tomato leaf curl virus
Tomato yellow leaf curl virus (TYLCV) is a plant pathogenic virus of the family Geminiviridae. It is transmitted by the silverleaf whitefly.In March 2006, tomato leaf curl disease was found in cherry tomato crops in the south and west periphery of Brisbane. The disease has been found in many crops, with infection levels ranging from 5 to 100 per cent of plants.
Losses in severely affected crops have been very high and the disease is a major threat to tomato production. In April 2006, infected plants were also found around Bundaberg. By June 2007, the virus was present in the Lockyer Valley, Fassifern Valley, Esk, Caboolture and Redlands areas. Since 2009 it has become a serious production constraint around Bundaberg. In February 2011, it was found in backyard tomato plants in Mareeba on the Atherton Tablelands.
Tomato leaf curl disease is caused by viruses in the Geminivirus family of plant viruses, and is spread by whiteflies.
The virus causing this disease is tomato yellow leaf curl virus (TYLCV). This virus is distinct from tomato leaf curl Australia virus (TLCV), which occurs in the Northern Territory and at several locations on Cape York Peninsula.
