Insect and Disease Identification Thread

How old were they? I had a peach tree like this. It was kind of wimpy even at 3 years. And the top never woke up this year. I thought borers had got it, since it had some, but the rootstock part above ground is growing now. So I’m wondering if there was some sort of graft failure.

6ish years.

The bottom trunk of your crimson crisp doesn’t look alive (but it could be the pic). The top can be green from stored nutrients, while the bottom is dead, I’ve seen it, not sure what it means.

How do the roots look? What are all the plants around the base?

You should make a thread.

Scott once told me he has some trees that don’t wake up at first or not at all and he said his didn’t ever wake or recover, so I should call it a loss, but we were talking about 1-2 year old peach trees… which is really different

I have 2 apples in 10g containers that didn’t wake up but still scratch green. I’m pretty sure they’re dead. I can’t find any sign of anything wrong, perhaps it’s the same thing, but they were packed in with a lot of other containers that all woke up notmal. Going to examine roots this weekend. How did the roots look on the crimson crisp?

Any losses in such a sluggish activity hurt. Doing so at such a small scale amplifies that feeling. But its part of it all so what can you do. Learn what you can and move forward.

Similar situation to my favorite 4 of last seasons skillcult seedlings. I overwintered them in pots on an upper patio to protect them from mice. All of the ones that i left at ground level are doing well. I’m betting being so far from the moisture of the ground let them dry out more than they should have. Ill take my shortsightedness over disease.

I’m sorry about that. I just checked again and now mine scratch brown. Up rooted then and the roots look totally healthy. No idea what happened. Wish I did so could take steps next winter.

were they on seedling roots or grafted? if so which variety on which root. Looking for any commonality/clue.

All G.214 that I grafted last spring. Galarina, triumph and crimson crisp. Did great last year. The Galarina looked girdled so that one doesn’t count. The other two looked perfectly fine with normal roots. Maybe like you said, it was a watering issue, though I had smaller and larger containers with them make it through fine. And it’s odd that they appeared green and alive and slowly turned brown and dead to scratch over the last month not waking up.

These are feasting on my mandarin tree. It’s a large tree, and the whole tree is covered with them. Last yield was bad, fruits were tiny. It’s a neglected tree. I just pruned it, and gave it a dose of iron sulphate and some NPK. How do I get rid of these insects?

What’s this? It’s on a citrus leaf.

This is exciting. Thank you.

Some, not all, of my asian pears have these red blotches on their leaves; what is it, do I need to worry, etc?

Just found all these eating one of my little gooseberries. Internet says imported currantworm. I am so amazed how quickly pests come out of nowhere and find my new plants. I would be shocked if anyone in my neighborhood has a currant

I was continually picking these off my red currant, and jostaberry last year. I don’t remember what they are called, but they strip the plant in a matter of days. There are probably 20 more you don’t see. :skull:

My chickens liked them… I’d get a container and pick them off until I did not see anymore, or I was tired of it. They come from a tiny white dot of an egg on the underside of the leaves.

Ugh. I’ll be checking twice a day! Thanks for the warning

Forgot to say the eggs wipe off easily if you find them.

That looks like it might be the early stages of pear leaf blister mites.

Too late to treat for them if that’s what it is. All my pear leaves fell off for a couple years till I figured it out and got them under control. I spray with sulfur/oil in fall and again right before bud break now.
