Detection kits for CSVd Available in TaqMan format for analysis The Chrysanthemum Stunt Viroid (CSVd) is the causal agent of a disease known as chrysanthemum stunt. The viroid consists of small pieces of RNA (354 bp) that are known to be highly contagious. The main symptoms of CSVd infection are severe stunting of the plants such that they are half to two-thirds of the normal size, as well as smaller flowers and premature flowering. Symptoms of Chrysanthemum Stunt are difficult to detect in stock, however can be so severe at flowering that finished crops of flowers are unmarketable. There is no chemical that can control CSVd, therefore much effort has been made to generate chrysanthemum plants free from CSVd. Norgen’s Chrysanthemum Stunt Viroid Detection Kits are a rapid and sensitive CSVd detection tool which can be applicable for the early diagnosis of CSVd.
