Bummer. I’ve kept peaches, an appricot and a plum going after bacterial canker but it takes a few years to get on the other side of it. Maximum strength copper applications with sticker after leaf drop and as frequently as allowed. I don’t bother with copper during the season since it burns the leaves at far lower concentrations than will help with the bac canker.
I also diluted water based latex paint and mixed in copper and painted the trees. Don’t know if that helped though
Good luck!
Looking for some help identifying what is going on with my apple/pear trees. It’s pretty widespread across both sides of my orchard, mainly on the newest shoots but’s also on some older leaves. It’s generally an upward cupping of the leaves and I see some purpleish hue to the underside margins of the leaves. Is it mites? Nutrient deficiency of some kind? It’s affecting both apples and pears. I’ve also seen it on my neighbors trees.
Looks like stress due to drought to me. Did you poke a finger into the soil to check the moisture level?
Yes, it has been pretty dry, but I have everything mulched. I check it daily and it has remained moist.
I’m assuming this is June Beetle* damage since I found a pile of them hanging out nearby:
Can someone confirm? I have lots of branches where the leaves are just gone and some of these full of holes are nearby on the ground.
Plan to spray for leaf blotch one last time and wasn’t planning on insecticide, but I suppose I am now!
*Well, I quickly found out they’re actually Japanese beetles…
“While Japanese beetles sometimes get lumped in with the June bug term, they are far more destructive than the other listed beetles. They are a pest during both their larval and adult stages. Their grub forms feed on roots, while in their adult stage, they feast on over 300 crops and flowers. They will chew the tissue between leaf veins, leaving a lace-like skeleton.”
And the Century Farm website says they can kill young apple trees (can confirm).
I noticed this peach tree had dramatically changed from last time I saw it. AI tells me spider mites. I tend to agree- I saw a little brown speck running on the underside of a leaf. Is this salvageable? Does it need chemicals to treat? (Second photo is underside of leaf)
Those are Japanese Beetles. I have a trap out a good 200+ feet from anything I care about. The trap works best for your benefit if a portion of your beetles have been parasitized by the Winsome Fly (Istocheta aldrichi) and you are going to overwinter the carcasses somewhere they can remain undisturbed all the way into next summer in order that the new parasites can emerge.
In your photos none are parasitized and your damage is consistent with Japanese beetles.
