Abstract: An investigation was carried out to evaluate the crop beneficial bio-agents for reduction of insecticidal residues in vegetables grown soil of Surguja district of Chhattisgarh. One hundred and eighty three soil samples were collected from the fields of vegetable growing farmers of Surguja district where different insecticides were used over years for controlling of insects to reduce the losses due to their infestation. The soil samples were collected during rabi season 2017. From these soil samples two hundred and six crop beneficial insecticide tolerant microbial isolates were collected. These isolates were further characterized with respect to their cultural characteristics and screened for their potentiality of Chlorpyriphos+Cypermethrin degradation. Two hundred and six isolates of crop beneficial microorganism which belong to Rhizobium, PSB, Azotobactor and Azospirillum genus were taken in another study for their insecticide degradation potential under in-vitro conditions. All isolates had shown good growth in their respective culture media containing 3000 ppm Chlorpyriphos+Cypermethrin. With increasing concentration of Chlorpyriphos+Cypermethrin Azospirillum isolates did not show their survivility. However, five isolates of Azotobacter, 5 isolates of Rhizobium and 2 isolates of PSB shown their growth in presence of 15000, 16000 and 20000 ppm of tested insecticides, respectively.
