Plant disease has a number of negative effects, both aesthetic and structural. In extreme cases, plant disease can weaken a tree, making it more likely to fall and cause property damage or personal injury. To avoid these hazards and the need for emergency tree removal, it is important to be familiar with the signs of common tree diseases in Florida. Gainesville arborists with SkyFrog Tree Service warn homeowners of the more common tree diseases found in the area.
Apple scab is a fungal disease that affects crabapples. Yellow or green scab-like lesions form on the leaves of the tree, eventually causing the leaves to drop. Apple scab is not directly harmful or fatal to trees, but it is aesthetically unappealing. Arborists in Gainesville can treat the issue with fungicidal agents.
Dothistroma needle blight, also known as brown spot needle blight, is the most serious tree disease affecting the longleaf pine. The disease stunts the growth of saplings and causes premature defoliation in mature trees. Symptoms include small dots on the needles varying from yellow to light brown, eventually leading to the death of the needles. Homeowners who suspect needle blight should contact a tree care service in Gainesville that can treat the disease with a fungicide containing copper hydroxide and mancozeb.
Lethal yellowing affects palm trees in Florida and is caused by a bacteria-like organism called phytoplasma, which is carried by a planthopper insect. Symptoms of lethal yellow include flower death, premature fruit dropping, and yellow foliage. An arborist service in Gainesville can treat this condition by injecting an antibiotic into the tree trunk.
Oak wilt is a systemic fungal disease that can lead to the death of the tree. Symptoms of this disease include wilted leaves, rapid discoloration, and premature defoliation. Arborists can treat trees in the white oak family for oak wilt, but infected red oaks will necessitate a tree removal service. Homeowners and arborists can prevent oak wilt by injecting trees with systemic fungicide during the growing season.
This is a condition caused by fungal pathogens that grow on the surface of the plant, producing white fungal threads and spores. The fungus attacks young tissue, resulting in leaf, flower, and shoot distortion, which becomes dry and brown. Fungicides can be used to treat the condition, and arborists in Gainesville can assist homeowners in selecting tree varieties that are resistant to the pathogens.
