The pathogen has a large range of hosts and rapidly develops resistance. Botrytis rot can spread very rapidly to healthy fruit and therefore cause great damage in a short time.
Grey mould [Botrytis cinerea]
Grey mould is found in many crops including: strawberries, blackberries, pomaceous fruit, grape vines, lettuce, vegetable crops, oilseed rape, asparagus, beans, ornamental plants, tobacco and others. Infection can take place during the entire growing period, as well as post-harvest during transport and storage. The fungus is capable of penetrating healthy plant tissues.
Pattern of damage
Mainly rot symptoms are observed on the host plants. On the fruit, sunken-in rotted areas appear, and later the typical gray, dusty fungal lawn (Pictures of different infected crops).
