First report of tomato leaf curl New Delhi virus in China
Tomato leaf curl New Delhi virus (Begomovirus, ToLCNDV – EPPO A2 List) is reported for the first time in China. In August 2021, virus-like symptoms were observed on tomato (Solanum lycopersicum) plants grown in a greenhouse (approximately 0.5 ha) in Zhejiang province. Laboratory analysis (PCR tests, sequencing) confirmed the presence of ToLCNDV in a symptomatic sample. Further PCR tests also confirmed the presence of ToLCNDV in 8 tomato plants showing upward leaf curling and leaf distortion. Considering the widespread occurrence of the virus vector, Bemisia tabaci, in China, it is noted that ToLCNDV may represent a potential threat to tomato cultivation in China.
The situation of tomato leaf curl New Delhi virus in China can be described as follows: Present, not widely distributed.
