Numerous fungal
pathogens attack loquat. The major disease in Florida is called fire
blight (Erwinia amylovora),
it kills branches and trees in the U.S. Treatment of fire blight
includes removal (pruning) and disposal of affected branches and
application of fungicides. Excessive nitrogen application increase the
susceptibility of loquat trees to fire blight. Many other minor
diseases have been reported to attack, loquat including Pythophthora
(crown rot), Psuedomonas
eriobtoryae (cankers), scab, Diplodia natalensis
(collar and root rot), and Colletotrichum
gloeosporioides (anthracnose). 1 Fire Blight Caused by Erwinia amylovora
