Can anyone tell me what the rates are that I use for mixing water and milk for a powdery mildew spray? I'm assuming the rates remain the same for preventative vs full scale onslaught? Also, do you use a spreader sticker with that?

Thanks, Betsy

The Mad Scientist (well respected Matt D) advises 40-60% and with whole milk so it sticks better. I read 30% somewhere outside this site also and can't remember what the reasoning was. I have been alternating 33% and 50% and no PM yet. Good luck.

I use 50% whole milk, raw if you have a local source, and blend in a spoon of live culture yogurt just before spraying; here in steamy hot SE Texas I have no pm problems at all. Works better as a preventative by colonizing the leaf first, not allowing pm to start, but still has benefits later

Could you use goat milk?

I am using horse milk this year, as I have a plentiful supply. Also it tastes like sh**

how does milk compare to neem oil extract?

I use a ratio of 1 part 2% milk to 9 parts water. I have been using that for more than 5 years and have never had powdery mildew. If you already have it, milk is not going to help you.

Brad, last year I had used a similar mixture (1 part 1.5% milk and 9 parts water) and I used it every two weeks from August 22nd on in a fortnightly manner. In August there was already some PM on some of the leaves, and of course the milk/water did not remove that stuff, but I noticed that PM didn´t spread any further (at least the milk spray did significantly slow down the PM growth). This might be interesting for those of you who want to grow AGs without heavy duty fungicides and have already found some spots of PM.
