Phomopsis javanica is a species of fungus in the family Diaporthaceae. It is a plant pathogen that affects a variety of crop species, particularly in tropical and subtropical regions.

Taxonomy

The species was first described in 1913 by mycologist Ferdinand Theissen. The genus Phomopsis is characterized by its small, flask-shaped fruiting bodies known as pycnidia, and Phomopsis javanica is no exception.

Distribution and habitat

Phomopsis javanica is found worldwide, but is particularly prevalent in tropical and subtropical regions. It is a common pathogen in agricultural systems, affecting a variety of crop species.

Pathology

As a plant pathogen, Phomopsis javanica causes a variety of diseases in its host plants. These include leaf spot, canker, and dieback. The fungus infects the plant through wounds or natural openings, and then colonizes the plant tissue, causing disease symptoms.

Management

Management of Phomopsis javanica involves a combination of cultural practices, chemical control, and biological control. Cultural practices include crop rotation and the removal of infected plant material. Chemical control involves the use of fungicides, while biological control involves the use of biocontrol agents such as Trichoderma species.
