Two species of fire ants are found in Florida. Most notorious is Solenopsis invicta Buren, the red imported fire ant (RIFA), followed by the much less common Solenopsis geminata (Fabricius), the tropical or native fire ant.
Leaf curl is a plant disease characterized by curling of leaves, and caused by a fungus, genus Taphrina, or virus, especially genus Begomovirus of the family Geminiviridae.
Brown, curling leaves can be a symptom of a soilborne disease known as cucumber mosaic virus. Your best course of action is to treat the plant with a commercial fungicide. If that fails to remedy the situation, remove the infected plant and donât replant in the same area.
