Maybe potassium deficiency of apple?
So far no sign of rust on my service berry which is good.
There are a few bugs though..I got this i think saw fly larvae, some sort of leaf roller. And then what i think might be a wooly aphids. Does anyone have experience with wooly aphids on serviceberry
This is not a reply to anyone, but I know of no other way than to interrupt and rudely post my question. Sorry
Out of 20, one year old grafted persimmons (starting their second year as a graft) , three did the following:
Burst forth this spring, on time, at least six inches of growth.
Then started withering at the top tip. Tip leaves on top fell off. The trunk , at the tip, started shrinking, the wood obviously drying and shrinking and looking dark and dry.
This syndrome moved down the trunk. Both new growth and older yearling wood. I grasp at straws. Sprayed for unseen psyllids. Dug around the roots checking for vole etc. underground damage. Took a dead cat to the graveyard at midnight and swung it over my in-laws grave, ala Tom Sawyer and Huck Finn. All to no avail.
The sapling died to the graft union. New growth sprouted from the root stock on all three. The rootstock is 60 ? chromosome native American.
The three that did this were Saijo-Rossey cross, UKR 21-12, and Mount Roman Kosh
And there was another one of each that didn’t do the above.
So what do you think?
I don’t know anything about these particular varieties but is this a graft known to be compatible? was there swelling at the graft union?
I have read that graft incompatibility often kills the grafted part right after a big flush of growth. And in my very limited experience (I had one die like this), it sounds like yours. I grafted pear onto roadside callery which is known to sometimes have incompatibility issues.

Probably KDS. Some hybrids are susceptible, we don’t really know much about it, search the forum for more info
It took me a few minutes to find that you need to search KSDS: kaki sudden death syndrome.
There are some pictures with leaves that have these little black lines in them:

Surround impeeds the cuircs enough to save most of my fruit from being scarred. Certainly worth it in my opinion.

Is this damage familiar to anyone? Some of the smaller fruitlets look like some critter with teeth bit them in half.
Just for kicks, I dissected one of the damaged fruits to see what’s inside. Looks like the larvae focused mainly the seed part.

Had an american chestnut with blight so I applied a mud pack to it. It’s been wet so I left it on for a week rather than wrap it. I went out there this evening and saw what appears to be ambrosia beetles all over the thinner packed areas. There’s a little bit of sawdust but no “toothpicks” sticking out yet. Do these look like ambrosias?
I squashed as many as I could, but it was getting late so I’ll check again in the morning. I planned to cut the tree in the fall, but I was hoping to get at least some nuts for the first time before I do it. Maybe spraying the mud off will reduce the ethanol “scent”?
I assume they may be there due to the blight moreso than the mud
I suppose, but it had blight all last year and the tree was clear before I packed it. I figured the lack of oxygen in the packed area was causing more stress and ethanol release. Here’s a pic from a few weeks ago.
Either way, I’m just concerned about them moving on to healthy trees if that’s what they are. I’ll probably spray some permethrin on it in the morning.
I’m in the yard and woods a lot and have never seen a sign of them before.
Nine days ago my Napoleon cherry looked like this.
Today it looks like this.
It looks like it’s beyond saving now. But what is wrong with it?
Same thing happened to me on a Stella. It has sprouted below the graft now.
Anyone know what’s going on with this serviceberry? I’ve never seen this happen before. Tree is around 4 years in ground. This is the tree that had nearly all the fruit infested with sawfly larva. As of today, most of the leaves are abruptly yellowing, some of the tree shown in picture below. I have 2 other serviceberries that are healthy. We’ve been in a drought, no overwatering, no new fertilizing…I’m at a loss for what’s going on. It was fertilized at the beginning of spring over 6 weeks ago.

I’d love some help identifying what’s going on with my Honeycrisp trees. I was thinking maybe black rot? I’ve been diligently spraying sulphur all season, so I was thinking not scan. I’m sure I’ve got some diseases and bug damage going on here.
Also, most all of my apples are frost damaged. I’ve seen the frost ring on a lot of them. Is that what’s going on with these? Or is this scab? I didn’t have scab on my fruit last year. Some curc damage too..
Cedar apple rust, I believe. really won’t impact it too much, copper during winter will help but I’d say no use in spraying anything currently, you could probably do immunox if you really wanted it to look pretty but depends how many fruit you have.CAR is basically unavoidable in areas it’s prevalent in but mostly is just cosmetic if your tree is healthy.
Any thoughts as to whether this is rust or nitrogen deficiency? Parfume de September. Neglected in error for 2 years without irrigation and somehow survived. It greened up well after hooking up water, only to now have curled up yellow leaves with brown spots.
So it looks like the ambrosia beetles have made it to another one of my large american chestnuts…except this one is seemingly healthy and blight free.
