Additionally, the pathogenicity of selected Fusarium spp. isolates was determined. A. officinalis L. was cultivated for white spears. The research was conducted on the German dioecious cultivar ‘Eposs’. Samples of A. officinalis spears for tests were collected from two plantations. Six species of fungi of the Fusarium genus were identified in the asparagus spears: F. culmorum, F. equiseti, F. oxysporum, F. proliferatum, F. solani, and F. fujikuroi. Among the Fusarium species colonizing Asparagus officinalis the greatest threat is F. oxysporum. Always there are more isolates in the spears with the symptoms, in epidermis. The late harvest date favors the development of fusariosis. This means that the spears harvested at the latest date (late June) are the most heavily colonised by fungi. The isolates of fungi of the Fusarium genus collected from the spears exhibit pathogenicity against A. officinalis plants.</p> ER -
