Stephanie, lots of people recommend milk recipes.....hopefully someone will come forward with the Rx that works for them. If I end up with an infestation that I can't rinse away with plain water syringes, I reach for neem oil. Follow the directions....and do not use every day!

I have had good results contr4olling Powdery Mildew using either a mix of 50/50 Fat Free Milk and water or 1 teaspoon of Baking Soda mixed into 1 quart water. The link below is a very good one about controlling Powdery Mildew that I have posted here many times.

Thanks so much!

I read the article you posted and ordered the Serenade product it mentioned. I also have neem oil and I was thinking of using them in conjunction. Fingers crossed, hoping I can save the pumpkin plants!!
