Abstract


A total of six species and one genus of fungi associated with black leaf spot
of Sonneratia apetala Buch. Ham (Kewra); and anthracnose and small leaf spot of
S. caseolaris (L.) Engler (Choila) were isolated following “Tissue planting”
method. The fungi associated with black spot of S. apetala were Aspergillus
fumigatus Fresenius, Colletotrichum lindemuthianum (Sacc. & Magn.) Br. & Cav.,
Pestalotiopsis guepinii (Desm.) Stey. and Phoma betae Frank. Anthracnose of S.
caseolaris showed the association of A. fumigatus and P. guepinii. The fungi
associated with leaf spot of S. caseolaris were Curvularia fallax Boedijn, Fusarium
Link, Penicillium digitatum (Pers.) Sacc. and P. betae. Frequency percentage of
association of P. guepinii was highest (74.10) in black spot of S. apetala whereas
the same fungus showed highest frequency percentage (85.70) in case of
anthracnose of S. caseolaris. Phoma betae showed highest frequency percentage
(60.00) in leaf spot of S. caseolaris. Phoma betae is first time recorded from
Bangladesh.
