What is Tree Rust?
Tree rust is a fungal infection that attacks trees, with a particular focus on their leaves. There are thousands of different species of rust fungi, each of which is suited to a different type of plant.
All of these fungi have certain symptoms in common, namely:
- Early Discoloration- Rust begins by leaving small discolored spots on the undersides of your plant leaves. These spots may appear white at first, but will gradually become darker, transitioning to shades of yellow, orange, red, and brown.
- Budding Bumps- As the fungus spreads and darkens, it tends to protrude out from the leaves it attacks. You will start to notice small, discolored bumps.
- Leaf Deformation- If you leave rust to fester for long enough, it will start to impact the health of the leaves. Leaves will wither, darken, and fall off, making it harder for the plant to obtain energy from the sun.
Tree rust is similar to lawn rust in its appearance and effect, but each is caused by a different species. Because the fungi that cause rust are specifically suited for each type of plant, you do not usually have to worry about disease spreading from one type of plant to another. But it can spread between plants of the same type, making it important for you to eliminate the fungus and address the conditions that caused it to spread as quickly as possible.
How Safari Tree Treats Tree Rust
When you report rust, Safari Tree will immediately inspect your trees to determine the specific type of rust disease that you are dealing with. We then set to work removing every leaf that has been infected, disposing of these leaves in a way that will not expose other trees. By removing affected leaves, we limit the potential for rust fungi to spread onto other parts of your trees or other trees of the same species, containing the scope of the threat.
Once all affected leaves have been removed, we will treat your plant with a fungicide. This will kill any remaining bits of rust fungi that we are unable to identify or remove, as well as spores that have not yet taken root. Our team will provide multiple treatments depending on the extent of the threat; we are also happy to inspect your trees after the initial treatment and treat them again if we find more disease.
Besides after-the-fact treatments, Safari Tree provides preventative plant care. Through our Tree Health Care Program, we apply preventative fungicides while making sure your plants have the nutrients they need to shake off any disease. This decreases the risk that rust or some other fungal disease will affect your foliage in the first place, keeping trees healthy for the long haul.
