Online published on 21 February, 2022. Abstract ICAR- Krishi Vigyan Kendra, Tirunelveli, Tamil Nadu conducted frontline demonstrations on the integrated pest and disease management (IPDM) technology in paddy at Velayuthapuram (DFI) village of Kadaiyanallur block, Tamil Nadu during rabi season 2018. The IPDM technology comprised seed treatment with Pseudomonas fluorescens @ 10 g/kg, soil application of P fluorescens @ 1 kg/acre, seedling root dip of P fluorescens @ 1 kg/acre, foliar application of Lecanicillium lecanii @ 1 l/acre, field release of Trichogramma japonicum @ 2 cc and T chilonis @ 2 cc, installation of stem borer pheromone traps @ 10/acre, installation of yellow sticky traps @ 5/acre and need-based application of neem oil @ 3 per cent. The results revealed that adoption of IPDM practices recorded the lower incidence of stem borer (6.5%), leaf folder (7.3%), gall midge (5.4%) and blast (5.1%) compared to the farmers’ practice. The natural enemies’ population (3-6 number/hill) was also recorded higher in IPDM practices’ fields compared to the famers’ practice. IPDM demonstration plots recorded a higher yield (5.41 tonnes/ha), net return (Rs 37,040) and benefit-cost ratio (1.87). Top Keywords IPDM, Paddy, Frontline demonstrations, Farmers’ practice. Top |
