A note on the new Hosts of Botryodiplodia theobromae in Pakistan
Syed Ehteshmul Haque and Abdul Ghaffar
ABSTRACT
During a survey of cultivated fields of Malir, Karachi, Annona squamosa L.,
Pithecellobium dulce (Roxb.) Benth and Aralia sp. were found to show symptoms of die
back disease. Microscopic examination of the dead branches revealed the presence of dark
black pycnidia which were ostiolate, measuring upto 3-4.4 mm, with pycniospores dark,
bicelled, ovoid to elongate, measuring 20-27.5 um x 10-15 um. The fungus was
identified as Botryodiplodia theobromae Pat. There does not appear to be any previous
record of B. theobromae Pat, on A. squamosa (KUMH 2179), Aralia sp. (KUMH 2180)
and P. dulce (KUMH 2178) in Fungi of Pakistan (Mirza & Qureshi, 1978) and Fungi of
Karachi (Ghaffar & Kafi, 1968; Ghaffar et al., 1971; Ghaffar & Abbas, 1972). The
specimens have been deposited at the Karachi University Mycological Herbarium.
