An experiment was conducted at Adhartal farm, Integrated Farming System unit, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during kharif season 2022-23. Two spraying of brahmastra @ 45ml/L initiating on 21 DOC and repeated at 15 days interval was found to be most effective in reducing whitefly and jassid population and registered higher grain yield and also found to be most economic (1:16.53) followed by brahmastra @ 30ml/L (1:11.95), agniastra @ 45ml/L (1:9.31), agniastra @ 30ml/L (1:5.83), neemastra @ 45ml /L (1:5.39) and neemastra @ 30ml /L (1:3.45). The four biodynamics viz., brahmastra, agniastra, neemastra and dashparni ark were safe for potent predators (Lady bird beetles and spider).
