Hi, It's really hard to help you determine what happened based on that picture and what you've written.

If I had 59 plants that all recieved the same care I would defenitly think something is wrong.

Are the three that wilted close together?

Have you or a nieghbor sprayed any herbicide lately?

I don't think I need to tell you this, but if watering doesn't help within a couple of hours pull them up. Enjoy the other 56.

Wish I could help more.

Look's like nematodes may be in the root system and are shutting the plants watering system down! As you have many other plants I would remove it just in case of Fusarium or Spotted Tomato wilt disease. I have been fighting wilt problems that look exactly like your pics and have finally won the battle. Half of my garden is in solarization now and next year I will do the other half. It's my understanding that nematodes can cause the wilts or vice verse.LOL-Gary

I have the same thing happening to my tomatos, too!!!!!! It started with one plant and I pulled it up and now within 2 days another plant is totally wilted. It's not because of lack of water and there are no apparent spots on the leaves, etc. Just looks pathetically wilted. What can be used to treat the ground, plants, etc??? I've had this problem for the last 4 years with my tomato plants. I've rotated crops, etc. Still the same OLD PROBLEM!!!!!

Rapid wilting of plants when they need no water, accompanied by NO change in foliage color can mean one thing, while more gradual wilting with leaves turning yellow then brown then dying can mean other things.

And in the posts above that's what I'm reading, so not all your problems are the same and thus really deserve to be in a separate thread to make it easier to discuss, I would think.

Root Knot Nematodes, for instance are found in very few geographic areas.

I'm running out of time here and will continue addressing the problem posted by desert gent tomorrow.
