Good morning Professional.
I have a very old apple tree that I have been trimming and spraying for 20 years. The tree is much older. During the last 2 years some of the tree has been losing leaves and branches. I have included pictures of a branch that is failing. I have also included pictures of the tree in question. I need help in correcting this issue. Please let me know what I can do.
Thank you

Hello,
Based on what I see in your image, you could have some dieback due to canker on the branches. It looks like a lot of pruning has been done where the dieback is happening. Dieback on apple tree branches can be a sign of canker diseases, which are often caused by fungal pathogens. The symptoms include brown lesions on the branches, and the wood underneath these lesions may appear reddish-brown and water-soaked. Canker is often caused by fungi or bacteria that enter the tree through wounds, which can include pruning cuts.
Can you follow the failing branch (that you mentioned) and let me know if you see any cracks? Let me know what you see when it meets the trunk of the apple tree
PLEASE LET ME KNOW - THANKS!
Consulting a local arborist for a more precise onsite diagnosis and treatment plan might be worthwhile. They can provide guidance based on your area's specific conditions and pathogens. To find an arborist in your Zip Code, go to this link:
