Abstract: The experiment on the bioefficacy of six insecticidal treatments comprising Dimethoate 20% + Cypermethrin 3% EC at four different doses viz., 114.8, 123.6, 132.5 and 141.3 g a.i./ha along with single dose of Dimethoate 30% EC (200g a.i./ ha) and Cypermethrin 25% EC (50 g a.i./ ha) against shoot and fruit borer, Leucinodes orbonalis was conducted at I.G.K.V., Raipur during Rabi 2017-18 and 2018-19. Based on the two spray, it is concluded that the application of T4, Dimethoate 20% + Cypermethrin 3% EC @ 141.3 g a.i./ha found to be the most effective treatment. It was followed by T3, Dimethoate 20% + Cypermethrin 3% EC @ 132.5 g a.i./ha in terms of fruit infestation per cent due to shoot and fruit borer, Leucinodes orbonalis and also recorded higher marketable yield.
