SEEDLING DISEASES OF MANGO IN FOUR DISTRICTS OF BANGLADESH (Pages : 55 - 61)

Occurrence and prevalence of mango disease was studied in eight nurseries located at Dhaka, Gazipur, Barisal and Khagrachari district during July 2010 to April 2012 and three diseases were recorded during survey. The fungi anthracnose (Colletotrichum gloeosporioides) and leaf spot (Pestalotiopsis mangiferae) were identified firstly by symptoms observed and then confirmed by observing under compound microscope from infected leaves while sooty mould (Capnodium roseum) was identified only on basis of symptoms observed. Conidia of Colletotrichum gloeosporioides were dark coloured, single cell barrel shaped. Conidia of Pestalotiopsis mangiferae had three thick-walled, brownish, non-colors median cells and thin-walled hyaline apical and basal cells, fusiform and straight to slightly curve. Patches on leaf by forming a thin membranous covering over the affected parts was found on the sooty mold affected mango. Maximum incidence and severity of anthracnose and leaf spot was found at Khagrachari district and during the month of October respectively while maximum incidence of the sooty mold was found in January and Khagrachari district.
