Abstract : Mangoes with decline symptoms were sampled from Florida, USA, and the most commonly isolated fungi included Alternaria alternata, Cladosporium sp., Colletotrichum gloeosporioides [Glomerella cingulata], Dothiorella dominicana, Fusarium spp., Lasiodiplodia theobromae [Botryodiplodia theobromae], Penicillium sp., Pestalotiopsis sp. and Phomopsis spp. The abundance of isolated species varied according to sample source and date. During artificial inoculation A. alternata, G. cingulata, D. dominicana, B. theobromae and Phomopsis spp. caused all or some decline symptoms which included bud necrosis, tip dieback, gummosis and vascular discoloration. It is concluded that mango decline in Florida is a disease complex involving several different fungi. D. dominicana is reported as a mango pathogen for the first time in the USA.
