Which symptoms are associated with Gray mold?

The symptoms associated with Gray mold, caused by the fungus Botrytis cinerea, prominently include lesions on fruit and a characteristic coat of mycelium. This fungus typically affects a wide range of plants and can infect various plant parts, especially during damp, humid conditions.

Lesions on fruit manifest as sunken, water-soaked spots that can eventually turn brown and soft, indicating the decay process initiated by the pathogen. The coat of mycelium appears as a fuzzy, greyish layer on the affected tissues, which is a hallmark of advanced infection. This visual identification is critical for recognizing Gray mold and effectively managing its impact on crops. Such knowledge is essential for implementing appropriate control measures, including proper cultural practices and fungicide applications, to mitigate losses due to this destructive pathogen.
