Good evening, Growers!
I received these images from Scott Glenn on Tuesday, August 14th.
As you can see, it helps to do a good job on one's mound. The results speak for themselves.
You'll note that Scott's having a powdery mildew issue, which is normal, as the vine begins to age. Powdery mildew is a fungus common to growers in coastal areas, and where heat and humidity are common. Powdery mildew particularly likes squash and pumpkin vines and is very common on roses.
The cure? I suggest trying GreenCure, the organic fungicide developed by Ken Horst at my alma mater, Cornell University, (and Pumpkinmania! strategic sponsor.) It's available at Orange County Farm Supply, Cedros Gardens, and Island View Nursery for those growers in Ventura and Santa Barbara counties. Be sure to mix it well, and cover the top and bottom surfaces of the leaves.
I have had a few requests on how to estimate the weight of a giant pumpkin... Here's the link and instructions from the Big Pumpkins website:

Fortunately, this is still a very useable and reasonably accurate method to estimate the weight of your pumpkin.
Have a great evening!
