How to Identify Signs and Symptoms of Dutch Elm Disease
Dutch Elm Disease is a devastating fungal disease that affects elm trees, causing wilt and eventual death. It is important to be able to identify the signs and symptoms of this disease in order to effectively diagnose and manage it. Here are step-by-step instructions on how to do so:
1. Look for wilted branches: One of the first signs of Dutch Elm Disease is wilting branches. Keep an eye out for branches that suddenly droop and turn yellow or brown, especially during the summer months.
2. Check for yellowing leaves: Infected trees will often exhibit yellowing leaves that may curl and become dry. This is a result of the disease blocking the tree’s water-conducting vessels.
3. Look for brown streaks in the wood: Peel back the bark of an infected branch and examine the wood. If you see brown streaks running through the wood, it is a strong indication of Dutch Elm Disease. The discoloration is caused by the fungus growing within the tree’s vascular system.
4. Observe beetle activity: Dutch Elm Disease is primarily spread by elm bark beetles. If you notice an increase in beetle activity around your elm trees, it is important to take immediate action to prevent the spread of the disease.
