On-farm research trial on biointensive pest management in basmati rice (Pusa Basmati-1) was conducted during wet season 2006 in farmers participatory mode in Haridwar district of Uttarakhand with three treatments comprising of farmers’ practice (FP), chemical based pest management (CBP) and Integrated pest management (IPM) in four villages having two locations in each village. In case of IPM, the crop suffered less incidence of insect pests viz. stem borer (2.43%), leaf folder (4.2%), grasshopper (2.24%); diseases viz. brown spot (2.47%), sheath blast (7.46%), BLB (2.18%) and false smut (0.74%), in contrast to farmers’ pest management practices in which crop suffered with stem borer (5.14%), leaf folder (7.68%), grass hopper (4.53%); brown spot (7.32%), sheath blast (10.24%), BLB (5.63%) and false smut (6.21%). The yield data of various treatments indicates that the IPM plots recorded highest yield i.e., 4.6 t ha-1 in comparison to FP (3.1 t ha^-1) and CBP (4.4 t ha^-1). The highest cost benefit ratio was recorded in IPM (13.16) followed by CBP (12.92) and FP (2.84). The study revealed the cost effectiveness of integrating non-pesticidal strategies with additional benefits like safety to beneficial organism and reduction in pesticide load to the environment.
