Default Can you identify this?

About 3 days ago, two of my plants (DLH and Olive Hill) started getting black leaves at the top of the plant, and only on these two. I am losing some leaves due to this, and I'm afraid it may spread around my patch. Any ideas on what it is, and methods to eradicate it? Thanks!

Darin

Looks like spotted wilt virus. I am so sorry. Do you have thrips? The differential would be grey mold, but those spots all throughout the leaf tell me not grey mold. It can spread to other plants from the thrips too. Viruses aren't curable.
Maybe someone else here thinks it is something different?

Oh no. Is this soil-borne, or leaf borne? If I cut off all affected leaves, can the plants be saved?

Leaf borne, and not likely saveable. The virus is throughout by the time you see symptoms.

Oh no. I don't think I have thrips, but I'll read up on those and check. In the meantime, I will top off all affected stems and hope to get healthy suckering from below. If the plants are gone already, then I will yank them.

Everything else looks fantastic. I'm just following a routine maintenance of Neem and Daconil.

Thanks Marsha- you have always been so helpful to me

After some reading, it appears the best treatment for Spotted Leaf Virus is to yank the plant immediately, and hope that the whole garden isn't infected. This indeed sucks.

Thanks

Marsha, If it were TSWV there should be spots on the green too...right?

Darin, you haven't been spraying too heavy a mix or in the sun have you?

I was just thinking it sorta looks like chemical burn.

I've not had to deal with TSWV before to know what that looks like though.

Ray- good question. I only spray at dusk, or usually at the end of the day after a good rain. Let me take some more pictures to help everyone.

Here are a few more pictures. I have now identified three plants with this- DLH, Olive Hill, and Rebel Yell. One Rebel Yell next to the infected plant looks just fine. I have found no evidence of thrips yet.

Thanks to everyone

Any chance this could be black mold?

Yes if advanced enough, but if he caught this earlier, not all the leaves would show it. I think if it was a spray burn, there would be affected stems and most if not all the leaves too.
Darin, what are you spraying with? I really hope this is chemical burn. Mold, not the right pattern for it, no spores that I can see when I expand the photo.

I just spray with Daconil and Neem, every few weeks or so, and not usually at the top of the plants. No, this appears to be TSWV for sure. I just removed all of the tomatoes for premature ripening, and am about to pull these three plants. It's OK- I have 25 others..

Thanks!

RIP Olive Hill, DLH, and Rebel Yell. Hopefully it ends HERE. Thanks to all for your help. Maybe some of these little greenies will have a little flavor when they are ripe. Olive Hill on left, DLH on right.
