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 FeaturesEdit

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.

TreatmentEdit

Cut out diseased areas and remove all rotting parts.

PreventionEdit

Reduce humidity by adequate ventilation and avoid overcrowding. Remove decaying leaves and fruit. No systemic sprays are available.
