Gray mold rot

Mold, also spelled mould, in biology, a conspicuous mass of mycelium (masses of
vegetative filaments, or hyphae) and fruiting structures produced by
various fungi (kingdom Fungi). Fungi of the
genera Aspergillus, Penicillium, and Rhizopus form mold and are associated with
food spoilage and plant diseases.

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. It can be expected at any time of year.

It is common on apples, grapes, strawberries, blackberries, raspberries,
gooseberries, beans, cucumber, courgettes, lettuce and tomatoes. It is also a
problem for plants grown under glass, where conditions can be humid and
overcrowded. It will
infect Chrysanthemum, Cyclamen, Pelargonium, Primula and, in fact, most
ornamental plants.
Symptoms
You may see the following symptoms:

 Under humid conditions fuzzy grey-brown mould grows on decaying buds,
leaves, flowers or fruit

 If humidity is low, infections may be contained within discrete spots, but if it is
high they can spread rapidly

 Above-ground parts of many plants, particularly buds and flowers, shrivel and
die

 Small black seed-like structures form in infected material (these are often
overlooked)
