Abstract:

A survey was conducted in major groundnut growing areas of Karnataka during kharif 2013 and kharif 2014 to identify hot spots of stem and pod rot of groundnut. A total of 80 different locations of eight districts of Karnataka were covered during the survey. During kharif 2013, the highest stem rot (62.80%) and pod rot (73.67%) was recorded in Chitradurga district followed by Tumkur district which recorded stem rot incidence of 42.59% and pod rot of 40.70%. Least incidence of stem rot (17.19%) was recorded in Koppal district and pod rot (8.33%) in Gadag district. During kharif 2014, highest incidence of stem rot (57.83%) and pod rot (71.63%) was observed in Chitradurga district followed by Tumkur district recorded stem rot (46.09%) and pod rot (48.34%). Least stem rot of (17.23%) and pod rot of (8.58%) was recorded in Koppal district. Among surveyed districts, Chitradurga showed highest mean incidence of stem rot (60.31%) and pod rot (72.65%) followed by Tumkur (44.34% and 44.52%, respectively). Hence, Chitradurga and Tumkur districs were considered as hot spot for stem and pod rot of groundnut in Karnataka. However, the lowest mean incidence was observed in Koppal (stem rot - 17.21% and pod rot - 11.29%) followed by Gadag (stem rot - 17.93% and pod rot - 10.79%) and Kalaburgi (stem rot - 21.31% and pod rot - 18.45%).
