Grey mould Botrytis symptoms on rose petal

---

Grey mould is a disease caused by the fungus Botrytis cinerea. It normally enters through a wound or infects plants under stress, but will infect healthy plants as well, especially under humid conditions. On roses grey mould is primarily a disease of the flowers and buds, leaves are infrequently attacked. Infected buds rot on the stem and infection may progress down the stem. On petals botrytis cineria produces pink rings.
