This is a picture from my 2007 diary. Have had this happen to many of my plants through the years. Plant and pumpkin growing fine until I notice a section of the leaves turn a bronze color and then to yellow. Pumpkin growth stops and the progression of yellow leaves increases. Plants are then pulled. Any ideas? I'm thinking YVD.

The only sure way to know is to have a tissue test done.

Have a look at the pictures of the 175 Rahe plant, it tested positive for YVD.

Looks like downy mildew?

If the pumpkin stops growing at the initial onset I am going to favor Yellow Vine Decline.
