Young pines with a few dead/browning whorls...?

[Ranger Matt]

Anyone able to shed any light please?

 

these plantation trees are about five years old. Suddenly this year a small percentage have developed a few of these near their tops.

 

thanks for your thoughts

I cannot see the pictures atm but likely candidates with be:

 

Fusarium circinatum

pine wood nematode

Dothistroma Needle Blight

 

Depending where you are and which species, Scots pine is affected by the latter less than corsican or lodge.

 

Another  new to me but lesser evil was mentioned ata recent RFS meeting in Surrey but I didn't note the name

I've seen the pictures now, the blueness of the foliage suggests scots piune?

 

It would be easier if you posted them as jJPEGS rather than PDF.

 

It doesn't look like red band needle blight.

 

Is the dieback only on the current years growth?

 

Have a look at:

I don't know how the link ended at the top of my last post but what I should say is the link came from our local RFS secretary and he identified Diplodia as the problem with scots pine in Surrey.
