Pest management strategy for rain-fed upland rice in coastal Orissa Rath P. C., Dani R. C. Crop Protection Division, Central Rice Research Institute, Cuttack, Orissa, India Abstract Field trials were conducted for insect pest management in upland rice during wet seasons of 2007 and 2008 at Farm Science Centre, Santhapur, Cuttack, Orissa. Two varieties i.e. one high yielding variety (HYV), Anjali and a local check, Kolia and two management practice viz., schedule based protection (seed treatment with carbendazim (Bavistin) 2 gm/kg seed, herbicide pretilachlor (Rifit) 50EC @ 800 g a.i. ha−1 at 6 days after sowing and monocrotophos 36EC @ 500g a.i. ha−1 at 30 days after germination), need based protection(seed treatment with chlorpyriphos 20EC @ 3.75 lit 100kg−1 seed and application of monocrotophos 36EC @ 500 ga.i. ha−1 on pest infestation) and no protection (farmer practice as control) were compared for insect pest management and grain yield in upland rice ecosystem. During both the years, Anjali recorded the highest grain yield of 3.75 t ha−1 (2007) and 3.69 t ha−1 (2008) under need based protection. Similarly, Kolia under need based protection recorded higher grain yield of 2.36 t ha−1 (2007) and 2.76 t ha−1 (2008) than other treatments. Under all the protection, practices tested the variety, Anjali performed better than the check variety, Kolia in controlling pests like stem borer, termite and gundhi bug.
