Author(s): A Padmasri, T Pradeep and B Anil
Abstract: Field-cum-laboratory experiment was conducted to study the effect of pre-harvest spray of insecticides for control of pulse beetle in Redgram at Seed Research and Technology Centre, Prof. Jayashankar Telangana State Agricultural University, Rajendranagar, during Kharif 2016 and 2017. The design used was split plot design consist of five treatments and three spraying schedules with three replications. Adult emergence of pulse beetle and seed damage differed significantly due to pre- harvest spray of insecticides and different spraying schedules. The lowest number of adult emergence were recorded in treatment profenophos 50 EC followed by emamectin benzoate 5 SG and neemazal 10000 ppm. In case of spraying scheduled lower number of adult emergence and seed damage were recorded in spraying at 50% pod maturity and maturity as compared to others. In interaction effect significantly lowest adult emergence as well as seed damage were recorded in pre-harvest spraying of profenophos 50 EC 0.012 (1 ml/ litre of water) at 50% pod maturity and maturity stage to check the infestation of pulse beetle during storage up to two months.
