Massaria on the March

[David Humphries]

Large lateral branch with Massaria and another unknown sp at work causing an intense white rot of the core.

Apprentice took out a few Massaria branches from the same tree today, one live one dead.

The live one (lhs disc) presented with very odd desiccation.

Not at all the typical form (rhs disc)

That LHS branch looks very odd. Any pics of the bark on that one?

Very little bark on it Jake, just a thin slither underneath.

You can just make it out at 5 o clock.

 

 

Didn't get a shot, but it's still on the trailer. I'll try and remember tomorrow

Rescued the branch before chipping, very little bark on it.

Left hand disc is from the branch shown below, right hand disc is from another branch.

More Massaria, so up went our apprentice.

 

This one has a very small amount of sap wood still functioning, (2cm stretch at base on cross section image)

How many trees have you found to be infected David?

[David Humphries]

Most of them I think Sean.

 

 

But ofcourse we don't have the proportion of plane populations like the Royal Parks have.

 

Perhaps 5-600 plane trees out of our 20,000 or so total.

Starting to find the disease on bigger and bigger diameter branches.

 

This one directly above an entrance to a secondary school.

Starting to find the disease on bigger and bigger diameter branches.

 

Dysfunction only across a small upper section of the branch but enough to lead to most of the foliage dying.
