Bacterial disease induced by Erwinia chrysanthemi pv dianthicola is a limiting factor for Dahlia production. There are also diseases caused by four important viruses: Dahlia mosaic virus (DaMV), Tobacco Streak Virus (TSV) Tomato Spotted Wilt Virus (TSWV) and Cucumber Mosaic Virus (CMV). These pathogens are transmitted essentially through vegetative propagation (cutting, bulb).

In order to improve phytosanitary status of Dahlia, more precise diagnosis with immunoenzymatic methods, carried out for the detection of Erwinia chrysanthemi and viruses, and in vitro multiplication conditions allowing rapid increase of tested plantlets and obtainment of commercial tubers in the year, were defined and ameliorated.
