Leaf scorch decline of coconut

Abstract

What is recognised as "leaf scorch decline" of coconut is a disorder the cause of which unknown. It occurs in the Gonapinuwela-Baddegama Elpitiya area, in the southern procince of Ceylon. The most characteristic symptoms of "leaf scorch decline" are a necrosis on the leaves root decay and reduction in nut production. Fusarium spp. and Celindrocarpon sp. appear to be associated with root decay. Present investigations suggest that the disorder is more privelant in areas where the soil affords a physical barrier to root penetration and where the soil is badly drained. This paper gives and account of the work carried to for.
