The experiment was conducted to test efficacy of Bacillus thuringlensis products in comparison with recommended conventional insecticide against sorghum stem borer, Chiloparellus (Swinhoe) at Sorghum Research Unit, Dr. P. D. K. V., Akola. The result revealed significant superiority of Bacillus thurillgiellsis and endosulfan treatments at one to three sprays than untreated control in case of leaf injury. In case of peduncle damage, application of two sprays of Bacillus thuringlensis (@ 1 kg/ha) on 25th and 35th, day was on par with three sprays of both endosufan and Bacillus tirurillgiellsis. Similarly on the basis of grain yield, three sprays of Bt recorded maximum grain yield and it was significantly higher than untreated control and also the treatment viz. one spray of Bacillus thuringlensis or endosulfan.
