Colletotrichum fragariae

Colletotrichum fragariae is a fungal plant pathogen infecting strawberries. It is part of the Colletotrichum genus and leads to the disease known as anthracnose. This is typically at the crown of the strawberry, which is why it is often called crown rot. It is also known as the anthracnose crown rot. It is not a well-known fungus, and there are many similar fungi that are related to it. The fungus also infects leaves and is known as leaf spot, which is common among all Colletotrichum. This is not as common in the fragariae, as it is more common in the crown. This fungus is also better at infecting younger strawberries/seedlings. The most common way to control this disease is fungicides that are harmful to the environment. There have been studies done to see if the fungus infects other hosts but other than some weeds, it is very specific to strawberries. The occurrence of this fungus in strawberries fluctuates, and data can be found here. It is one of the more deadly pathogens to the strawberry, as once it is inside and affects the crown, the strawberry is no longer able to reproduce or be consumed.
