Tswv is hitting me hard. I've been spraying every week with alternating insecticides plus have 12 yellow sticky traps that I have replaced for the second time. I've pulled at least 30 plants with about 20 plants left. Is it safe to use saved seed? I received some of Carolyn's last seed. I love Dikovinka and saved some of the first ripe tomato seeds. Inshir Rozovyi and Viva so far look okay but still green. I ordered and tried Slava this year and it seems to withstanding the onslaught. Mountain Magic didn't make it.

I've got a couple of more bells that need pulling due to TSWV after pulling one last week. I'm not worried about the tomatoes any more because most of them are pretty worn out and near the end unless I want to spend a lot of time and effort getting them back to making a few tomatoes. TSWV has not been too much of a problem with my tomatoes the past month because I have been spraying them regularly for spider mites and I think it has lessened the thrips infecting them.

It sure looks like TSWV. Are the new blooms dying or dead? Is the top new growth looking like it is burned around the edges of the leaves?

If all your plants have it then there is no need to pull the plants if they have some healthy looking tomatoes on them. Let them start to ripen and by then the plants will probably start dying or wilting from the top. If what you have is TSWV it is very rare for a plant to continue producing new fruit although I have had it happen to a few and they held on for months with very slow production and smaller fruit; but usually it is only a matter of a few weeks at most before the plant starts dying after showing the rust like appearance in the leaves.

Thank you for the explanation. I had cut the top to prevent it from spreading but it did not work

Once the plant is infected there isn't anything that I have tried or anything that I have heard of that slows it down or stops it. I have tried both removing plants immediately upon spotting the disease and leaving them in place until they die or wilt totally. It doesn't seem to make any difference in whether or not I got more infections on clean plants even the ones right next to each other. It must not spread very easily other than through the thrips that infect the plants initially and there doesn't seem to be any way to stop them from doing so when they show up. TSWV cases seem to come in waves at different times with usually the heaviest infestation early in the season and with lighter cases popping up from time to time over the whole season but that could just be my experience with the disease and it also could be my location.

The only effective thing I have found that has so far assured me of a productive season despite the ravages of TSWV is to plant far more tomatoes and peppers than I need and just remove the sick ones when it strikes. It can leave some very gappy rows at times of heavy or frequent infections of TSWV and at other times I end up with way more tomatoes than we can deal with in seasons where TSWV is not as pervasive as usual down here.
