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.
Oranges, lemons, lime, kumquats and grapefruit are only a few trees in the citrus family. Depending on the species, citrus trees grow in U.S. Department of Agriculture plant hardiness zones 9 through 12. When the leaves of the citrus tree begin to curl, you know something is wrong with the tree.phids, spider mites, citrus leaf miners, scale insects and mealybugs are a few of these sap-sucking pests that will cause the leaves to curl, wilt and die. Introducing predatory insects that feed on the sap-sucking pests will help keep their numbers in check.
