Among various factors responsible for low yield, losses due to insect-pests attack are of prime importance. Paddy crop is attacked by more than hundred insect species, of which fifteen are of major economic importance. Among these insect-pests, leaf folder, Cnaphalocrosis medinalis Guen is noticed as regular insect-pest at baster plateau zone. Present studies on evaluation of efficacy of indigenous technology against leaf folder. The results revealed that significantly least infestation (3.16%) with the highest grain yield, gross return and CB ratio of 38.32 q/ha, Rs. 50,199.20 and 2.39, respectively recorded in standard check chemical i.e. chlorpyriphos 20 EC. Among the ITK components, Neem had least leaf infestation (9.52%) with highest grain yield (31.52 q/ha), maximum gross return (Rs. 41,291.20) and maximum CB ratio (2.05).Keywords
Leaf Folder, ITK, Grain Yield, Gross Return, CB Ratio.

Studies on estimation of losses caused by rice leaf folder on variety swarna presented regression analysis revealed a non significant negative relation between damaged flag leaves and grain yield in natural infestation (r2 = 0.186) while, a significant negative relation observed in augmented condition (r2 = 0.739).Keywords
