Abstract

Potato (Solanum tuberosum L.) is globally important staple and starchy food crop. However, its productivity is severely constrained by several bacterial diseases, among which brown rot, soft rot, and common scab are considered the most destructive and economically damaging. To assess the prevalence of these diseases, a survey was conducted in potato fields and markets across different districts of Karnataka. Incidence ranged from 12.30 to 39.36 per cent with the highest per cent disease incidence (39.36%) recorded in Bangarpet taluk of Kolar and the lowest (12.30) was recorded in Hosayellapur village of Dharwad district. Taluk-wise, Bangarpet showed the highest mean disease incidence (36.81%) followed by Kolar taluk whereas Gokak taluk in Belagavi had the lowest (14.31%). The mean disease incidence of different districts revealed that, Kolar had the maximum disease incidence of 34.42 per cent followed by Hassan district with 30.95 per cent. Whereas, the lowest was observed in Belagavi with 16.05 per cent. Kolar district had the higher incidence of bacterial diseases due to continuous potato cultivation contaminated surface irrigation and favourable sandy loam soils with moderate temperature and moisture. The presence of multiple pathogens and large-scale tuber movement through markets also increased disease spread.
