Insect and Disease Identification Thread

Those brown recluse bite pictures are… Special. You nurses with your stomachs of steel!

I’ve started stepping on my garden shoes thoroughly before putting them on, glad to see that’s a trick other people use too!

I’m fairly certain I was bitten by a black widow back in my college days. I was drinking in a bar and ended up climbing around in a shed they had out back. Something bit my arm, and the next morning I was sick. I attributed it to being hungover. After four days of dizziness, nausea, and not being able to keep anything down I went to the doctor. My bite had progressed to a silver dollarish spot of necrotized skin… Good ol’ college.

Gosh, yes. sure sounds like it. Those are the symptoms of a Black Widow bite. Good thing about being young and vigorous.

I hope you guy can help to identify sour cherry and possibly the other stone fruit disease.
I grafted sour cherry scions received from ARS this spring. After I received them I put them in 10% bleach for 10 min and then kept them in refrigerator. They looked good. After they were grafted they failed to thrive. They stayed with the green swollen buds for a long time. Then some of them had flowers, but they did not push leaves and they looked alive but stunted. The sour cherries from the other sources which were grafted later outgrew the ones I received from ARS. I started to think that something is wrong with them… The last two days we had plenty of cold rain, everything was soaked. This afternoon I went to look at the grafts and I saw that the young shoots below the grafts had dead leaves, some shoots were dying too, starting from the tip. It looked like the water was running from the grafts to the new growth below spreading the disease. All ARS grafts had necrotic leaves below them. Here are the pictures.


Is it brown rot? If so, beware, the ARS cherry scions spread it.

It’s to early to say but it could be Blossom Blast http://msue.anr.msu.edu/news/bacterial_canker_ice_nucleation_frost_injury_and_blossom_blast_in_sweet_che

Thank you, Clark. But we had no freezing temperature the last two days, the night lows were 44 F. Just a lot of rain. It is probably something else…

We have another thread on this forum

Which is mentioning Moniliose (Brown rot or twig blight). As soon as it gets drier I’ll spray the threes. Is anybody know how to fight it?

When I was dumping my potting mix out of my 10 gallon root pouches last fall I almost put my hand down right on top of a black widow. 2 days later my dad was helping me finish and found two more. I could feel phantom creepy crawlies for the rest of the day. Nothing gives me the heebie heebie like spiders.

Absolutely black widows are dangerous. I bet that did make you feel like that.

Here is damage caused by locust leaf miners. the only fruit I’ve seen them on are my apples. Akane and Williams Pride to be specific. I’ve crushed 4 or 5 of them.

Likely Pear Sawfly (Pear slug) Caliroa cerasi, if yours are darker colored when smaller.

Gummosis? Some gnarly citrus disease.

I think that is a March fly. Thought it was a spider wasp at first, then maybe a robber fly, but March fly seems like a perfect match if the head is the same.

Bibionidae - March Fly. That’s a match. Thanks.

Any idea what is up with this little Crimson Passion Cherry? I have two I received and planted this spring and they are both sick with something. I have more pictures if they would help.

Oz,
You may get more response if you create a new thread asking for help for your bush cherry.

Close up pictures of the leaves and the zoom out pictures of the whole tree and the ground will be helpful, too

Saw this on my almond branch. It looks like a case. It isn’t soft. Good guy? Bad guy?

Sorry it is out of focus - was trying to zoom in. Here is another angle.
