Bio rational management of mustard aphid, (Lipaphis erysimi Kalt.)

Study on bio rational management of mustard aphid was conducted on the Oilseed Farm Kalyanpur, Kanpur during rabi, 2018-19. The research was carried out on mustard variety “Varuna”.Chemical control with Dimethoate 30EC@ 1ml/L followed by its second spray after 15 days was the most effective treatment for reducing mustard aphid but Azadirachtin followed by Verticillium leccani@2g/L after 15 days also showed promising results preceded by Azadirachtin followed by Beauveria bassiana@2g/L after 15 days. The bio rational insecticides along with plant based insecticide Azadirachtin were effective enough in controlling the mustard aphid to a considerable level which are less harmful to the environment as well.
