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).
