Abstract

                                Leaf blight disease caused by Pestalotiopsis palmarum was found both in seedlings and adult coconut palms. Adult palms of 20 to 40 years of age were highly susceptible to the disease. It reduced the height. leaf production and girth at collar of coconut seedlings to the extent of 10.4, 20.1 and 12.5 per cent respectively. The nut yield of coconut palms was decreased by 10 to 24 per cent due to leaf blight incidence.
