abstract
An investigation was carried out during rabi 2017-18 to evaluate the bioefficacy of seven integrated pest management modules against shoot and fruit borer, Leucinodes orbonalis (Guenee) in brinjal. M1-Moderately resistant brinjal genotype selected from screening experiments (IC 136061), M2- Control, M3-M6 comprised of various components from cultural, physical, mechanical, biological and chemical control methods in various combinations, M7-farmers practice. Module-1 consisting moderately resistant genotype received least overall mean per cent shoot infestation (12.98), fruit infestation on number and weight basis (15.05 and14.33), higher B:C ratio (4.05:1) compared to all other modules (M2-M7). However farmers practice M7 recorded with higher marketable fruit yield (32427.73 kg ha^-1), gross returns followed by M6 (26073.60 kg ha^-1), M5 (23654.40 kg ha^-1) M4 (18562.13 kg ha^-1), M3 (17472.00 kg ha^-1) and M2 (14649.60 kg ha^-1) registered with gross returns of Rs.411712.00 ha^-1 (B:C ratio 3.38:1), Rs.312883.20 ha^-1 (B: C ratio of 2.68:1), Rs. 283852.80 ha^-1 (B: C ratio of 2.44:1), Rs.222745.00 ha^-1 (B: C ratio of 2.18:1), Rs.209664.00 ha^-1 (B: C ratio of 2.17:1) and Rs. 175795.00 ha^-1 (B: C ratio of 2.20:1) respectively.
