Black spots on your raspberries are just dead or decaying areas of the berry most likely caused by a fungal or bacterial infection. Aphids and other insects, as well as nematodes, spread raspberry plant viruses including tomato ringspot, raspberry mosaic, tobacco streak, calico and bushy dwarf virus. 'Canby', 'Chilliwack', 'Comox', 'Nootka', and 'Skeena' are resistant to the vector aphid's colonization. The raspberry bushy dwarf virus infects both red and black raspberries, resulting in declining vigor and plant yield. Anthracnose and cane blight fungi breed in canes and survive through the winter. Raspberry leaf curl virus is transmitted by the small raspberry aphid (Aphis rubicola). Fields typically are in production for three or four growing seasons before they succumb to disease and no longer remain profitable. Apply a thin layer of petroleum jelly or antibiotic ointment. There are no cures for viral diseases such as mosaic once a plant is infected. Management If ToRSV has been confirmed, remove infected bushes. Several viruses are spread by aphids. Requirements Raspberry plants grow best in regions with cool summers and relatively mild winters.

Downy mildew arises from infected roots and shoots, and it, along with powdery mildew, affects raspberry plant leaves. Reduced plant growth and leaf patterns may also occur. Symptoms Crumbly fruit is characterized by the abortion of many drupelets which causes the fruit to crumble at harvest, resulting in significant reductions of yield and fruit quality. Treatment. Thornless raspberries grow relatively quickly when they are unaffected by disease or fungal infection. These are the most critical periods for controlling aphid vectors. These viruses affect both the canes and the leaves, and they may also be transmitted when infected plants are planted near healthy ones. It can be detected serologically or by RT-PCR.. Tomato ringspot virus is not common but can be very damaging when it infects raspberry. Small raspberry aphid (Aphis rubicola) is a vector of raspberry leaf curl virus. There is no treatment for the virus itself. Plant Disease 102:938-947. Weeds (e.g., dandelion, chickweed and narrow-leaved plantain) can act as reservoir hosts for the virus.

The most common problem is raspberry mosaic disease, caused by a combination of viruses spread by aphids. Of the common diseases that affect raspberry plants, only powder mildew, downy mildew and purple blotch are treatable with chemicals. Infection occurs on different plant parts for each disease. They can infect pruning wounds and other damage sites on raspberry canes. The dagger nematode is the vector for the disease raspberry ringspot caused by the Tomato ringspot virus. infection occurs on primocanes near the end of the growing season. Raspberry viruses are virus diseases affecting raspberries and ocassionally other cane fruit such as blackberries and hybrid berries. Because raspberry bushy dwarf virus is primarily pollen-transmitted, it may be difficult to know if your raspberries are infected before the fruit signs of raspberry bushy dwarf disease appear. This virus is vectored nonpersistently by the large raspberry aphid and the green peach aphid. The impact of this new aphid biotype is yet to be seen, but it is expected to be more important in Washington than Oregon. Verticillium wilt and phytophthora root rot cause leaves to turn yellow and wilt before canes start dying, and plants affected with amellaria root rot die suddenly.

Soil, seed, starter pots and containers can be infected and pass the virus to the plant. Common Disease or Fungus in Thornless Raspberry Plants. Pollenborne viruses include Raspberry bushy dwarf virus and Strawberry necrotic shock virus(SNSV). Ringspot symptoms vary from mottled, chlorotic, mosaic leaves to leaf curling and ring spotting. The only treatment for other fungal diseases, as well as viral and bacterial diseases, consists of pruning away infected canes and leaves, destroying and removing severely affected plants and being sure not to plant new vines in affected soil. Treatment Of the common diseases that affect raspberry plants, only powder mildew, downy mildew and purple blotch are treatable with chemicals. Bacteria of the Agrobacterum genus dwell in the soil and cause crown gall when they are spread to raspberry plants through splashing water and infected pruning tools. Blueberry Shoestring Virus. Oregon State University. Before replanting, test soil for the presence of dagger Leaf symptoms can be varied but typically consist of angular, yellow areas between the veins. Probiotics. Black raspberry necrosis virus is symptomless in red raspberry but in mixed infections with other viruses leads to increased disease severity. Although immunity to some isolates of the virus is reported in some raspberry cultivars, such cultivars are susceptible to other virus isolates (Jones et al., 1989). Plant Disease 97:169-182.

It has not been observed in blackberry in the PNW, even in fields where blackberries were planted and which had severely declining red raspberry that was infected with Tomato ringspot virus. Viruses and virus diseases of Rubus. Aphids may also cause the petioles of leaves to twist and curl when they feed on them. Plant viruses require an agent known as a vector to introduce them into the plant – most raspberry viruses have aphids (greenfly) or soil-dwelling nematodes (eelworms) as their vectors. Plant immune or resistant cultivars if available. Cuttings or divisions from infected plants will also carry the virus. DeMerceau graduated from Columbia University with a Bachelor of Arts in history. RLMV is considered the most wide spread virus on raspberry in the PNW.
