When you set out seedlings or plant your seeds water with something like Admire, if you don't mind the use of chemicals. It will kill the larvae before they emerge and start the disease cycle. You must do this immediately and every 10 days until the plants start producing, then stop (10 days before harvest). The beetles you have now are going to be laying eggs all summer and come back with a bang next year (that is if you don't have a super cold winter). Plant less bitter cukes (there are no zukes that are resistant I know of). And be aware resistant doesn't mean they can't get wilt, just less likely. And yes, some years my Diva is taken down by wilt, but it is usually because I was not vigilant with watering. Be aware, that too much insecticide can leave the door open to spidermite infestation...

Have you looked to see if those plants have the Squash Vine Borer?

I had the same thing happen and it was Squash vine borers

It does match the description and the pictures, some vines have completely dried up, and I do have the cucumber beetles, but I'm not seeing the "bacterial slime". I've tried cutting severely affected stems and slightly affected leaves, but I don't see the liquid. I know that doesn't mean it's not bacterial wilt, but there is that. I did plant them a bit late (late May not mid June as recommended), but as seedlings. They could have gotten it at the nursery or after transplanting. It doesn't sound like there is anything I can do at this point except harvest the cucumbers I do get before all my plants succumb. I assume they are still edible (not the brown or yellow ones of course).
