These are some of the most common tree diseases in Florida:



  1. Fusiform Rust – This is a very damaging disease that affects pine trees in Florida. It is caused by a fungus called Cronartium quercuum. The fungus spreads through the tree causing galls and cankers. If a tree is infected before the age of five, it can likely kill the tree. Fortunately, seedlings have been developed that have resistance to this disease.


  2. Oak Wilt – As the name suggests, Oak Wilt affects oak trees in Florida causing them to wilt and even die. The fungus Ceratocystis fagacearum is the cause of the disease. The spores that form give off an odor that attracts Nitidulid Beetles which tunnel through the tree and cause even more damage. If the infection grows, the tree may have to be removed by an expert to prevent the spread of the infection to nearby trees.


  3. Annosus Root Disease – This disease also affects pine trees. Heterobasidion annosum is the fungus responsible for this tree disease. It will typically enter through a wound on the tree and spreads which can slow the growth of the tree or even kill it. This can be especially dangerous because it causes the tree to lose its strength making it prone to breaking or falling due to high wind.


  4. Brown Spot Needle Blight – This disease affects the longleaf pine and results in brown spots on the needles of the pine tree. The fungus that causes this disease is known as Mycosphaerella dearnessii. It spreads fastest during warm, wet weather as the needles need to be wet in order to be infected. This disease slows tree growth and can even kill young trees.
