Abstract

Pathogenicity study was carried out on groundnut plants by artificial inoculation of one month old giant culture of three pod rot pathogens (Sclerotium rolfsii, Rhizoctonia bataticola and Fusarium oxysporum) which exhibited interaction effect as individual and in combination. In pathogen alone treatments, the results showed the highest/per cent incidence was recorded with S. rolfsii (28.04 %) and R. bataticola (28.03 %) followed by F. oxysporum (16.25 %). In pathogens combination, maximum pod rot incidence (47.49%) was recorded in S. rolfsii + R. bataticola + F. oxysporum followed by S. rolfsii + R. bataticola (24.46 %) and S. rolfsii + F. oxysporum (23.31 %). The minimum pod rot incidence (19.48%) was recorded in R. bataticola + F. oxysporum.
