Cotton (Gossypium Spp.) is an important commercial fibre crop of Haryana which occupies 5.76 lakh ha.area with productivity 502 kg/hand and production 14 lakh bales. During the last two decades, cotton leaf curl disease (CLCuD) has been found to be one of the major limiting factors. Therefore, in view of the predominance of CLCuD in Haryana, distribution pattern was studied at farmers ’fields during last four consecutive years i.e. kharif, 2012 to 2015. The data revealed that average per cent disease intensity (PDI) of four years ranged from 0.0 to 25.4. However, highest per cent disease intensity (25.4) was observed in Jind district which is closely followed by 22.6 in Hisar district. In the Nontraditional cotton growing districts i.e. Mohindergarh, Rewari, and Jhajjar, cotton fields were found free from CLCuD. It was also observed that CLCuD appeared in severe form during kharif, 2015 as compared to other years in Haryana.
