Is that blight?

If you mean the plants going black and rotting then yes, it's most likely
the cause. Some of the fruit may look ok but it will probably have blight
also and rot as it ripens.
Dig up and burn it all or dump it, do not leave anything behind.

I've sprayed ours with Bordeaux Mixture to ward off the blight but then we
also have only grown blight resistant varieties this year because I'm sick
of wasting all that effort.
