Abstract

A field experiment was conducted at Agricultural Research Station, Anand Agricultural University, Derol, Gujarat, India during kharif, 2018-19, 2019-20 and 2020-21, to study efficacy of different botanicals against Blue butterfly, Lempides boeticus in pigeonpea. Ten treatments including untreated control were evaluated for the management of L. boeticus. The botanicals neem seed kernel extract 5 per cent, neem leaf extract 10 per cent, neem oil 0.5 per cent, custard apple leaf extract 10 per cent, custard apple seed extract 5 per cent, garlic extract 5 per cent, tobacco decoction 2 per cent, eucalyptus leaf extract 10 per cent, azadirachtin 0.15 EC 0.0006 per cent were applied at initiation of pest and subsequent two sprays were applied at ten days interval. Among all the different botanicals, larval population of L. boeticus was found significantly lower in the plot treated with azadirachtin 0.15 EC @ 0.0006 per cent (0.34 larva/plant) followed by neem oil 0.5 per cent (0.45 larva/plant).
