Crop loss estimation of yellow stem borer Scirpophaga incertulas (walker) damage on paddy

Abstract

The present experiment on effect of different treatments on crop loss due to yellow stem borer was conducted at ZAHRS, College of Agriculture, Shivamogga 2015. The results suggest that the plots which was sprayed thrice at 15 days after sowing in nursery followed by 15 and 30 days after transplanting (DAT) was considered as best treatment. The lowest yield loss compared to the best treatment was realised with 11.07 per cent in the treatment which was sprayed at 15 and 30 days after transplanting. Finally if there were no spray against stem borer, yield loss may expect up to 87.66 per cent.
