Botrytis rot, or gray mold as it is often called, is a serious disease in all strawberry production areas and is a disease of concern in most years. The disease is a problem not only in the field, but also during storage, transit, and marketing of strawberry fruit, due to onset of severe rot as the fruits begin to ripen. Other parts infected by the fungus include leaves, crown, petals, flower stalks, and fruit caps.
Anthracnose is an important disease of strawberry with all parts of the plant (fruit, crowns, leaves, petioles and runners) being susceptible to the disease. Disease control is difficult when environmental conditions are favorable for disease development and if inoculum is present. The disease can be especially destructive to susceptible California strawberry cultivars (e.g. Chandler, Camarosa, Albion) when grown on black plastic.
Diagnostic procedures and treatment of phytopthora crown rot of strawberry are discussed in this factsheet.
This factsheet discusses the symptoms and treatment of powdery mildew in strawberries.
Gnomonia causes leaf blotch and stem-end rot of strawberry. The pathogen typically is introduced on transplant material and can build up in plug facilities and in fruiting fields. It rarely becomes an economic concern.
Common leaf spot of strawberries is described.
This factsheet covers Phomopsis leaf blight, a fungus that causes lesions and defoliation in strawberries.
Anthracnose crown rot is caused by the pathogen Colletotrichum gloeosporioides. This disease can cause significant economic damage to strawberry nursery and fruit production systems, particularly in the southeastern production region. This article highlights the symptoms and signs of the disease, disease cycle, methods for diagnosis and integrated management recommendations.
Leather rot, though occurring rarely in North Carolina, can cause substantial losses of fruit yield. This factsheet covers the identification and control of the disease.
This publication discusses the signs and symptoms as well as management of a variety of strawberry viruses including Strawberry Mild Yellow Edge, Strawberry Mottle Virus and Raspberry Ringspot Virus.
Angular leaf spot is caused by the bacteria Xanthomonas fragariae and occurs frequently in North Carolina and surrounding states. The pathogen is introduced on infected plant material and is difficult to control but economic damage is often low.
This factsheet covers leaf scorch, a fungus that weakens strawberry leaves and plants.
