Grey mould or gray mold (Botrytis cinerea) is a fungal pathogen of plants with a wide variety of hosts. B. cinerea is also a cause of damping off in seedlings.
Identifying Features[]
Grey mould usually starts on a damaged area of stem. Other parts of the plant may then be infected - diseased flower stalks cause fruit drop.
Treatment[]
Cut out diseased areas and remove all rotting parts.
Prevention[]
Reduce humidity by adequate ventilation and avoid overcrowding. Remove decaying leaves and fruit. No systemic sprays are available.
