Cucumber plants dying from middle up

Onoahimahi(6 MA)September 5, 2013

Hi - I have 6 cucumber plants in the same location that have been doing fine until recently where 3 of them have basically died from the middle on up to the top. This is shown in the photo where the leaf in the middle of the shot is green yet all the leaves above it are completely dead, and the leaves below it are green. This first occurred in the middle of August so I pulled that plant out. Now two more are doing it. Any idea of what is going on here? They are getting plenty of water and the ones that aren't affected are doing fine and producing cucumbers.

Could it be borers? Check the stems around the point where the dead leaves start and see if there is a larva inside the stem. My grandfather (after cursing! LOL!) would cut a small slit in the stems of his zucchini plants and remove the larva, and the plants continued to flourish.

No sign of borers that I could tell. I have dealt with squash vine borers in zucchini plants - those have larger diameter vines and the grubs are about 14" diameter. I sliced open the cucumber vines and didn't see anything inside. The insides of the healthy parts didn't look significantly different from the dying parts. I did find a few striped cucumber beetles and understand they can cause bacterial wilt. Can wilt kill the plant from the middle up as I am seeing?
