Are both affected? Marketmore should be ok if it's wilt spread by the
beetles. I assume the heirloom is not resistant. Temps have been down due to
the excessive rain which may also be affecting their growth. The heavy rains
in heavy soil may also be promoting root rot. It's unusual for vine borer to
be in cukes but it might during heavy rainy seasons. Check for frass, or
sawdust nearby and you might find a borer hole. Slice vine lengthwise until
you find the borer and destroy it. It's probably one of those 3 things -
borer, wilt, or root rot.

I'm growing them outside in good soil. I live in the NE US so it has been
extremely wet. However nothing else in the garden has been effected
negatively by the weather. Cuke beetles probably aren't the problem as
the
leaves are not being eaten, but they are present in small numbers. I am
growing poona kheera(an heirloom variety, and marketmore.

Not enough info. Where are you growing? Is it relatively hot, cold, wet,
dry, good soil, sand, clay, pots, buggy (evidence of cuke beetles?),
wilt-resistant seed? No doctor could diagnose "Well, he was fine until
he
turned 25. Then he got sickly and died."

My cuke plants are dying. The grew nicely until they began to produce
cukes
and then they began to wilt and turn yellow and die. Any help would
be
appreciated.
