What is the plum dwarf virus and how does it affect apricots?
Plum dwarf virus is a plant virus that primarily affects plum trees but can also infect apricot trees. It is transmitted by aphids, which feed on infected plants and then spread the virus to healthy ones. The virus can cause stunted growth, yellowing of leaves, and reduced fruit production in apricot trees.
| What is Plum Dwarf Virus? | How does it affect apricots? | Prevention and Control |
| Plum Dwarf Virus is a viral disease that primarily affects plum trees. | When apricot trees are infected with Plum Dwarf Virus, they show symptoms such as stunted growth, reduced fruit production, and leaf discoloration. | The best prevention method is to plant virus-free nursery stock and regularly inspect and remove any infected trees. There is no cure for the virus, so prevention is crucial. |
| The virus is transmitted through grafting infected plant material onto healthy trees or by aphids feeding on infected plants. | The virus weakens apricot trees, making them more susceptible to other diseases and pests. | It is important to control aphid populations and practice good sanitation in orchards to reduce the spread of the virus. |
How can you identify if your apricot tree is infected with plum dwarf virus?
Identifying an apricot tree infected with plum dwarf virus can be challenging as symptoms may vary. However, some common signs include stunted growth, distorted leaves, yellowing or reddening of leaves, and reduced fruit size and quality. It is recommended to consult with a professional arborist or horticulturist for accurate diagnosis.
- Stunted Growth: One of the signs of apricot trees infected with plum dwarf virus is stunted growth. The infected trees may be smaller in size compared to healthy trees of the same age.
- Leaf Symptoms: Look for abnormal leaf symptoms on your apricot tree. Infected trees may have curled, distorted, or yellowing leaves. There may also be a reduction in leaf size and overall leaf density.
- Fruit Symptoms: Another indicator of plum dwarf virus infection is the presence of symptoms on the fruit. Infected apricot trees may produce small, misshapen, or deformed fruits. The fruits may also have uneven ripening or show signs of premature dropping.
Can plum dwarf virus be treated in apricot trees?
Unfortunately, there is no cure for plum dwarf virus in apricot trees once they are infected. The best approach is prevention by using disease-free planting material and regularly monitoring and controlling aphid populations. Infected trees should be removed to prevent the spread of the virus to healthy trees.
- Plum dwarf virus cannot be treated in apricot trees.
- There is no known cure for plum dwarf virus in apricot trees.
- Once apricot trees are infected with plum dwarf virus, they will remain infected for their lifespan.
- Prevention is the best method to avoid plum dwarf virus in apricot trees.
- Practices such as using virus-free planting material and controlling aphids can help reduce the risk of plum dwarf virus in apricot trees.
Are there any resistant apricot varieties to plum dwarf virus?
While there are no completely resistant apricot varieties to plum dwarf virus, some varieties may exhibit tolerance or reduced symptoms when infected. It is advisable to choose varieties that are known to have some level of resistance or tolerance to the virus.

| Goldrich | Resistant | University of California, Davis |
| Goldstrike | Resistant | University of California, Davis |
| Patterson | Susceptible | University of California, Davis |
How can you control aphids to prevent plum dwarf virus in apricots?
To control aphids and prevent the spread of plum dwarf virus in apricots, several measures can be taken. These include regularly inspecting the trees for aphid infestations, using insecticidal soaps or oils to kill aphids, promoting natural predators like ladybugs, and practicing good garden hygiene by removing and destroying infected plant material.
To prevent plum dwarf virus in apricots, control aphids by using insecticidal soaps, neem oil, or introducing beneficial insects like ladybugs.
Can plum dwarf virus spread to other fruit trees?
Yes, plum dwarf virus can spread to other fruit trees through aphid transmission. While it primarily affects plum and apricot trees, it can also infect other stone fruit trees such as peaches, nectarines, and cherries. Proper monitoring and control measures should be implemented to prevent the spread of the virus to other trees.
Plum dwarf virus is specific to plum trees and does not spread to other fruit trees.
Are there any preventive measures to protect apricot trees from plum dwarf virus?
Preventing plum dwarf virus in apricot trees involves several measures. These include using disease-free planting material, selecting resistant or tolerant varieties, practicing good garden hygiene, controlling aphid populations through regular monitoring and appropriate insecticides, and removing and destroying infected trees or plant material.
Plant resistant apricot tree varieties
Planting apricot tree varieties that are resistant to plum dwarf virus is one of the preventive measures. These resistant varieties have been bred to have natural resistance to the virus, reducing the risk of infection. Some examples of resistant apricot tree varieties include ‘Harcot’, ‘Goldrich’, and ‘Tilton’.
Practice good sanitation
Practicing good sanitation in and around the apricot trees can help prevent the spread of plum dwarf virus. This includes removing and destroying any infected plant material, such as leaves or prunings. Additionally, regularly cleaning and disinfecting tools used for pruning or other tree maintenance can also help prevent the virus from spreading.
Control aphid populations
Aphids are known vectors of plum dwarf virus, meaning they can transmit the virus from infected trees to healthy ones. Controlling aphid populations can help reduce the risk of virus transmission. This can be done through various methods such as using insecticidal soaps or oils, introducing natural predators of aphids, or practicing companion planting with plants that repel aphids.
