- Abstract
The studies on incidence of sugarcane borers were observed in sugarcane from April to February during two crop seasons i.e. 2016-17 and 2017-18 at the four locations of Punjab i.e. Gurdaspur, SBS Nagar, Patiala and Fazilka. The early shoot borer was observed from April to June at all the locations, after which it declined. Correlation coefficients of weather parameters with incidence revealed positive significant correlation with T max and T min whereas it is negative highly significant with RH; and negative and insignificantly correlated with rainfall. At Gurdaspur, the incidence of the top borer varied from 0 to 35.00. At SBS Nagar, incidence first appeared (10.00%) in May 2016, reaching a maximum (45.00%) during September 2017; while at Patiala, the top borer started in June 2016 (15.00%), and reached its maximum during September 2016 (27.50 %). However, no activity of top borer was observed during winter. In case of stalk borer, the incidence was observed from September to February with negligible or no activity during March to August.
