Hi --
I have been trying to control mildew in my garden with a spray of Sodium
bicarbonate (Baking Soda) and dishwashing liquid. Have had no success.
I started with a teaspoon of BS to a quart of water with a few drops of the
liquid soap every four days. I then increased it to 1 tablespoon of BS per
quart with the same 4-day interval and can't seem to stem the spread of mildew
(NJ, Z6).
It started on the Peony, then the Black-Eyed Susans, then Lilacs and then
the Pumpkin vines. (Not yet on Phlox which is unusual). Since it's on both the
Pumpkins and the flowers I might have both Downy and Powdery Mildew.
Anyone have a different home remedy that works? Or a different mixture
of the BS and soap that works?
Thanks (NJ,Z6)

Bicarbonate of soda is alkaline, which does little to inhibit
fungus (including mildew). You need an acid. Try vinegar.

I use a chemical fungicide.
