Dutch Elm disease?

[elby]

Currently working clearing a lot of dead Elm. However there are alot of Elm trees about that have decent indication of still being alive at tips but bark is peeling from main limbs below and look completely unhealthy. Loathe to take them out if actually OK but instinct tells me they're not and may affect surrounding new growth?

 

Do they need to come out?

 

Cheers in advance.

if the disease is present it will get them in the end, seen trees that look perfectly fine but if its there they have to come out to help prevent the spread, by the sound of it if the barks all peeling they are well knackred anyway

If local trees are dead or dying from the efects of Ophiostoma Novo-Ulmi, then it is a safe bet that soon you will have no Elm trees left in that area, not only is the fungus spread by the Scolytus beetle, but also via the xylem vessels in the roots.

One way of confirming a suspected infection is to cut an infected branch cross section and a ring of dark red to brown marking is evident in the wood, these are phenolic deposits that are formed in the xylem vessels and disrupt the transport of water and nutrients to the crown.

The tree is dying from infection and dehydration and death can take between a month to two years depending on the strength of the individual tree

Fungicidal injections have been used to try and control the infection but the application is very complex and can leave the tree open to seccondary infection by other pathogens
