Description A study was conducted to determine the seedborne nature, disease transmission and eradication of seedborne infection by Rhizoctonia bataticola in groundnut. In case of 10 groundnut accessions, infection percentage of R. bataticola, ranged between 13.3 to 73.3. Component-plating method indicated that the pathogen is located mainly on the seed coat and rarely in the endosperm and embryo. Infection in embryo and endosperm was always associated with seed coal infection. All accessions showed pre-emergence damping-off in the form of seed rot. Post- emergence damping-off was noticed in three accessions. The per cent infection ranged between 9.5 to 42.9 in case of pre-emergence damping-off. while it was 4.8 to 19.1 for post-emergence damping-off. The latent infection of R. bataticola from healthy seedlings was proved using Potato carrot agar medium. Infected seeds of 10 groundnut accessions were gi~own and no apparent symptoms were observed on the plants for one season, but seeds harvested from such plants resulted in seed infection of 6.1 - 33.3 % indicating the seed transmission nature of the pathogen from one generation to the next. Carbendazim + tin ram @ 2g a.i / kg seed can be used as a routine treatment in quarantine laboratories to eliminate R. bataticola from groundnut seeds
