White Mold of Pepper

Capsicum annuum L.

A fungal disease of pepper caused by the pathogen Sclerotinia sclerotiorum, manifesting as tissue softening, the formation of white mycelial growth, and black sclerotia, leading to rapid wilting of the plant.

In the reference 4 varieties crop Bell pepper, where this is mentioned in the description.

The causative agent of the disease is the fungus Sclerotinia sclerotiorum, which infects the roots, basal part of the stem, leaves, flowers, and fruits of the crop. The primary signs of infection are the appearance of water-soaked, slimy spots, after which the affected areas become covered with dense white web-like or cottony mycelial growth.

A characteristic diagnostic feature is the formation of black sclerotia inside or on the surface of stems and fruits. As the disease develops, tissues become slimy and soft, gum may form inside the stems, and the stems themselves often crack, which causes rapid wilting and death of the entire plant.

On fruits, symptoms of white mold are most often recorded during storage or in the presence of mechanical damage, such as cracks. Currently, no specific data on pathogen races associated with Capsicum annuum, as well as reliable sources of genetic resistance in the gene pool of this crop, have been identified.
