Is there any efficient way?

My blueberry tree is suffering from canker. I’ve been cutting off the parts contaminated, but every now and then it appears again, is there any efficient way to eliminate the disease?

It's apparently caused by a fungus and is quite widespread in the USA and Canada but not yet in the UK. There seems to be no treatment other than cutting out and burning affected stems. You need strilised secateurs and to cut 6 to 8 inches below the canker but even then it's probably a losing battle.

This is a bit more hopeful:

It’s a losing battle! I’ve been doing all that you mentioned, but still, it appears every now and then. 😭
And it’s heartbreaking ❤️‍🩹 to see it dying slowly.

Get rid then and buy a resistant variety.

Do it asap before the spores spread to neighbouring plants, especially neighbours' plants.

fortunately my neighbours have no plants.

Is there any efficient way?
