Abstract

Pod rot of groundnut is a complex and economically important disease causing severe damage to groundnut production. The disease being soil borne in nature and symptom expression occurring inside the soil from flowering to pod stage generally escape the notice of the farmers resulting in huge yield losses. Hence, a roving survey was conducted on the incidence of pod rot disease of groundnut during kharif-2017 in major groundnut growing mandals of Chittoor and Anantapur districts in Rayalaseema region of Andhra Pradesh. The mean disease incidence varied from 11.4% to 28.6% in Chittoor district, and from 8.5% to 30.0% in Anantapur districts. Isolation of pathogens associated with the diseased samples revealed the occurrence of Fusarium spp., Rhizoctonia bataticola and Sclerotium rolfsii.
