Pests & Diseases
and leaves. Control: Biological control such as hoverflies,
ladybirds and lacewings.
Birds - Damage to plants,
eaten fruit crops. Control: Fruit cages or mesh and
Botrytis - Brown spots,
which are followed by a furry grey mould. The cause of
the disease is too much dampness in cool conditions.
Prevention rather than cure! Avoid over watering, ensure
decent air circulation, cut down on fertiliser use. If
infection occurs remove affected areas and burn or
discard. Do not compost.
Powdery Mildew - Light
grey powdery patches on the leaves, shoots and flowers.
Non developing, discoloured flowers. Causes and
treatment as with botrytis above.
Red Spider Mites - Speckling
and bronzing of the leaves. Usually found in greenhouses
as they thrive in warm and dry climates. Control: Spray underside
of leaves with water to keep plant moist and turn down
the temperature slightly.
Slugs - Damage to plants.
Nematodes are the best way to control a slug
infestation. Barriers around the plants such as crushed
egg shells, sand, soot and ash work temporarily but need
replacing often. Chemical controls are on offer
but make sure you choose those that do not affect the
plants or wildlife. 'Slug Stoppa
is ideal for this purpose.
Viruses - There are many
individual viruses that affect strawberry plants. By
buying a registered disease free, disease resistant
plant you should ensure that the plant will not be
infected in the future. If however something does not
seem quite right it is important to research exactly
what you may have and if it will affect any of your
other plants. If the virus is specifically attracted to
strawberry plants it may be necessary to destroy and
start again. It may also be useful to find out exactly
where the virus originated from.
