Comments on: Horse Chestnut disease – an update http://www.woodlands.co.uk/blog/flora-and-fauna/horse-chestnut-disease-an-update/ A blog about woodland activities, outdoor skills and conservation Wed, 08 Feb 2012 15:04:02 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Joanna Weldon http://www.woodlands.co.uk/blog/flora-and-fauna/horse-chestnut-disease-an-update/comment-page-1/#comment-7838 Joanna Weldon Sun, 28 Aug 2011 10:04:31 +0000 http://www.woodlands.co.uk/blog/?p=985#comment-7838 I notice a lot of Horse chestnuts (August 2011) are being attached from the BOTTOM My trees are very old and are being attacked from the TOP. If an insecticide could be found that killed the moth could it not be sprayed on the ground in the Autumn/Winter so any over-wintering of the moth could be killed off. I care about my trees so I would do it which might help some way towards the overall picture if others who care did it too.

It's now late August and the leaves on both trees are more than 70% brown. What is interesting is that a few trees in our neighbourhood of south-west London have very little moth infestation whereas trees nearby do.

All 4 with the moth and one with moth and bleeding canker. Has anyone found a horse chestnut that has'nt got the moth? I do not believe there are any. How can a moth travel so viriliantly all over the country, it is unreal. It is very upsetting. I am in Leicestershire. What can we do to stop it, if anything?

It is so sad to see this disease on such majestic trees, would like to know very much. thank you. I am wondering if it is possible to save these trees?
