Tomato Spotted Wilt Virus
What are the prospects for Tomato Spotted Wilt Virus on floral crops in 1989? It appears things may get worse before they get better and tomato spotted wilt virus will continue to be a problem for greenhouse flower growers. At the Sixth Ornamentals Workshop on Diseases and Insects in Crossnore, NC, October, 1988, tomato spotted wilt virus was reported to have been diagnosed in one or more floral crops from most states in the U.S. and several areas in Canada. In North Carolina we have seen the disease in calceolaria, cyclamen and cineraria during the winter months. We have also seen the disease on New Guinea impatiens stock plants, rooted cuttings and hanging baskets, which is a potential threat to most of the bedding plants which are just being seeded at the time this is being written.
