Postbloom fruit drop (PFD) appeared in Florida in 1983 and has since become widespread in the state. The disease appears as necrotic spots on petals and produces fruit drop and the formation of persistent buttons. PFD is caused by the slow-growing orange (SGO) strain of Colletotrichum gloeosporioides which is readily distinguished pathologically, morphologically and physiologically from the common, saprophytic fast-growing grey strain.
