Ecofriendly Management of Spotted Pod Borer (Maruca

Field experiment on the management of spotted pod borer was laid out in a Randomized Complete Block Design in Gunjanagar, Chitwan during January to July 2012 which included three replications and seven treatments. The treatments and their use were (і) Margosom 5 ml/liter of water, (іі) Derisom 2ml/liter of water, (ііі) Anosom 2 ml/liter of water, (іv) Cow urine fermented botanical mixture in 1:5 ratio with water (v) Lipel 2g/liter of water, (vі) Emamectin benzoate 0.25g/liter of water and (vіі) Untreated control. Emamectin benzoate treated plots (9373g) and Derisom treated plots (8727g) produced the highest weight of pods per plots. Similarly, Emamectin benzoate (5.76%) and Derisom (9.43%) had comparatively the lowest percent of damage pods, but the highest percent of damage was found in control plots (46.80%). The lowest larval population of spotted pod borer was found on Emamectin benzoate (1.0) and Derisom (1.13) sprayed plots. The least number of natural enemies and pollinators were observed in Emamectin benzoate sprayed plots (11.03) followed by Derisom (12.60) throughout the observation period. Control plot (19.40) had the highest number of natural enemies and pollinators followed by Cow urine fermented botanical mixture (14.53), Lipel (14.13), Margosm (13.77) and Anosom (13.63) treated plots respectively. Emamectin benzoate gave the highest net yield (18.45mt/ha) of green pods followed b
