My guess would have to be that one side gets more sunlight than the other.

Hey Scaner, You have yo give more info then that. Are you talking secondaries on the left side versus the right side. Or half of all the leaves are yellow, or the half of the plant near the stump or half of the plant towards the tip...you gotta give more info to get any replies. These guys will help just need to know what the problem is! Grow em big! Chuck

there are three vines on this pumpkin, all start at the stump. the leaves on only one vine are yellow. the other vines are fine leaves are 3' tall and 22" across one had a pumpkin on it 72" and quit growing and shriveled up,the other has one 98" and quit about a week ago.

Wow scaner thats sounds strange, Did you check the one that shriveled up for cracks in the stem or blossom end. Since your growing three mains off one stump All three are getting the same amount of water, and soil conditions are the same. How has the heat been the 98" one might be slowed by that. The yellow vine has been yellow since the beginning or has there been a progression. This sounds like one for the big guys. I would probably think about removing the yellow vine and hope that the extra juice goes towards the good vines. just a newbie so wait for the big guys to chime in...

mosaic virus can also yellow up a leaf. Chuck

You might want to check for a vine borer entry hole on that yellowing vine. I had that happen too many times in the past. Good luck!

Alexsdad, I was checking out your link and it looks like I might have a touch of Anthracnose. I thought leaves were just getting old and dying, but the pictures look a lot like my leaves. Any thoughts on what I might do to confirm this, or treat this?

Anthracnose will spread to other plants slowly. Usually on rain splatter or by carrying water from infected plants on your clothes to a new area. The Bean stalks that started mine was touching a pumpkin plant and it now has the yellowing leaves. Unfortunately there is no cure...you can slow the spread but anything that is not pollenated already is pretty much done. The other thing is it is soil born and the recommendation is a three year rotation of the patch. one year growing two years off of vining cucurbits. Also destruction of the plant debris at years end. Don't turn it in remove and don't compost. At years end I'm gonna get a tissue sample done to determine/confirm the disease and find out what nutrients are deficient in the plant.

Friday I'll be taking some leave samples to the Cornell co-op and they will be checking to see if I have a problem, or if it's just old leaves. Thanks for the help...
