Effect of Pre-harvest Sprays of Insecticides/Botanicals for Control of Pulse Beetle Infestation and Seed Weight Loss in Mung Bean during Storage

Abstract

Field-cum-laboratory experiment was conducted to study the effect of pre-harvest spray of insecticides and botanicals for control of pulse beetle in mung bean at Seed Technology Research Unit, Mahatma Phule Krishi Vidyapeeth, Rahuri, during kharif 2020 and summer 2021 with four treatments of pre-harvest spray of insecticides and botanicals and two genotypes of mung bean (Phule Vaibhav and BM 2003-2). The results noticed that, pulse beetle infestation and seed weight loss differed significantly due to pre- harvest spray of insecticides. The lowest number of pulse beetle infestation (%) and seed weight loss (%) were recorded in treatment Emamectine Benzoate@ 0.3 ml/L followed by Neemazal 10000 ppm @ 4 ml/L. In case of genotypes lower number of Pulse beetle infestation and seed weight loss were recorded in Phule Vaibhav as compared BM 2003-2. Among the interaction effect significantly lowest pulse beetle infestation as well as seed weight loss was observed with pre-harvest spraying of Emamectine Benzoate@ 0.3 ml/L in Phule Vaibhav to check the infestation of pulse beetle during storage up to 270 day.
