Help needed! Viral Wilt or TSWV?

[Sandhillstiger]

Hello everyone. I'm new to this site and need some help identifying this issue. I have over 100 heirloom plants, with atleast 25 varieties planted. So far, I replaced nearly 20 plants with issues below. I have pulled and destroyed every plant. I know off hand that my Black From Tula (all), Ananas Noir, Borgo Cellano, Green Zebra, Black Brandywine, Stutzman Black, Eva Purple Ball, Paul Robeson, Berkeley Tie Dye, Pineapple, German Pink, and Jubilee have been infected with something. I have checked for nematodes but the roots look fine. I'm located in the midlands of South Carolina and the growing conditions have been ideal over the past month. We've received adequate rainfall and the nightly temperatures have yet to get over 70 degrees. Any help would ben greatly appreciated! Thanks.
