Name: Grey mould (Botrytis)
Blights, spots, blotches, wilts, cankers, rots, damping off and storage diseases. Usually the softer tissues such as petals are blighted, though leaf spotting, stem blights and rotting of cuttings and seed occur, especially in crowded situations. Early symptoms are small spots, which can extend into large areas of blight and later the characteristic grey mould comprised of masses of spores, which mostly become air-borne. Botrytis can affect plants at different stages of their life from seeds, bulbs and cuttings through to mature plants.
