Diplodia natalensis

Lasiodiplodia theobromae is a plant pathogen with a very wide host range. It causes rotting and dieback in most species it infects. It is a common post harvest fungus disease of citrus known as stem-end rot. It is a cause of bot canker of grapevine. It also infects Biancaea sappan, a species of flowering tree also known as Sappanwood. On rare occasions it has been found to cause fungal keratitis, lesions on nail and subcutaneous tissue. It has been implicated in the widespread mortality of baobab (Adansonia digitata) trees in Southern Africa. A preliminary study found the deaths to have a complex set of causes requiring detailed research.
