The primary host for TYLCV is the tomato plant, and other plant hosts where TYLCV infection has been found include eggplants, potatoes, tobacco, beans, and peppers. [1] Due to the rapid spread of TYLCV in the last few decades, there is an increased focus in research trying to understand and control this damaging pathogen.
Pests, herbicides, or environmental factors can all cause tomato leaves to curl. Learning to recognize the cause is the first step toward solving this common problem.
Of these, the most severely affected include tomatoes, lettuce, pepper and peppermint as well as most all ornamentals. [6] Symptoms of infection include a downward curling of the leaves, leaf tip dieback, stunting, necrosis of growing leaf tips, sunken 'chicken pox-like' spots on leaves (often with a surrounding halo), stem death and yellowing.

Tomato leaf mold is a plant disease originated from the South and Central America. [1] In 1883, Cooke first discovered the tomato leaf mold in North Carolina. [2] This disease is not common on the fruit, but if the control is not run, the foliage can be greatly damaged and result in significant yield losses.
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. [2] Beet curly top virus causes curly top disease in beets and is carried by the beet leafhopper (Circulifer tenellus) [3] throughout arid and semi-arid locations. [4]

Celebrity tomatoes are resistant to Verticillium Wilt, a fungal disease which causes a yellow colour to plant leaves and eventually causes the leaves to wilt and die. [19] It is also resistant to Fusarium Wilt which is a fungus found in the soil that infects the roots of plants, stopping plant growth and causing leaf necrosis. [ 11 ]
The plant pathogen causes a yellow leaf disorder in solanaceous crops including tomatoes. [1] ToCV is transmissible by whiteflies, phloem-limited and causes symptoms of interveinal chlorosis followed by necrosis in the tomato plants leaves resulting in a reduced fruit yield. [1] ToCV has a wide range of hosts such as pepper and potato. [4]
