LAVENDER PEST AND DISEASE
|
|
Lavender has very few pests and diseases. There is a
widely held but unproven theory that lavender prevents diseases in other
plants. The most evidence we have is that it does reduce the amount of
greenfly and white fly. |
PESTS
Lavender is remarkably free from pests. It is occasionally affected by
cuckoo spit (caused by froghoppers / green capsid bug). It is a bit
unsightly but causes no damage at all.
DISEASE
Lavender is also mainly free from pests. The diseases noted below are a
rare occurrence.
Alfa Mosaic Virus is fatal. It can be identified by
yellow areas appearing on the leaves. If left, the leaves will distort
and the plant will eventually die. It is spread by aphid and human
contact. As soon as it is noticed the plant should be dug up and burnt.
Shab (Phomopsis
lavandulae) will also kill lavender plants. Several decades
ago this disease decimated most of the commercially grown crops in
the UK. But it has not been seen for 30 years or more.
