On-farm impact of biocontrol technology against rice stem borer, Scirpophaga incertulas (Walker) and rice leaf folder Cnaphalocrocis medinalis (Guenee) in aromatic rice

Abstract: Field experiments were conducted at farmers' rice fields in Punjab, India during 2009 to 2011 to validate large scale bio-intensive pest management (BIPM) practices in comparison to conventional chemical-based strategies in aromatic rice. The results showed that conventional chemical-based farmers' practices resulted in lower incidence of leaf folder (1.47% damaged leaves) and stem borer (1.07% dead heart, 2.57% white earheads) as compared to the fields with inundative releases of egg parasitoids, wherein the mean per cent incidence of leaf folder (2.77%) and stem borer (1.63% dead heart, 4.07% white earheads) was on higher side. However, the yield data indicated that farmers adopting BIPM practices were able to get similar yield and better cost: benefit (C: B) ratio (42.5 q ha^-1, 1 : 7.37) in comparison to farmers' practice (44.2 q ha^-1, 1 : 6.42). Moreover, in BIPM fields, higher population of natural enemies, like spiders, coccinellids, dragonflies and damselflies were found predating on larval stages of insect pests. Thus, the adoption of BIPM based technology over a long run may provide better monetary and environmental benefits to the stakeholders.
