Peach pocket disease is a common problem affecting plum trees. This article provides a concise overview of this disease, its symptoms, and effective management strategies. Discover how to identify and prevent peach pocket disease in plums to ensure the health and productivity of your orchard.
Peach pocket disease in plums is a common problem that affects plum trees, causing significant damage to their fruits. This fungal infection, caused by the pathogen Taphrina communis, results in the formation of small, deformed pockets on the surface of plums. These pockets are characterized by their peach-like appearance and can render the fruits unmarketable. Plum growers must be vigilant in identifying and managing this disease to prevent its spread and minimize crop losses. Early symptoms include yellowish-green spots on young fruit, which eventually develop into the distinctive pockets. To control peach pocket disease, it is crucial to implement preventive measures such as pruning infected branches, applying appropriate fungicides, and maintaining proper tree hygiene. Regular monitoring and early intervention are essential for effectively managing this destructive disease and ensuring healthy plum harvests.

What is Peach Pocket Disease in Plums?
Peach Pocket Disease is a fungal disease that affects plum trees. It is caused by the fungus Taphrina deformans and primarily affects the fruit, causing them to become deformed and pocket-like. The disease can also affect the leaves and shoots of the tree.
| Definition | Symptoms | Prevention and Treatment |
| Peach Pocket Disease is a fungal infection that affects plum trees. | Leaves develop small, round, red or purple spots. Fruits become deformed, swollen, and discolored. | Prune affected branches, promote good air circulation, and apply fungicides. Plant disease-resistant plum tree varieties. |
| The fungus Taphrina deformans causes Peach Pocket Disease. | Infected leaves may drop prematurely. Fruits may crack, ooze sap, and rot. | Remove and destroy infected plant debris. Avoid overhead irrigation. Improve tree health through proper watering and fertilization. |
| Peach Pocket Disease can weaken plum trees and reduce fruit yield. | Young shoots may be stunted. Fruits may have a rough texture and an unpleasant taste. | Monitor your plum trees regularly for signs of infection. Follow proper sanitation practices. Consult with a local horticulturist for specific recommendations. |
How does Peach Pocket Disease spread?
Peach Pocket Disease spreads through spores produced by the fungus. These spores are released from infected fruit or plant parts and can be carried by wind or rain to nearby trees. The disease is more likely to spread in warm and humid conditions, which are favorable for fungal growth.
- Peach Pocket Disease can spread through infected peach trees.
- The disease can be transmitted through grafting infected plant material onto healthy trees.
- Insects, such as aphids, can also spread Peach Pocket Disease from infected trees to healthy ones.
What are the symptoms of Peach Pocket Disease in Plums?
The symptoms of Peach Pocket Disease in plums include small, round pockets or depressions on the fruit surface. These pockets may be green, red, or purple in color and can cause the fruit to become misshapen. Infected leaves may also show discoloration, curling, or distortion.
- Stunted growth
- Yellowing and curling of leaves
- Wilting of branches
- Small and distorted fruits
- Cracked bark
How can Peach Pocket Disease be controlled?
To control Peach Pocket Disease, it is important to practice good orchard sanitation. This includes removing and destroying infected fruit and plant debris. Fungicide sprays can also be applied during the dormant season to protect against infection. Proper pruning and thinning of trees can help improve air circulation and reduce humidity, which can inhibit fungal growth.
| Pruning and Sanitation | Chemical Control | Resistant Varieties |
| Regularly pruning infected branches can help control the spread of the disease. | Applying fungicides at recommended intervals can help prevent and control Peach Pocket Disease. | Planting and cultivating resistant varieties can minimize the risk of Peach Pocket Disease. |
| Removing and destroying infected plant debris can reduce the disease’s presence in the orchard. | Consulting with agricultural experts to determine the appropriate fungicides and application methods is crucial. | Choosing varieties that are known to have resistance to Peach Pocket Disease is an effective control measure. |
| Properly disposing of pruned branches and fallen leaves can prevent disease recurrence. | Follow the instructions on the fungicide label for optimal control and safety. | Resistant varieties can limit the severity and impact of Peach Pocket Disease. |
Are there any resistant plum varieties to Peach Pocket Disease?
While no plum varieties are completely resistant to Peach Pocket Disease, some varieties may exhibit better tolerance than others. It is recommended to choose disease-resistant varieties when planting plum trees. Consult with local nurseries or agricultural extension services for recommendations on suitable varieties for your area.
There are some plum varieties that are resistant to Peach Pocket Disease.
Can Peach Pocket Disease spread to other fruit trees?
Peach Pocket Disease is primarily a disease of plums, but it can also affect other stone fruit trees such as peaches and nectarines. The fungus Taphrina deformans can infect a range of host plants within the Prunus genus. Proper sanitation and preventive measures should be taken to minimize the spread of the disease to other fruit trees.

How can I prevent Peach Pocket Disease in my plum trees?
To prevent Peach Pocket Disease in plum trees, it is important to follow good cultural practices. This includes planting disease-resistant varieties, providing adequate sunlight and air circulation, practicing proper pruning and thinning, and removing and destroying infected plant material. Regular inspection of the trees for any signs of disease can help in early detection and management.
1. Maintain proper tree health:
Regularly inspect your plum trees for any signs of stress or disease. Ensure they receive adequate sunlight, water, and nutrients. Prune them annually to improve air circulation and remove any dead or diseased branches. Healthy trees are less susceptible to Peach Pocket Disease.
2. Practice good sanitation:
Remove and destroy any fallen leaves, fruit, or prunings from the ground. These can harbor the fungal spores that cause Peach Pocket Disease. Also, avoid planting plum trees near other stone fruit trees or wild Prunus species, as they can serve as potential sources of infection.
3. Apply preventive fungicides:
Before the flowering stage, apply fungicides labeled for Peach Pocket Disease control. Follow the instructions provided by the manufacturer regarding dosage and timing. Applying these fungicides can help protect your plum trees from the fungal infection.
