First report of anthracnose caused by Colletotrichum sichuanensis on Phaseolus lunatus in Brazil.
In 2015, lima bean (Phaseolus lunatus) leaves with typical symptoms of anthracnose were collected in 5 states of northeastern Brazil, including Pernambuco, Paraiba, Piaui, Ceara and Alagoas. The symptoms are characterized by reddish spots on the leaf blade and along the primary and secondary veins, resulting in wrinkled leaves. On pods and stems, the lesions are depressed and reddish with developmental acervuli. The causal pathogen was isolated and identified as Colletotrichum sichuanensis based on morphological, molecular and pathogenicity analyses. This is thought to be the first report of C. sichuanensis in Brazil causing anthracnose in lima bean.
