Oh well case closed then I guess. Why bother investigating any of the other possibilities or looking for supporting evidence for your diagnosis...

No need for the sarcasm Of course it'll be looked at far more deeply that just an article Was just saying. Can I have my head back?!

email from FC PHSI today re these trees:

 

 

 

Dear ***

 

Your instincts were right and the two trees in Mr & Mrs *** garden tested positive for DNA of P.lateralis, but they could not get a culture to grow from the samples that were taken. I think this is quite common as after the Phytophthora has killed the cells other fungi quickly come in behind and exploit the dead tissue.

 

Bit of a mystery how the trees became infected and I have had a brief look around the area and could not see any obvious sources of infection in the near neighbourhood and the FC did fly over the area in September as well and didn’t pick up any obvious dead trees.

 

The method of spread is poorly understood but is thought to be mainly through soil, associated water and also possibly through the air.

 

A notice has been served on Mr, Mrs *** to the effect that no Chamaecyparis sp.are to be planted within 4 m of the stumps for the next three years and soil disturbance is to be minimised; if trees are to be planted PHSI are to be consulted.

 

Thank you for reporting the trees as it helps to build up a national picture of what is happening (most P.lateralis so far found has been in Northern Ireland, Scotland and north of England) although there was the case in Plymouth.

 

If you come across any other symptomatic trees we would be grateful to hear of them and it highlights the need for good biosecurity as the phytophthtoras are easy to transport on equipment and footwear.

 

I have also attached some links to general information on tree issues that could be of interest.

This a link to posters for different parts of the plants industry from gardens open to the public, nurseries producing plants to the general public walking in the woods/forestry contractors

Lastly this is the link to the Forestry Commission information that is more targeted at trees/forests

If you have any queries don’t hesitate to get in contact and hope you have a good Christmas and New Year.
