Field survey on the incidence of Basal Stem Rot (BSR) disease of coconut was conducted in eleven coastal districts viz., Thiruvallur, Villupuram, Cuddalore, Nagapattinam, Thiruvarur, Thanjavur, Pudukkottai, Ramanathapuram, Tuticorin, Kanyakumari and Chengalpattu and in nine inland districts viz., Madurai, Dindigul, Tiruchirapalli, Karur, Perambalur, Salem, Namakkal, Dharmapuri and Krishnagiri of Tamil Nadu. In Tamil Nadu, the district-wise incidence of BSR disease in coconut ranged from 0.11 to 5.43 per cent with a mean incidence of 2.06 per cent. The incidence of BSR ranged from 1.06 to 5.43 per cent with a mean incidence of 3.64 per cent in the coastal districts of Tamil Nadu. In the inland districts, the incidence of BSR ranged from 0.11 to 2.15 per cent with a mean incidence of 0.30 per cent only
