The influence of selected insecticides, monocrotophos, cypermethrin and fungicides mancozeb and hexaconazole was evaluated on Azospirillum population in vertisol soils collected from cotton grown fields of Kurnool district, Andhra Pradesh, India. The influence of these pesticides on Azospirillum population was dose dependent; insecticide monocrotophos showed the maximum stimulation towards Azospirillum population at 5.0 kg ha-1, whereas cypermethrin showed maximum enhancement at 2.5 kg ha-1 level. Likewise the fungicide mancozeb and hexaconazole showed maximum stimulation at 5.0 kg ha-1. The pesticides up to 5.0 kg ha-1 were either stimulatory or innocuous to bacterial population. The highest stimulation in bacterial population was observed at 10-day incubation.
