- Curly top is a viral disease that affects many crops. This disease causes plants to become smaller in size, have shriveled petals and leaves, and are twisted and pulled out of shape. They are often caused by curtoviruses (genus Curtovirus), members of the virus family Geminiviridae. This disease is important in western United States, such as California, Utah, Washington, and Idaho. Curly top is characterized by stunting of the plant and deformation of leaves and fruit. The petioles and blades of the leaves curl, twist, and become discolored.
* Beet curly top virus causes curly top disease in beets and is carried by the beet leafhopper (Circulifer tenellus) throughout arid and semi-arid locations. The term curly top virus often refers to this specific virus. It can also cause curly top in tomatoes, beans, cucurbits, and other crops. This disease can be reduced if plants are planted in the shade because the beet leafhoppers and other insects like to feed on these plants in the sun.
* Curly top disease in spinach can be caused by Beet curly top virus, , or .
* Other curly top curtoviruses include , , and . Turnip curly top virus may also be a species of Curtovirus. (en)
