A study on the susceptibility of promising sugarcane varieties to stalk borer, Chilo auricilius Dudgeon with different levels of nitrogen was conducted at PAU, Regional Research Station Gurdaspur during 2010–11 and 2011–12. The pooled data showed that variety CoJ 89 had significantly less (24.53%) incidence as compared to other two varieties i.e. CoH 119 (29.28%) and CoJ 85 (35.15%). The incidence increased from 3.70 to 69.63% with increase in nitrogen level from 0 to 90 kg N/ac. The highest cane yield was obtained from the CoH 119 variety at 60 kg N/ac.
