Abstract: Field-cum-laboratory experiment was conducted to study the effect of pre-harvest spraying of insecticides for control of pulse beetle (Callosobruchus Sp.) in green gram at Seed Technology Research Unit, Main Pearl Millet Research Station, J.A.U., Jamnagar during Kharif 2015-16 to 2018-19. The experiment was laid out in the randomized block design consisted of 13 treatment combinations involving three replications. Number of exit holes of pulse beetle differed significantly due to pre-harvest spray of insecticides and different spraying schedules. The lowest number of exit holes of pulse beetle were recorded in treatment Profenofos 50 EC @1ml/L (0.67), spraying at 50% & 100% pod maturity followed by spraying Emamectin benzoate 5SG @ 0.3g/L (3.91) at 50% & 100% pod maturity at two months of storage.
