Common and uncommon diseases of fruit trees

I bought and planted this Flavour Queen tree last spring.
This winter I 've noticed this

Does anyone know what it is? Any suggestions?

My guess is that it is grafted on bad (infected) rootstock.

It looks like some kind of canker. It may have come from all of those dead leaves under the tree. Is there any surviving green wood between the rootstock and the scion, or is it completely cut off? If the top of the tree is cut off, you may be able to graft onto one of those suckers-if there is good scion.
Maybe you can try an inarch graft to save it.

Doesn’t it look like fire blight?

I do not wish to be a bearer of bad news but your tree does not look good. In the second pic, it looks like the tree, somehow, has sustained a wound which allowed canker to move in and further damaged the trunk of the tree.

Where is the graft union of the tree? Have you planted the tree deep and buried the graft union?

Could you please take a pic of the graft union and the whole tree?

I have used leaves and ash mulching for the last 10 years and this is only the 2-nd time I have this issue and in both cases I bought trees from the same source. It seems dead on one side, but there is some cambium left on the other side, so assumably it’s still alive.
It is a great idea with an inarch graft. Thanx Nil

The graft union was not in the ground


Don’t know, but I never had any problems with fireblight.

Where are you located?

I have a hard time seeing the graft union but I assume it was the dark portion close to the ground. If there is any shoot coming up above the graft union but below the damage area, I will cut the tree off there.

To me, the extent and the location of the damage is not worth saving this tree. Since it is not bud out yet, you can take scionwood on top to graft to you other peach tree to save the variety.

That is quite a small tree. Did you buy it locally or mail order it?

Peaches does not get fire blight.

I didn’t realize it is peach, I didn’t read it right, I thought it is quince…

A pluot. Stone fruit don’t get fire blight. Canker is more common.

I’m located in Europe, Ukraine.
The branches are very thin for grafting, but I’ll have a shot at it. Thank you for the advice.
It is a mail order.

That much I know,:grinning:

Some can but not often.

I should have said “usually” don’t.

Problem is that
The tree is susceptible to this canker
will probably get it again.
