No. The recent outbreak of Dutch elm disease was from timber

I have heard, sometimes last year, that they have recently found, 60
years later, a disease coming from the wood which made the american's
soldiers canteen box? This is apparently keeling many trees in Provence
- and spreading.

Dutch horse chestnut disease next. 30% of Dutch horse chestnuts are
sick.

A lot, if not most from my observations, of horse chestnut trees round
here (London and suburbs) have been suffering badly from the horse
chestnut leaf mining moth for the last couple of years. Hopefully the
rather colder winter may kill off some of the overwintering pupae???

Is Dutch horse chestnut disease something else again? It doesn't seem to
be mentioned in Pests, Diseases & Disorders of Garden Plants. Perhaps
because it hasn't reached us yet.
