Tomato yellow leaf curl virus TYLCV causes the most destructive disease of tomato, and it can be found in tropical and subtropical regions causing severe economic losses. This virus is transmitted by an insect vector from the family Aleyrodidae and order Hemiptera , the whitefly Bemisia tabaci , commonly known as the silverleaf whitefly or the ...
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.

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] The term curly top virus often refers to this specific virus. [2]

Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
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]
