Verticillium Wilt

[Bob Rolfe]

I posted this diseased Acer Brilliantissimum in my front garden a couple of years ago but I didn't get a definitive answer to the identification so with renewed anticipation Im gonna fire this at a larger audience and im also gonna hazard a guess as well of verticillium wilt ...Im not sold but its all I got

 

Anyone else got a better guess

 

 

 

 

 

 

I think its picked up a few lodgers as well due to the species and it being poorly an all lol

You should't give up on people.

 

One simple test to see if its verticillium wilt will be to cut back a section and see if there is any brownish staining inside.

 

One other option is chemical damage, whats the tree near has any spraying or unusaul activity that could have affected it.

 

hope that gives you a clue.

I admit to not really knowing but regarding VW see Verticillium wilt / RHS Gardening Advice

 

But I alos note in Strouts n Winter DoE book 'Diagnosis Ill-health in Trees' he mentions an unexplained condition on A. pseudo. & Brilliantisimum which is described very similar to your photo's illustrating with 'inter-veinal leaf browning'.

 

As 'treefrog' suggests cut back into a branch with affected foliage and see if brown staining is present, a process of elimination.

 

Cheers..

Bob,

Provided it is not Verticillium, the second and third close up look a bit like swollen "blisters" of a mining moth at work, so if you want to follow me on that, try to identify the species with the second half (in English) of : Mining moths on Acer, or if there are any infected Aesculus close by, it could also be Horse chestnut leaf miner (Cameraria ohridella).

If it had verticillium two years ago I reckon it would be a goner by now.

Thanks for getting back to me lads

 

Dont think its moths Fungus mainly due to the fact ive not seen any and the spread of the scorch like marks aint hollowy ive cut a branch up but didnt see the verticullum marking as described by treefrog and if spraying were the culprit more of the plants would of got it

 

not looked at strouts and winter yet but its well puzzled me

this thing starts up soon after the leaves sprout and goes after they leave
