Chrysanthemum stunt viroid (CSVd), a common pathogen of chrysanthemums, is spread by contact and by propagating infected plants. The viroid can cause severely stunted plants and unsalable flowers. If your supplier of chrysanthemum cuttings has an effective program of testing for CSVd, it is unlikely this pathogen will be present in your plants. We detect CSVd and Chrysanthemum chlorotic mottle viroid using a nucleic acid hybridization test, which requires several days to complete. Chrysanthemum chlorotic mottle viroid may or may not produce symptoms.
Other pathogens often detected in chrysanthemums are Chrysanthemum virus B and Cucumber mosaic virus, both transmitted by aphids, and Tomato spotted wilt and Impatiens necrotic spot viruses, both transmitted by thrips.
