Anthracnose fruit rot, caused by the fungus Colletotrichum acutatum, is an important disease for strawberry production worldwide. Other species of Colletotrichum, such as C. fragarie and C. gloeosporioides, are less frequently involved in fruit rot. Although fruit rot is the most important symptom caused by C. acutatum, the fungus can also attack other parts of the plant including the crown, leaves, petioles, and roots.

Pomegranate (Punica granatum L.) has primarily been cultivated at home in Florida and other southeastern states. Over the past 15 years, growers, nurseries, researchers, and Extension agents have explored the potential of pomegranate as an alternative fruit crop. Early field trials revealed that pomegranates are highly susceptible to Colletotrichum gloeosporioides, causing severe anthracnose fruit rot and premature fruit drop. The development and use of disease-resistant cultivars are considered some of the best methods to manage this disease. This publication presents our findings from evaluating 35 pomegranate cultivars under natural disease pressure in central Florida and by artificial inoculation. The susceptibility of such pomegranate cultivars varied widely, with six exhibiting resistance to anthracnose fruit rot. More comprehensive research is warranted to further develop anthracnose-resistant cultivars and to enhance our understanding of disease resistance in this crop.

Fungi make up approximately 90% of known plant pathogens. One of the most common fungal diseases of plants is anthracnose. The name anthracnose represents a group of related fungal diseases that affect many different landscape and crop plants. This publication is intended to provide information to professional landscapers, pest control operators, Extension agents, and homeowners on how to recognize and potentially manage anthracnose diseases of landscape plants. It includes 47 images of common plants affected by the disease.
