Bio-intensive pest management of leaf folder and stem borer was demonstrated on basmati rice at village Kami Khera (District Ferozepur), Punjab over 60 hectares during 2002-2005. Bio-intensive management package included one application of cartap hydrochloride, (Padan @ 25 kg/ha) and seven weekly releases of Trichogruimnu cliilonis and T. japonicum @100000/ha each starting from 30 days after transplantation. The mean per cent leaves folded (2.02), dead hearts (3.05), white ears (5.45) and yield (43.99 q/ha) in BPIM were on par with chemical control, (mean per cent leaves folded (1.77), dead hearts (2.62), white ears (4.48) and yield (44.83 q/ha)), and both the treatments were significantly better than control. The cost: benefit ratio was 1:4.01 and 1:4.68 for bio-intensive management practice and chemical control, respectively.
