In Karnataka Mandya district is one of the important paddy growing area. Mono cropping, faulty cultivation practices with continuous submerged conditions are causing higher pest and disease incidence and leading to lower yield. In this context KrishiVigyana Kendra, Mandya demonstrated integrated pest and disease management practices in 30 farmer’s field. The objectives of the study were to minimize the use of chemical pesticides and to establish the use of eco-friendly management practices. The IPM practice includes blast tolerant variety BR 2855, seed treatment with carbendazim 50 WP @ 2 gram per kg of seeds, recommended dose of fertilizer application, clipping off the tip of paddy seedling before transplanting, release of tricho cards 25/ha, use of pheromone traps 20/ha, need based spray of Kitazin 45 EC @ 1 ml and chloropyriphos 20 EC @ 2 ml per liter of water. The results from the IPM demonstration showed that less leaf blast (14, 10, 12 per cent), stem borer (5.60, 7.50 and 8.80 per cent) incidence in all the three years of study as compared to farmers practices. It also obtained high mean yield (57.46) and B:C ratio (2.45).
