First report of Colletotrichum acutatum sensu lato causing anthracnose on gooseberry fruits in the Czech Republic.
Gooseberry (Ribes uva-crispa) is a commonly grown fruit tree or bush in the Czech Republic. Colletotrichum acutatum, a polyphagous fungal plant pathogen, has been reported causing anthracnose on strawberry in the Czech Republic, and recently it has become an important pathogen on the fruits of apple and tomato. In 2012, anthracnose symptoms were noticed on fruits of gooseberry (locality Pribyslavice, near Brno). The symptoms on fruit surfaces were round, brown, shriveled, sunken spots of 1.2-2.0 cm, with orange conidial masses on the spots. Based on morphological characteristics and pathogenicity tests, the causal agent was identified as Colletotrichum acutatum sensu lato, which was confirmed by PCR assay. This is thought to be the first report of C. acutatum sensu lato on gooseberry fruits in the Czech Republic.
