First report of Chrysanthemum stem necrosis tospovirus in United Kingdom
In November 2002, diseased samples of chrysanthemum were sent for laboratory testing to CSL, United Kingdom. Samples showed distinct dark stem lesions and sometimes leaf necrosis. They had been collected from chrysanthemum plants (cv. Fiji and Calabria) grown under glasshouse in South West England. The crop originated from cuttings imported from Brazil. Considering these symptoms and the absence of fungal pathogens, samples were tested by ELISA for the presence of three tospoviruses: Chrysanthemum stem necrosis, Tomato spotted wilt and Impatiens necrotic spot. Only Chrysanthemum stem necrosis tospovirus (EPPO Alert List) was found in diseased samples. Its presence was confirmed by electron microscopy and mechanical inoculation to a range of indicator plants. This is the first report of Chrysanthemum stem necrosis tospovirus in United Kingdom. The infested crop has been removed and measures taken to eradicate the infection.
The situation of Chrysanthemum stem necrosis tospovirus in United Kingdom can be described as follows: Present, only in protected cultivation. Found in 2002 on chrysanthemum in South West England, under eradication.
