Abstract
Coffee is an important plantation crop in India. Arabica and Robusta coffee are susceptible to fungal disease. Coffee plants propagated through seeds. Rhiozoctonia solani khun is known to cause collar rot/damping off of coffee seedlings in the nursery beds and lead to 10-25 % mortality of seedlings under favourable conditions. For effective management of this disease by bio capsule methods the present study was carried out, ten Rhiozoctonia solani khun isolates were collected from different regions. The pathogenicity effect to produce collar rot symptoms showed that R.s tn 4 is high virulent compared to other isolates during the period of April- June were noticed. In case of bio control agents such as Bacillus subtilis (58.65%) inhibition found to be maximum mean per cent inhibition compared to untreated control (70.50%)
