Different Types of Tree Diseases

Cypress is one of the most common and destructive types of tree diseases in the world. Cypress trees are most commonly planted in moist tropical environments such as in Florida and Mexico, however they are also found in other tropical regions of the world such as Central America. The diseases that can affect Cypress trees include the insect heart leaf disease (DE), the black leaflet fungal infection (B FL), and the cypress leaflet fungal infection (C FL). Each of these tree diseases have different names meaning different things in different areas of the world.

The most common of these infections is the Dollar Spot Virus or DFSV. This virus damages the leaflet tissue causing the leaves to yellow quickly and becoming droopy and curled. The infected leaves may curl into the shape of a Dollar sign and eventually drop off. Other times the infected leaves may die from the infection.


Another of the tree diseases affecting cypress trees is the Black Leaflet (B FL) which is also called the “dwarf leaflet.” These viruses attack cypress leaves by causing them to wither, die, and wither away. The affected leaves may die from the infection and produce black dots on the infected leaves. This disease is usually found in humid climates.


The last of the tree diseases affecting cypress is the cypress mosaic virus. This is a waxy, sticky fungus that affects cypress leaves. As the parasite grows it eats through the sapwood and releases its feces on the infected leaves. As the fungus matures, it changes color and begins to form black, purple, white, and brown fibers. The final stages of this disease result in the death of the cypress leaf and the entire tree.


A third disease of the cypress is the Stomatitis Virus. This is also known as the Black spot ailment. This is an aseptic fungal disease. A ring of red sores forms around the infected area and the infected leaves turn black and fall. The diameter of the rings can range from one to two inches.


All three of these tree diseases are preventable if the owner of the tree takes the necessary precautions. The first step is to keep the tree well watered. Cypress requires an adequate amount of water to remain healthy and prevent drying out. It is also important to fertilize the tree every few months to help prevent leaf decay and to promote growth.


All of these tree diseases can be avoided by taking preventative measures to avoid exposure to the diseases. The owners of cypress trees should make sure that they do not allow branches of the tree to reach the ground or any area where it can get exposed to rain or other elements. It is also important to cut any dead, dying, or damaged leaves from the trees. Clean the leaves thoroughly with a leaf blower before using it again.


There are a number of different treatment options available for the prevention of each of these diseases. There are commercial products available for the treatment of fungal infections. There are natural remedies that can be used to prevent exposure to these infections. There are preventive steps that can be taken to avoid attack by these parasites. Prevention is key to preventing disease and killing off the diseases.


Leaf Spot on Cypress: This fungal disease attacks mainly conifers and young seedless cypress trees. It begins as small white spots on the leaves of the tree. As it grows, the spots will spread until there are plenty of white spots covering the entire leaves of the tree. The fungus is known to survive in humid conditions. The fungus thrives on damp leaves and will spread when a humidifier is used in the area where the infected tree is located.


Fungal Infection on the Tree Bark: It is also known as the “black plague.” It is a severe disease that attacks the bark of the tree. Millions of dollars are spent each year in the United States to eradicate the fungus from infected trees.


As you can see, there are many different types of tree diseases to worry about. Knowing the name of the tree disease is important because treatment can vary depending on what type of tree you have. Prevention is always better than cure, so you need to know what type of tree disease your particular tree has in order to prevent an outbreak from occurring.
