Abstract
Mango (Mangifera indica) is one of the most important import fruit of Saudi Arabia. Brown black rots were found as a post harvest disease on the mango fruit. On the basis of the morphological characters, the fungus causing this disease was identified as Pestalotiopsis mangiferae (Henn). The disease was tested with the Kochs postulates. This is the first report of fruit rots caused by P. mangiferae (Henn) as a post harvest disease in Saudi Arabia.
