Grey mould (botyris)


Plants show leaf spotting and grey, fluffy mould on stems, leaves, flowers or fruit. Especially bad on plants in cold, damp conditions.

Cultural measures: Avoid over-watering and ensure good drainage. Avoid misting plants. Improve ventilation and increase plant spacing. Remove affected plant parts and any fallen plant debris.

There is no chemical registered for the control of this problem.
