Is this Aphid damage on these Mutsu apple leaves?
No, not insect damage. That's more like drought, heat, root issue, salt, etc.
This a tree that was planted last summer. the rest of the tree looks good just say 10% of the leaves are like this.
I noticed on my older winesap, one leaf is like this.
I hope its not fire blight or a virus from a leafhopper.
I know it is not salt, but it could be dry so I will put the water to it. I have never lost a tree before so I sure hope this is not a loosing battle.
Thanks for the replies.
I also vote for environmental. Planted last year doesn't guarantee a vigorous and extensive root system.
Bumping up this thread.
Necrotic Leaf Blotch is what it appears to be. I just started a new thread title called GOLDEN DELICIOUS NECROTIC LEAF BLOTCH to explain it.
Guys thanks for all of the replies. You were right the tree was under stress.
