Imagine what our trees are going through with an average of less than .2" of rain in the months of July and August for the past 5-6 years.
I've been following this thread all year. It's neat to see other folks contributions.Hi @JbTech That's a food amount of rain. It seems like the whole US is suffering. Also nice to "see a new face" in the Gardening Forum. Hope you stick around.
We had some rain last night and this morning. Supposed to get more this afternoon...maybe 1 inch in total. We haven't seen any significant rain here in well over a month other than an errant sprinkle. There are trees that are dropping leaves already without turning colors...just dead.

I should have planted a second crop of cucumbers in July. The huge greenhouse cucumber plant is getting attacked by something that is stripping the surface of the stems and the skin of some of the cukes. It is having trouble staying hydrated because of this and wilting during the day. It's a sad sight, this has been a prolific bearer of dozens of grade A cukes. Inspection is not showing up the culprit.My garden is like most others. Odd year / cooler temps have Maters just beginning to ripen. Cherry Tomatoes are just about finished. Cucumbers have been doing well. On my second planting of those.
Sorry to hear this. Cukes are so vulnerable to so many pests and problems. Mine were a big disappointment this year.I should have planted a second crop of cucumbers in July.

Has anyone had this problem?

I'd love some rain! We need it pretty badly.
My cuke stems look very much like yours. Very frustrating to have plenty of blossoms and see the plant die off early. My winter squash plants also suffer from grubs that burrow into the stem at ground level and feast on the inside slowly killing the plant. Last year while pulling the plants I cut into the stem and found the culprit, white grubs.I should have planted a second crop of cucumbers in July.

Squash Vine Borers. Ugh. They have killed every single one of my zucchini plants this year so far, except the one that I’ve been growing inside until recently and just transplanted into the garden.My cuke stems look very much like yours.

My stems look like yours, but only grubs I have seen were always near the base of the stem.Does the squash borer chew up stems of the plant like this?
The cukes are actually doing better than I have had in a few years. No damage on the skins at all. In the past my plants have been near dead this time of the year, this is them today.Squash Vine Borers. Ugh.

I have a Seminole Pumpkin vine growing, and I can see where they’ve gotten into it, but so far it’s surviving. The Moschata species (butternut squash and Seminole Pumpkin and others) are supposed to be a little more resistant because they have solid stems instead of hollow, but I have so much SVB pressure down here in Texas, that nothing stands for long.
Maybe because I keep persisting in trying to grow squashes, I haven’t seen them get into my cucumbers. @begreen, the stem on your photo did remind me a bit of borer damage, but I didn’t see an actual hole into the stem. Usually one can find that and see sawdust-looking frass from their excavations that has been pushed out of the stem.
Did you say that this pest is actually stripping the skin off the cucumber fruits themselves? Do you have a photo of that? I don’t have any good ideas of what it might be; I’d just be interested in seeing what that damage looks like.
On a happier note, we got rain! About half an inch this afternoon/evening. There’s a lull now, but we have the possibility of more overnight. We also have chances for isolated or scattered storms tomorrow into Wednesday. This is huge for us. I’m so thankful.
Do the grubs come out at night? Otherwise, how do they strip up the stems so high?My stems look like yours, but only grubs I have seen were always near the base of the stem.
Thanks. I will read up on these links. I sprayed the plants with neem oil and spinosad twice. Hope that helps.My squash vine borer damage looks like this. It looks similar, but I don’t think it’s the same. The borers burrow into the vine and kill it from the inside out. They don’t strip skin off the outside. I really think @woodey ’s description of the grub is the Squash Vine Borer, and geographically those don’t seem to be your culprit, @begreen. Because I trellis vines, this damage is actually around my eye level. Borers do like to attack the stem right where it comes of of the ground, but they’ll attack other spots as well. The get my zucchini right at the base, though, so that it rots off right there.

I found an article (from Canada) that shows Striped cucumber beetle damage on a cucumber fruit, and if you look closely at the leading picture, you can see how the vine is stripped a bit, too. Your descriptions seem to fit that type of damage. In the second paragraph the describes the larvae “girdling” stems, which sound like they come from the outside. At the same time, I’ve read of them tunneling through the stem and killing them that way, so I’m not really sure of the mechanism.

@begreen, have you sent pictures to your local extension agent?
I got another 6 inches of water into the pond (about 8-10 inches to go) before the well quit. We have to let the well "rest" for an hour or so, so we can both take showers after working. I decided not to water the gardens since they say we may get a thunderstorm later. If we don't, I'll water first thing tomorrow morning. We also got some more wood chips down in the FF. We've almost used up the 10 cubic yards we got last Friday. Time to order another 10 cubic yards.
