A field experiment was conducted during Kharif season of 2011–2012 at Weed Science Research Center, Parbhani, to study the effect of atrazine as a pre-emergence application on soil microflora and nutrient status of soil when used in sorghum for weed control. The soil samples of 15 cm depth were collected and processed for microbial analysis following the dilution plate technique. The population of bacteria and fungi were determined by the standard pour plate technique using soil extract agar media for bacteria and rose Bengal agar media for fungi. Triplicate plates for each sample and the microbial group were used for microbial population before sowing and after harvest of the sorghum crop. The result showed that there is no detrimental effect of herbicidal (atrazine) application at the recommended dose on soil microflora. The fungal and bacterial population was decreased at harvest with the application of atrazine at 0.50 kg ha−1 as compared to its population with recommended cultural practices.
