Abstract

A field study was conducted at CCS Haryana Agricultural University, Hisar during 2016-17 to evaluate the bio-efficacy and economics of thirteen botanicals insecticides against mustard aphid, Lipaphis erysimi Kalt. of Indian mustard. The per cent aphid reduction over control after seven days of application was found to be maximum (93.2 %) in Dimethoate 30 EC @ 625 ml/ha followed by Azadirachtin 10000 ppm @ 1.0 ml per litre of water (81.6%), Azadirachtin 1500 ppm @ 1.0 ml per litre of water (78.49%), neem oil 3% (76.4%) and neem seed kernel extract (NSKE) 5% (71.4%). The highest BCR (1:7.6) was obtained from treatment Dimethoate 30 EC followed by Azadirachtin 1500 ppm (1:5.4), Azadirachtin 10000 ppm (1:4.1) and NSKE 5% (1:3.1). Therefore, Azadirachtin 1500 ppm @ 1.0 ml per litre of water may be recommended as most economical, and ecofriendly alternative to chemical insecticides for the management of mustard aphid.
