Aspergillus flavus incidence in groundnut was noticed in all the locations surveyed. Chitradurga (15.40 %) and Davanagere districts (12.27 %) showed higher incidence of A. flavus during kharif, 2012 and 2013 respectively and Gadag district during rabi/summer 2012-13 and 2013-14. Hence, these places were considered as A. flavus prone areas, while Bagalkot and Belagavi districts showed minimum mean incidence during both the years in kharif 2012 and 2013 and rabi/summer 2012-13 and 2013-14, respectively and these were considered as A. flavus low prevalence area. The A. flavus incidence was observed in all Agriculture Produce Marketing Committee yards (APMC) samples during both the years of survey. Higher incidence of A. flavus was observed in Chitradurga district during 2012, (20.14 %) and in Davanagere district during 2013 (18.75 %). All the surveyed districts were grouped into extremely prone, highly prone, moderately prone and least prone areas for aflatoxin contamination. Chitradurga and Davanagere were grouped under extremely high aflatoxin prone areas (>100 µg/kg) while Bagalkot, Belagavi, Raichur, Gadag, Koppal and Dharwad districts were grouped as least aflatoxin prone areas (<10 µg/kg).
