A roving survey was conducted for three consecutive years during kharif, 2022-23, kharif, 2023-24 and kharif, 2024-25 in major chilli growing areas of Telangana in five districts namely Warangal, Khammam, Mahabubabad, Badradri kothagudem and Hanamkonda covering 48 mandals and 87 villages.  The study revealed variations in per cent disease incidence in the fields surveyed.
