Cucurbit Disease and Pest resistance

Moschata (butternut) and mixta (cushaw) are very resitant to SVB in my area. My goal this year is to find the best disease and pest resistant varieties for my area. Downy Mildew is a big problem for me and most every common variety of winter and summer squash and cucumbers will eventually be killed by it. I found a company that specializes in DM resistant cucurbits and ordered some seed (In addition to the 8-10 varieties that I had on hand!). If they work as claimed I will bag some females for seed. Got my fingers crossed, one that was ordered was a butternut/Seminole cross looks and tastes like a butternut, but resists mildew like the Seminole. Most of my squash are heirlooms, but if an OP hybrid works I will be fine with it. It seems like any of the squash that were bred/developed in the deep south, Caribbean and Central America would have to be DM tolerant. My goal is to beat the disease with variety as opposed to treatment, guess I'll wait for July and see.

Please post your results. I'll be watching.

You may want to try varieties from Thailand. I've grown them many times, they thrive in hot,humid weather. www.rareseeds.com has a great selection. Where did you get your seeds?

Most of my squash came from Bakers Creek (Rareseeds.com), but I found the butternut I talked about above from Seedwise.com, and I also bought a new cucumber variety that is downy mildew resistant. It came from the Seedwise as well and was developed by Cornell University. I think it was called DM264. Here is their link: https://www.seedwise.com.

Another neat company I found is here:

They have a c. maxima (Zappallo de Tronco) that is used as a summer squash that I will also try.

Terroir is a good company.
