Eremascaceae fungi

The family Eremascaceae comprises a group of ascomycetous fungi that hold significant relevance in agricultural phytopathology, particularly concerning post-harvest storage. While many species within this taxon act as saprotrophs, they can manifest as opportunistic pathogens, leading to the spoilage of sensitive plant products and fruits.

The causative agents are characterized by their unique reproductive cycles and ability to thrive in specialized substrates. They typically function as secondary invaders, colonizing plant tissues that have already been weakened by environmental stress or physical damage. Their biology is closely linked to fermentation processes, which is why they are often studied in relation to food security.

Crops most frequently affected by these fungi include grapes, various berries, pome fruits, and stored grain products. The pathogen attacks the tissues where the protective barrier (epidermis or cuticle) is breached, allowing for rapid colonization and the subsequent breakdown of organic matter through fungal metabolic activity.

Symptomatology involves the appearance of visible fungal mats, tissue softening, discoloration, and distinctive odors associated with fermentation. If left unchecked, these fungi can lead to significant quantitative and qualitative losses, reducing the marketability of the harvest and potentially introducing mycotoxins into the product chain.

Protective measures are primarily focused on maintaining optimal storage conditions, including strict control of relative humidity and ventilation. Preventing mechanical injury during harvesting and ensuring thorough disinfection of agricultural facilities are vital prophylactic steps. In specific scenarios, pre-harvest application of appropriate fungicides may be necessary to suppress the development of Eremascaceae populations.
