garden is in.
If it had an external cause, looks like herbicide injury actually, 2.4.D. I don't use herbicides but the affected plants are nearest the edge of the bed, the corner, and my neighbors use it around their porch and ramp. The taller plant is the most affected. Possibility exists that the wind brought me a present..
The other possibility would be fusarium wilt. Since the plant got better, not worse, when I hit it with a lot of water, I don't think it is a fungus.
(in my experience, fire blight and other soil borne funguses get much worse when more water is applied.)
But the photo for this one is picture perfect:
Figure 32. Physiological leafroll
Physiological leafroll
Physiological leafroll occurs when the edges of the leaves roll upward and inward (Figure 32). Sometimes the curling continues until the leaf margins from either side touch or overlap. Some leaves on the plant may not exhibit rolling. Leafroll does not reduce plant growth, yield, or fruit quality. It is believed to result from irregular water supply, and may be intensified following pruning. The symptoms are sometimes temporary, disappearing after a few days, but can persist throughout the growing season
What do you think?

Leafroll Agreed for the leaves, but you have almost a straight streak of damaged plants going thru there...I don't think the fusarium without looking closer at those branches, are the leaves that are yellowing soft or crispy? reminds me some of the early blight, I would pull and burn those yellowing areas...
I also have a straight streak of one heirloom species of tomato, and I'm not sure which one it is. The outer edge was not being watered properly with sprinkler alone, but that inner stripe, well part of that was being watered. The yellowing I think are soft, and just appeared when I left a soaker on for a few hours the other day.
Maybe both Leafroll and fusarium. I planted way more tomatoes than I needed, if I have to pull these out I can, and dispose of carefully. I believe the back row, very healthy, closest to camera, is Arkansas Traveler. The next row I think is Bonnie Best, that would be the sick bunch, and the front row I think are Bradley. All heirloom, all from Annie's. I started from seed, and I did not have tomatoes on that section last year. had a few up under the abelia bush, but that back section where the mothers day tomatoes are has only had grass, weeds, sweet corn and squash. Ever.
May be water damage... tried tamping for soft ground around them? Good luck, I am at the end of my capabilities here...
well, I may be at the end of my capabilities too. I'll play it by ear and see what they do. They are finally moist now anyway. Thank you.
