Abstract

Roving survey was conducted and collected Actinomycetes isolates in major groundnut growing areas ofAndhra Pradesh (10 districts) viz., Anantapuramu, YSR Kadapa, Kurnool, Chittoor, SPSR Nellore, Prakasam,Guntur, West Godavari, Vizianagaram and Srikakulam during Kharif, 2016. During the survey, 180rhizospheric soil samples were collected and isolated a total number of fifty morphologically differentActinomycetes isolates. Basic identification of Actinomycetes was done by visual observation,generalmorphology, spore formation, colony morphology, an earthy odouri and including Gram stain. The isolateswere characterized based on different biochemical tests. The enzymativ activity of isolates was studied toknow the efficacy against stem rot pathogen Sclerotium rolfsii in groundnut.
