Occurrence and prevalence of diseases of mango was studied in five nurseries located at
Dhaka and Manikgonj during January to October, 2007. Altogether six diseases were
recorded during the survey. The diseases, in order of prevalence (Incidence and Severity)
were Anthracnose (51.14% and 37.39%), Alternaria leaf spot (47.14% and 32.55%),
Powdery mildew (33.30% and 26.03%), Red rust (24.05% and 13.05%), Sooty mould
(10.50% and ) 0.95%) and Bacterial leaf spot (9.75% and 10.12%). Three" fungi-
Colletotrichum gloeosporioides, Alternaria alternaae and Oidium mangiferae and an algaCephaleuros
virescencs were identified from Anthracnose, Altermaria leaf spot and Powdery
mildew and Red rust infected leaves respectively. However, Sooty mould and Bacterial leaf
spot were recorded only on the basis of symptoms observed. The prevalence of the recorded
six diseases varied to each other with respect to nursery and its location. Positive correlation
was observed between prevalence of Anthracnose and Alternaria leaf spot with temperature
and relative humidity. The highest prevalence of Anthracnose and Alternaria leaf spot was
observed in October and lowest in January. Negative correlation was observed between
prevalence of Red rust and incidence of Powdery mildew. The highest prevalence of Red
rust and Powdery mildew was in the month of March, but the disease was observed in
October. Report on Alternaria leaf spot first of its kind in mango seedling in the country. |
