    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.

    Pest Profile

    • Symptoms & Diagnosis

      Occurence

      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).

      Treatment

      Combat

      The control measures depend on the infected crop and the time of the infection.
