Diseases
Brassica oleracea L. (White Cabbage Group)
A fungal disease caused by the pathogen Sclerotinia sclerotiorum, manifesting as white mycelium, leaf decay, and the formation of sclerotia on heads.
In the reference 4 varieties crop White cabbage, where this is mentioned in the description.
The causative agent of the disease is the fungus Sclerotinia sclerotiorum, which infects plant tissues at the end of the growing season and develops actively during storage. Symptoms include the appearance of dense, white, cottony mold on the outer leaves and between them, within which black fungal sclerotia ranging from 1 mm to 3 cm in size are formed. The infection can spread to the stem, causing it to rot and leading to the wilting of the entire plant.
Overripe, frost-damaged, or mechanically injured heads are most susceptible to infection, while favorable conditions for the pathogen include high soil and air humidity at a temperature range of 10–25 °C. Highly effective natural sources of resistance to this disease are virtually absent in white cabbage; therefore, no specific resistance genes have been identified in breeding, and plant protection is based on the selection of cultivars with high storage longevity and head density.
