Field-cum-laboratory experiment was conducted to study the effect of pre-harvest spray of insecticides for control of pulse beetle in green gram at Entomology farm and department, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif 2017-18 to 2018-2019. The experiment was laid out in the randomized block design (Factorial) consisted of 15 treatment combinations involving two factors with three replications. Adult emergence of pulse beetle differed significantly due to pre-harvest spray of insecticides and different spraying schedules. The lowest number of adult emergence was recorded in treatment indoxacarb 14.5 SC followed by profenofos 50 EC and emamectin benzoate 5 SG. In case of spraying scheduled lower number of adult emergence was recorded in spraying at maturity as compared to others. In interaction effect significantly lowest adult emergence as well as lower number of egg laying, seed damage and higher percentage of seed germination was recorded in pre-harvest spraying of indoxacarb 14.5 SC 0.012 per cent (8 ml/10 litre of water) at pod maturity stage to check the infestation of pulse beetle during storage up to two months.
