In evaluation studyten treatments were tested against pod fly, Melanagromyza obtuse. on pigeonpea. The result revealed that treatment Deltamethrin 1 EC + Triazophos 35 EC emerged as the most effective treatment against M. obtusa in minimizing the damage to green and drypods as well as grains. Thiaclopride 21.7 SC and Profenophos 50 EC were found significantly effective in minimizing the cumulative mean per cent infestation of pod flyof pigeonpea.
