ABSTRACT

Survey was conducted to collect the isolates of Actinomycetes in major groundnut growing areas of Andhra Pradesh (10 districts) viz., Anantapuramu, Kadapa, Kurnool, Chittoor, Nellore, Prakasam, Guntur, West Godavari, Vizianagaram and Srikakulam during Kharif, 2016. During the survey, 180 rhizospheric soil samples were collected  and isolated a total number of fifty morphologically different Actinomycetes isolates. Basic identification of Actinomycetes was done by visual observation, general morphology, spore formation, colony morphology including Gram stain and biochemical tests and an earthy odour. The Actinomycetes  isolated were maintained for in vitro antagonistic efficacy against stem rot pathogen Sclerotium rolfsii to identify potential isolates.

Keywords:Ground nut, Biocontrol agents, Sclerotium rolfsii, Rhizosphere.
