The four modules included 2 bio-intensive integrated pest management modules, one farmers practice and untreated control. Module-II (Installation of pheromone trap @ 5 traps/acre for monitoring the population of Leucinodes orbonalis + Six release of egg parasitoid, Trichogramma chilonis @ 1.0 Lakh/ha against Leucinodes orbonalis, initiated with flowering and subsequent at 10 days interval + four sprays of NSKE (5%) at 50, 60, 80 and 90 DAT + one spray of Bt @ 1500 ml/ha at 70 days after transplanting + mechanical clipping of infested shoot at weekly interval+ one spray of chlorantraniliprole 18.5 SC @ 0.3 ml/lit at 100 DAT) had least shoot damage and fruit damage. The highest average fruit yield (302.06 q/ha) was found in Module-II with benefit cost ratio (1:7).
