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 two isolates of TYLCV that are most commonly found in affected countries are tomato yellow leaf curl Sardinia virus (TYLCSV) and tomato yellow leaf curl virus-Israel (TYLCV-Isr). The first detection of TYLCV was confirmed through blot hybridization, PCR, and genome sequencing in the Dominican Republic in 1994.
The humidity may be used as a surrogate for leaf wetness, as it is an essential component of an environment and has data that can be easily measured. This pathogen is an especially prominent foliar disease of tomato in Florida, which provides the optimal high humidity environment for the disease growth and development.
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
Darkening lesions on tomato leaves Advanced necrosis on tomato leaf. Stemphylium solani is of greatest concern in tomatoes, potatoes, peppers, garlic, onions, and cotton, though a wide range of over 20 species have proven susceptible. In tomatoes and potatoes, the resulting disease is known as grey leaf spot. In alliums it is known as leaf ...
Begomovirus is a genus of viruses, in the family Geminiviridae. [1] They are plant viruses that as a group have a very wide host range, infecting dicotyledonous plants. . Worldwide they are responsible for a considerable amount of economic damage to many important crops such as tomatoes, beans, squash, cassava and c

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]
