Mould

One of the most common moulds found on blueberries is Botrytis or grey mould. The mycelium is grey and fluffy. Actions during growth in the field can reduce its presence. Botrytis may also remain latent until the fruit softens or by entering the fruit through damages such as bruises. Although, cooler temperature will not stop the growth of Botrytis, it will significantly slow it down and extend the shelf-life of the blueberry.
