Abstract

First report of sooty mold of longan (Dimocarpus longan L.) caused by Tripospermum porosporiferum Matsushima and T. variabile Matsushima in Puerto Rico.

Abstract

Surveys of longan diseases conducted in Puerto Rico, in 1999, showed sotty moulds affecting the peduncle and whole fruits of the cultivars Ewai, Biew Kiew and Sri Chompoo in Adjuntas and Cabo Rojo. Symptoms included brown, blackish-brown or black, often crust-like, superficial mycelium. Morphological and pathogenicity tests revealed the pathogens as Tripospermum porosporiferum and T. variabile. This is thought to be the first report of T. porosporiferum and T. variabile causing sooty mould of longan in Puerto Rico.
