Abstract/ Executive Summary:

A species of genus Chalara sharminensis was recorded from dried stem of jute. Conidiophores of C. sharminensis were frequently associated with pycnidia of Diplodina sp. The fungus was tried to isolate following “Tissue planting” method on potato dextrose agar medium. The fungus did not produce any mycelia on the culture medium. This is the first report of the fungal genus from Bangladesh.

Program Area: Pest Management

Commodity: Jute

Objectives:

To identify fungus, a new species of Chalara, Chalara sharminensis sp. Nov.of jute.

Methodology:

Jute (Corchorus capsularis L.) is one of the important cash crops of Bangladesh. Many fungi are associated jute plants and cause diseases of the crop. Recently, a fungus under the genus Chalara was found to be associated with dried stems of jute (Corchorus capsularis L.) as a saprophyte. Morphological characters of the fungus were recorded and compared with characteristics of 131 species and subspe-cies of Chalara so far identified throughout the world. The characteristics of the new fungus were different from those of the previously identified species of Chalara. Conidial width of newly recoded fungus was 8-13 μm which is double the largest conidial width (3-5 μm) of C. schoenoplecti M.K.M. Wong. sp. Nov.
