Abstract:
A roving survey was conducted in total 16 locations belonging to four mandals of Nellore and Kadapa districts of Andhra Pradesh, for recording the prevalence and distribution of root rot incidence in acid lime caused by various pathogens Fusarium, Rhizoctonia, Phytophthora, Diplodia and Ganoderma. The per cent disease incidence in the surveyed locations was in the range of 2.70 per cent to 11.42 per cent. The root rot disease incidence was found to be high in Rapur mandal (8 per cent) followed by Podalakur mandal (5.8 per cent) of Nellore district. The incidence of root rot diseases was low in Kadapa district (3.59 per cent) comparatively. Among the surveyed locations, most of the plants were infected by dry-root rot disease caused by Fusarium solani.
