“EFFECT OF ARBUSCULAR MYCORRHIZAL FUNGUS, ACAULOSPORA LACUNOSA ON GROWTH OF GROUNDNUT DISEASE CAUSED BY CERCOSPORA ARACHIDICOLA”

Efficacy of arbuscular mycorrhizal fungus (AMF), Acaulospora lacunosa was evaluated for the biological control of soil-borne plant pathogen Cercospora arachidicola in groundnut plant. For this investigation pot culture technique was followed. Soil based mixture of AMF, Acaulospora lacunosa was inoculated onto the root of groundnut plant. In results the colonization by AMF significantly resulted into decreased incidence of disease caused by Cercospora arachidicola. The growth of groundnut showed marked increase in the shoot and root length, fresh and dry weight due to AMF colonization.
