My zucchini plants got covered in powdery mildew overnight

I was in my garden in Austin yesterday morning and the leaves looked like they were dusted with flour. I mixed one tablespoon of baking soda with a gallon of water and sprayed them down, which seems to have stopped the spread for now. Has anyone else had luck with a different homemade spray for this?

Honestly I used to swear by the baking soda thing too until I tried a milk spray. One part milk to nine parts water, spray it in the morning sun. Something about the proteins just nukes the mildew way better for me.

Milk spray, huh? Guess @victorhill's zucchini are drinking their breakfast now.

I mean my baking soda spray mostly just made my zucchini taste like science fair volcanoes.
