Diseases caused by the fungus Colletotrichum,
particularly leaf spots, are very common in plant
production nurseries. This pathogen attacks a very
wide range of ornamental, fruit and vegetable
species, causing the disease commonly known as
“anthracnose”. Leaf spot diseases caused by a
range of fungi other than Colletotrichum (e.g.
Elsinoe, Phyllosticta and Phoma species) are
sometimes referred to as “anthracnose” as well. It
can sometimes be difficult to distinguish between
leaf spots caused by Colletotrichum and these other
fungi.
