Raspberry ringspot virus (RRV) is a plant pathogenic virus that primarily affects raspberries (Rubus spp.), specifically red raspberries, but can also infect blackberries and other related plants. It belongs to the genus Comovirus and family Secoviridae. RRV is primarily transmitted through vegetative propagation, specifically through the use of infected plant material for multiplying plants, but it can also be transmitted by aphids, nematodes, or through contact with infected tools or machinery.
Symptoms of raspberry ringspot virus infection vary depending on the plant species, age, and environmental conditions. In raspberries, infected plants are characterized by the presence of yellow rings on the leaves, which later develop into brown necrotic areas. Infected plants may also exhibit stunted growth, reduced vigor, and decreased fruit production. In some cases, raspberry ringspot virus infection can cause the death of the entire plant.
Prevention and control measures for raspberry ringspot virus include the use of certified virus-free planting material, regular monitoring and removal of infected plants, practicing good sanitation by disinfecting tools and equipment, as well as employing strict aphid and nematode control methods. Crop rotation and proper weed management are also important to reduce the potential for viral spread.
Overall, managing raspberry ringspot virus is crucial for preserving the health and productivity of raspberry plants, ensuring the sustainability of commercial raspberry production, and maintaining the quality of the fruit.
