In May 2004, fruit rots of balsam pear (Momordica charantia L.) was found in Okinawa Prefecture, Japan. Blackish, powdery and water-soaked lesions were observed on diseased fruits. A Rhizopus species isolated consistently from the diseased fruits was identified as Rhizopus stolonifer var. stolonifer and was demonstrated to cause the disease.
Anthracnose of pitaya (Hylocereus undatus (How.) Britt. & Rose was observed in Okinawa Prefecture in 2002. Numerous conidial masses formed on the surface of water-soaked lesion on fruits. A Colletotrichum species was isolated from the diseased fruits and plants, and typical symptoms were reproduced after inoculation with the isolated fungus. The causal agent was identified as Colletotrichum gloeosporioides
