etc. Using pesticide/insecticide in the field may protect the plants from undesirable organisms, however, if accumulated in the habitat may adversely affect the growth and development of non-target lives like the rhizobacteria. The present study was performed to demonstrate the influence of pesticides on plant growth promoting activities of rhizobial isolates from Sesbania bispinosa known as green manure among farmers of Bangladesh. It was observed that two pesticides/insecticides (Imitaf 20SL and Tilt 250EC) in vitro shows variable effect on the plant growth promoting activities of the rhizobial isolates.
