Abstract
We report the incidence of anthracnose caused by Colletotrichum trifolii on Cullen australasicum, a native Australian legume. Natural infection was observed on plants grown in a genetic resources characterisation experiment at Waite Research Precinct, Adelaide. The affected plants showed wilting of the branches and light brown lesions on the leaves. The characteristic symptom was a bluish black discolouration on the infected leaves and stems. In some plants, the infection spread from the leaves and stems across the entire plant leading to the death of the plant.
