I have two plants that are reaching pollination stage. Both have received the same exact treatments. One, a Steil, is growing great and strong. The other is a 2006 Geddes, and for about 2 weeks has been declining. The Geddes first exhibited weak leaf stalks. While everything was green and growing great, a light rain would cause leaf stalks to bend in half and the leaf would then of course collapse to the ground. Shortly after noticing this, the main vine began turning yellowish at the growing end. I am now noting that the stalks are turning very light green, and some leaves have a manganese deficiency look to them.I have had both plants on a imidacloprid (Bayer Advanced), Immunox regime from the get go. I have seen one single squash bug, which I killed, but otherwise have found minuscule insect damage/signs. I've switched over to Daconil just to change things up on the fungicide/disease control front, but so far I'm stumped as to what could be the problem. This is new ground which has never seen a garden. Could this be a manganese issue?

You might have a nutrient deficiency; did you have a soil test? Yellow vines aren't necessarily a problem. Lots of plants that put out orange pumpkins have yellow vines. A couple leaves bending over might not be trouble either. Might have been a gust of wind or a critter running through the plant.

The plant has been green and healthy until the last couple weeks. The vine changed color within a day from green to greenish yellow. The leaf stalks simply can barely support the weight of the leaves, and the leaves arent overly large. All it takes is a little water on the leaf to cause the stalk to bend in half. Today, after a night of heavy rains, I didnt note too much more stalk breakage. The vine seems less yellow, and growth is still rapid. I did switch up ferts to emphasize Potassium along with switching to Daconil. I'm considering some micronutrients as well.

No soil test. This was done on a whim this time. If it goes decent considering I am in NC and the environment is fairly tough, I'll plan on a more serious go of it next year.
