Bio-intensive integrated pest management practices were compared with farmer’s practices at Thandalai and Velliyankundram Villages of Madurai District during 2016-17 and 2017-18 respectively. BIPM practices involved Seed treatment with Pseudomonas fluorescens 10 g/ kg of seed, Bund crop with blackgram/ green gram/redgram, Use of light trap at a rate of 1/ ha, Use of biocontrol agents- T. japonicum and T. chilonis, Foliar spray with NSKE 5 % and use of green label pesticides Chlorantraniliprole 18.5% SC 150 ml/ha. The farmer’s practices comprised the applications of chemical insecticides. The mean leaffolder damage was minimum (5.7 and 3.2 percent) in BIPM treatment than farmer’s practices (16.9 and 20.6%) during 2016-17 and 2017-18 respectively. Significantly less dead heart incidence was observed in BIPM treatment (5.2% and 4.7%). Similarly, the mean incidence of white earheads was minimum in BIPM treatment (2.0 and 0.70 during 2016-17 and 2017-18). Highest grain yield was recorded in BIPM treatment (51.72 and 73.50 q/ha). The demonstration of BIPM module gave higher net return and B: C ratio of Rs. 49460/ ha and 1.97 during 2016-17 and of Rs.68337/ ha and 2.18 during 2017-18. Reduction in number of pesticide sprays (From 5- 2) scored highest adoption percentage (66.7%) in rice production technology followed by use of botanical insecticides neem oil/ NSKE 5 % (58.3%).
