Abstract
Berry fruits are nutrient-rich foods and proved to be beneficial for human health. High nutraceutical properties of these fruits, in particular, blueberries and raspberries, such with exceptionally high antioxidant levels, fiber, and a low natural sugar content have an important criterion for the marketable value as well. Thus, they are defined as functional foods. Naturally, rapid increases in their production and consumption rates during recent years, therefore, make sense. In the cultivation of these berry crops, satisfactory yields and quality of the produce posed a threat by certain pests in the world. Blueberries and raspberries are also infected with viruses that have been identified as new viruses on top of existing ones as a result of expanding cultivation areas around the world. Incurable plant pathogenic viruses cause major damage to the members of blueberry and raspberry as if serious yield losses and longevity of plantings. This chapter is intended to compile knowledge of pathogenic plant viruses that infect blueberry and raspberry plants. Herein, a review of geographic distribution, importance, symptoms, transmission, detection, and management of these berry viruses are provided for the readers.
