Dutch Elm Disease (DED) is a fungal infection that affects all species of elm trees native to Minnesota. It is caused by the invasive pathogen Ophiostoma novo-ulmi and is spread by elm bark beetles and through root grafts. Symptoms of DED include yellowing and wilting of leaves, brown streaking along the sapwood, and the eventual death of the tree. Fungicide injections, pruning infected branches, and using DED-resistant varieties are some of the treatment options available for managing and controlling DED.
Key Takeaways:
- Dutch Elm Disease (DED) is a fungal infection that affects elm trees in Minnesota.

- Symptoms of DED include yellowing and wilting of leaves, brown streaking along the sapwood, and tree death.
- Treatment options for DED include fungicide injections, pruning infected branches, and using resistant varieties.
- Effective DED treatment can help manage and control the disease, protecting the health of elm trees.
How to Identify Dutch Elm Disease
Dutch Elm Disease (DED) is a serious fungal infection that affects elm trees, and early identification is crucial for effective treatment. By knowing how to identify the signs of DED, you can take the necessary steps to protect your trees and prevent the spread of the disease.
One of the first signs of Dutch Elm Disease is the yellowing, wilting, and browning of leaves on infected branches. These leaves may also fall and accumulate on the ground, creating a noticeable presence in your yard.
When inspecting the branches, removing the bark will reveal brown streaking along the sapwood. This discoloration is a clear indicator of DED and helps distinguish infected branches from healthy ones.
To confirm the presence of Dutch Elm Disease, it is recommended to send a sample of live branches displaying wilting symptoms to a plant disease diagnostic clinic. Their experts can analyze the sample and provide a definitive diagnosis.
It’s important to note that all native species of elm, including American elm, red or slippery elm, rock elm, Chinese elm, Japanese elm, and Siberian elm, are susceptible to DED. Therefore, if you observe these symptoms on any of these elm tree varieties, it is crucial to take immediate action.

How Dutch Elm Disease Spreads
When it comes to Dutch Elm Disease (DED), understanding how it spreads is crucial for effective management. DED spreads through two main methods: bark beetles and root grafts.
Elm bark beetles play a significant role in the spread of DED. These beetles, including the smaller European elm bark beetle, the banded elm bark beetle, and the native elm bark beetle, carry spores of the DED fungus from infected trees to healthy ones when they feed. As they move from tree to tree, they unknowingly transport the pathogen, increasing the risk of infection.
Root grafts also play a significant role in DED spread. When the roots of neighboring elm trees come into contact, they can graft together, creating a connection for the disease to move from one tree to another. The DED fungus produces a thread-like growth known as mycelium, which extends downward towards the root system. This mycelium can infect nearby trees through these root grafts, causing the disease to spread within a grove or stand of elms.
Understanding these modes of spread is essential for implementing effective control measures to prevent the further spread of DED. By targeting and managing the beetles and severing root grafts, we can help protect the health and longevity of our beloved elm trees.
Managing Dutch Elm Disease
Dutch Elm Disease (DED) requires proactive management to protect and preserve the health of affected trees. One essential aspect of managing DED is reducing the breeding sites for elm bark beetles. To achieve this, it is crucial to promptly remove dead or dying elm wood with intact bark to eliminate potential habitats for these pests.
Infected branches should be pruned out in the same year the infection starts, as this helps prevent further spread within the tree. For trees with multiple infected branches, it may be necessary to consider taking them down to prevent the disease from spreading to neighboring healthy trees.
Proper disposal of wood from infected elm trees is also vital in managing DED. Options such as burying, debarking, burning, or chipping help eliminate the disease-causing fungus and minimize the risk of contamination.
Severing root grafts between infected and healthy trees is another critical step in disease management. By severing these connections, the spread of the disease through the root system can be stopped, protecting healthy trees from infection.
Choosing Dutch Elm Disease-resistant cultivars for new plantings is a proactive approach to prevent and manage the disease. These resistant varieties exhibit greater tolerance to DED and have a higher chance of survival if exposed to the pathogen.
Additionally, utilizing preventative fungicide injections can offer further protection to vulnerable trees. These injections deliver targeted treatment directly into the root system, helping eliminate the DED fungus and reducing the risk of infection.
Effective management strategies, including prompt removal of breeding sites, pruning infected branches, proper disposal of infected wood, severing root grafts, and proactive selection of resistant cultivars and fungicide treatments, are key to effectively managing Dutch Elm Disease and preserving the health of elm trees.
Dutch Elm Disease Treatment Options
When it comes to treating Dutch Elm Disease, there are several effective options available. These treatment methods aim to control the spread of the disease, eliminate the DED fungus, and protect the health of elm trees. Let’s explore some of the most common Dutch Elm Disease treatment options:
Removal of Dead and Dying Branches
One of the first steps in Dutch Elm Disease treatment is the removal of dead and dying branches. This helps eliminate breeding sites for Elm Bark beetles, which are responsible for spreading the disease. By promptly pruning and disposing of infected branches, you can disrupt the life cycle of these beetles and reduce their numbers.
Severing of Root Grafts
Another effective method to prevent the spread of Dutch Elm Disease is severing root grafts between infected and healthy trees. Root grafts can transfer the DED fungus from one tree to another, leading to the rapid spread of the disease. By cutting the root connections between infected and healthy trees, you can contain the infection and protect unaffected elms.
Fungicide Injections
Fungicide injections directly into the tree’s root system are another treatment option for Dutch Elm Disease. These injections deliver antifungal agents that target and eliminate the DED fungus, preventing further infection and helping the tree recover. Fungicide injections are most effective when administered by certified arborists or tree care professionals.
Pruning and Trimming Infected Branches
Pruning and trimming infected branches can also be an effective measure in controlling Dutch Elm Disease. By removing and properly disposing of the infected branches, you limit the risk of further fungal spread and protect the overall health of the tree. It’s important to ensure that pruning is done correctly and at the right time to maximize its effectiveness.
Planting DED-Resistant Tree Varieties
One of the most long-term and proactive approaches to managing and preventing Dutch Elm Disease is to plant DED-resistant tree varieties. Selecting and planting elm tree cultivars that have natural resistance to the disease can significantly reduce the risk of infection and minimize the need for extensive treatment.
To effectively treat Dutch Elm Disease, it is recommended to consult with certified arborists or tree care professionals who have experience in managing this disease. They can assess the condition of the trees, provide tailored treatment plans, and ensure the best possible outcomes.
