Abstract:
Field experiment was conducted to study the effect of pre-harvest spray of insecticides and botanicals for control of field infestation of pulse beetle in mung bean at Post Graduate Institute Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, during kharif 2020 and summer 2021. The experiment was laid out in Factorial RBD comprising of four treatments of pre-harvest sprays of insecticides and botanicals and two varieties of mung bean (Phule Vaibhav and BM 2003-2). Seed yield (kg plot^-1) and seed yield (q ha^-1) are differed significantly due to pre- harvest spray of insecticides. The highest seed yield (kg plot^-1) and seed yield (q ha^-1) were recorded in treatment Emamectine Benzoate@ 0.3 ml/L followed by Neemazal @ 4 ml/L. In case of varieties highest seed yield (kg plot^-1) and seed yield (q ha^-1) were recorded in Phule Vaibhav as compared BM 2003-2. In interaction effect highest seed yield (kg plot^-1) and seed yield (q ha^-1) were recorded in pre-harvest spraying of Emamectine Benzoate@ 0.3 ml/L for Phule Vaibhav variety at 50% pod maturity and at maturity stage spraying.
