 Curly top virus, have a very wide host range within dicot plants, including over 300 species in 44 plant families (Strausbaugh et al., 2008).The most common infected hosts include sugar beets (for which the disease was first named), follow by tomatoes, peppers, beans, potatoes, spinach, cucurbits, cabbage, alfalfa, and many ornamentals.The virus seems to be restricted to trees with broad leaves, because no single-leafed plants were identified as the host of this virus.
