Lots of rain and poor draining soil could have lead to root rot. Each plant responds differently even in similar conditions. Did this plant have a fungus issue? If not then why use Daconil? I'm not sure if that plant will recover. Hopefully someone else may have a better idea of what you got going on.

A bit strange that it's the only one in the patch that is affected. Different plants can react differently to stressors, but to this extent?

Check the base of the stem and top of the roots for damage or some sort.

Did you happen to spray this specific plant with Neem in full sun?

I don't know where you're located, but any chance you got a light frost? I'd expect the other plants to look the same though.

Unless you're treating an existing bug or fungus issue, I'd hold-off on the various sprays.

Hi isgen,

No frost here, I'm Central Texas. When I have applied Neem oil, it's always been at dusk when there is no direct sun.

This is really odd to me. I'm pretty sure this is a Tabasco plant. I have one other located a few feet away, but still in the same patch. It is also suffering the same problem. The cayenne, habenero, and jalapeno in the same patch look great, and I hope they stay that way.

I dug off as much soil as I could to get a good view of the base and roots. I really don't know much about what to look for with roots, but they look ok.

They have been such strong plants and big producers, and their peppers are great, it stinks to see them obviously suffering. I don't see any indications of bugs.

And also for the other poster, the only reason I did apply daconil was due to some tomato plants located in another part showing odd behavior on their leaves that the neem oil did not solve. I figured may as well just treat all plants.

Thanks again for any help.

The stem and root tops look fine. I figured it was a Tabasco pepper too.

About your getting no frost, duh, I should have figure out when you mentioned Harvey!

Maybe this variety truly is more sensitive to over watering than the others around. I guess leave it be for now and see what happens. I hope they recover and your other plants keep doing well!

Thanks for taking a look isgen.

That's about all I can figure out what to do with it as well, just leave it be. I suppose I'll try to stop water to it for a bit, although being in a patch with expansive roots might not be totally plausable. I've already been limiting it more then others.

Thanks for the help.

As an update, nothing seems to be helping it. I have another thread on some tomato plant problems, and it was thought maybe I had aphids, but I don't see signs on these Tabasco plants like I do a tomato plant.

Also have a preying mantis hanging around the pepper plants. Hopefully it's helpful.
