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.
Tomato yellow leaf curl China virus (TYLCCNV) is a virus which contains 25 isolates. It infects plants as different as tobacco and tomato, as well as genetically modified plants. Petunias can be infected, but show no symptoms. The microbiology of the virus has been studied in the Chinese province of Yunnan.
Symptoms of tomato yellow leaf curl virus, including chlorotic margins and interveinal yellowing, were found in several tomato and tomatillo crops in Mexico and Guatemala in 2006. [31] After laboratory tests, the virus was confirmed. Symptomatic plants were associated with the presence of whiteflies, which were likely the cause of this outbreak ...
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]
Tomato leaf curl China virus is a virus that infects tomato plants in China and was first described in 2011. The virus infects tomatoes in the Chinese province of Guangxi, and it is transmitted by the whitefly. [1] The current EPPO name is TOLCCV, but its original name in the literature was ToLCCNV. [2]
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.

Prevalent in tomatoes but also found in peppers, squash, cucumber, eggplant and watermelon, this physiological disorder is purely the result of a calcium deficiency within the plant itself ...
