Fusarium wilt is a disease that restricts carnation (Dianthus caryophyllus L.) yield worldwide. Efficacies in reducing the Fusarium wilt of carnation (FWC), of various types of organic amendments (fresh or pelletized poultry manure, pelletized Brassica carinata and olive residue compost) combined with soil solarization, were compared in two biennial field trials conducted in a greenhouse with a history of carnation monoculture over 8 years. Soil treatments combining organic amendments and soil solarization significantly reduced disease incidence (86–99%) and increased the number of commercial carnation stems by 5–9 times compared to non-treated plots. Twenty-one Fusarium spp. isolates, with different colony morphologies were recovered from soil samples taken in the greenhouse, before the application of treatments in June 2013. Nineteen of them were morphological and molecularly characterized. Additionally, two pathogenicity tests with 17 isolates recovered from greenhouse soils and two isolates recovered from organic amendments were performed. Fusarium species associated with carnation cultivation were identified as Fusarium oxysporum (43%), Fusarium proliferatum (24%), and Fusarium solani (33%). The phylogenetic analysis of the translation elongation factor 1 alpha (EF-1α) region distinguished highly aggressive isolates of F. oxysporum f. sp. dianthi, from low aggressive isolates. The pathogenicity tests showed that FWC has a complex etiology, with several Fusarium spp. identified as causal agents. F. proliferatum and F. solani are associated with carnation wilt for the first time in Spain.
