Powdery Mildew? or something else?

Here are my pumpkin plants. They are huge but the fruit turns black and rots away.
I do see White and yellow spots on them. I have sprayed them with funguscides. But I guess they didnt work.

Any idea and help for next year when I try pumpkins again???
Thanks

great pdf, thank you All symtoms are so much alike, I really cant be sure which disease my pumpkins have.

I did do lots of research from google before I posted here, even looking at diseased plants (photos) I really still cant tell. I just thought maybe someone would know by looking at my photos.

Thanks again.

I recognise the black fuzzy fungus on your fruit. It is called Choanephora Fruit Rot. It is caused by the fungus Choanephora cucurbitarum. This fungus can affect both blossoms and fruit. The photo of the small fruit with the wet soft rot is also typical of an early infection, before the fungus has time to sporulate. The best control for this problem is to let things dry out. I have never heard of anyone using a fungicide for it. This pathogen thrives under wet conditions.

I couldn't tell for sure what is up with the leaves. Downy mildew might be a good guess because it is a problem under the same wet conditions as Choanephora. If it is Downy Mildew you should see irregular yellow spots on the tops of the leaves and sometimes a downy like fungus on the bottom of the leaves. This fungus can be white or gray. One of the photos actually looked quite a lot like Powdery Mildew. If you have Powdery Mildew you should see a whitish fungas on both top and bottom leaf surfaces as well as petioles and stems. Maybe you have both! What luck! Hope that helps.

Robin,
Thank you for the information. I think you are right, I think my poor pumpkins have all the above.

Maybe next year I will move them to a more airy place in the yard. Last year I got one pumpkin and something took a big bite out of it and then the plant died.

I'm not having much luck, but I'll keep trying!

or maybe I will just stick with growing tomatoes and peppers!

Thanks again!
