The disease is caused by the specialized pathogen Fusarium oxysporum Schl. f. sp. conglutinans, which consists of two physiological races. Race 1 is widespread in Europe, while race 2 is considered a more aggressive strain causing significant damage in a number of regions. The fungus infects the plant at any stage of vegetation, penetrating the vascular system and causing loss of turgor, unilateral yellowing, and leaf deformation.
A diagnostic sign of the infection is the presence of a brown or light-brown ring in the tissues of the petioles and stem, formed by the pathogen's mycelium. In cabbage breeding for resistance to the disease, the Foc1 gene plays a key role, controlled using molecular markers such as FocBNUf/r and the SSR marker Ol10-D01. To evaluate the reaction of breeding material to the pathogen, resistance (HR) and susceptibility (S) standards are used.
