Diseases
Chrysanthemum L.
A viral disease of chrysanthemum caused by Chrysanthemum stem necrosis virus (CSNV) of the genus Orthotospovirus. It is characterized by the appearance of necrotic lesions on stems, leaves, and reproductive organs, leading to plant death.
In the reference 4 varieties crop Chrysanthemum, where this is mentioned in the description.
The causative agent of the disease is Chrysanthemum stem necrosis virus, which belongs to the genus Orthotospovirus. The pathogen has a wide host range and is capable of adapting to various plant species; however, specific information regarding the existence of intraspecific races or pathotypes of CSNV in relation to chrysanthemum is currently unavailable.
Symptoms of the infection in large-flowered chrysanthemum manifest as streaks, stripes, or necrotic spots on the shoots, which, as the infection progresses, lead to stem dieback and plant death. Chlorotic or necrotic spots and ring patterns develop on the leaves, while necroses occur on the peduncles and receptacles, causing deformation and discoloration of the flowers.
Necrotic lesions on chrysanthemum tissues can also be caused by other agents, such as the fungus Botrytis cinerea or the Chrysanthemum stunt viroid (CSVd), which have a different etiology. Scientific data on specific resistance genes of chrysanthemum to CSNV are not currently presented in breeding literature.
