Online published on 30 November, 2019. Abstract Field trials were conducted to manage powdery mildew of pea caused by Erysiphe pisi var. pisi through bioagents and chemicals during 2010–11 and 2011–12. Results revealed that the most effective treatment for the control of powdery mildew was Karathane foliar spray with disease intensity of 2.0 per cent followed by Sulfex (3.75%). Pant bioagent-3 seed treatment + foliar spray and Pant bioagent-3 foliar spray were also found effective with disease intensity of 6.25 and 11.25 per cent. Disease was maximum (36.25%) in control. Yield was also more in foliar spray with Karathane (52.33 q ha−1) and Sulfex (50.13 q ha−1). Seed treatment + foliar spray with Pant bioagent-3 and foliar spray with Pant bioagent-3 too gave better yield (45.85 & 44.35 q ha−1) as compared to control (35.03 q ha 1). Seed treatment along with foliar spray by Pant bioagent-3 reduced disease intensity and produced good yield over the control and was economical than the chemicals, hence may be recommended for end users.
