Tomato yellow leaf curl virus occurs in Zhejiang province, China
In China, the presence of Tomato yellow leaf curl virus (Begomovirus – EPPO A2 List) was first reported in Shanghai in 2006 (EPPO RS 2007/187). In the autumn-winter cropping season of 2006, a severe outbreak of tomato yellow leaf curl disease was reported in field grown tomatoes in several areas (Jiaxing, Haining, Ningbo and Wenzhou) of the Zhejiang province. The infested sites were located along the coast to the south-west of Shanghai. Molecular studies confirmed the presence of 2 begomoviruses: Tomato yellow leaf curl virus (TYLCV) and Tomato leaf curl Taiwan virus (ToLCTWV). TYLCV was detected in Jiaxing, Haining and Ningbo, and ToLCTWV was detected in Wenzhou. As high populations of Bemisia tabaci biotype B are present in this region, it is considered that both viruses present a serious threat to tomato crops.
The situation of Tomato yellow leaf curl virus in China can be described as follows: Present first found in 2006 in Shanghai and later in nearby coastal areas in Zhejiang province.
