Can I send you some powdered sulphur? I really think it will work for you on these rot spots and help keep your pumpkin alive. You can apply directly on these spots and with your fans they will dry right up. Make up a foliar spray of 4 tablespoons per gallon of and hit everything else.

Hey! That's really nice of you. I think I may have a lot of it at my local stores here. Can you send me the link on here and I'll look it up! Thanks so much

I use Safer's Sulphur Dust Fungicide but I don't believe it's available in the USA. I found what I think is a similar product you can get on Amazon in the USA below. The finer the sulphur powder the better, it should be dust like. It's completely safe to use on plants as it's pure sulphur, there doesn't seem to be a toxic level. We have big issues with PM in the Pacific Northwest where I grow and it keeps it at bay if used early and regularly. Because it's a dry powder it's easy to dust on rot spots and it soaks up the nastiness and drys to a crust with a fan. I also make up a foliar solution to spray on everything weekly. Once my pumpkin is over 300 pounds I dust the whole thing from stem to blossom end with a patina of dust. I love the stuff!! Only draw back is if you get on your clothes they smell of sulfur.


From Amazon
Bonide's sulfur fungicide controls common garden diseases and can be used on fruits, veggies, ornamentals, and animals. It's a popular product!

Good luck, I'm rooting for you and that last pumpkin to make it to the Topsfield fair!

Thank you for this! I just got some at a local store so I will try it on a few spots on the plant! It definitely looks like good stuff! I appreciate your recommendation and advice a lot! Best of luck for the remainder of the season!

Let me know how it works for you, I'll keep an eye on this post. The thing I love about pure sulphur dust is that it works against any and all fungal diseases and as far as I know there is no such thing as resistance. The only downside is that it is not systemic - only topical application firstly as dust or foliar as a solution. I am growing the 2388.5 Liggett seed and it is the same size as your Masters and almost the same DAP. Pollination day was June 6th.
