Anyone use 10% milk/90% water for spraying for powdery mildew?

I have some PM and used some neem. I may try milk. Please note this is cow's milk.

Milk
The newest organic control for powdery mildew is milk. In 1999, Brazilian scientist Wagner Bettiol reported excellent control of the fungus on greenhouse-grown zucchini using fresh cow’s milk diluted with water to a 10% solution. An Australian researcher, Peter Crisp, experimented with milk on roses and wine grapes - which get powdery mildew from different organisms. Crisp found that in most cases the 10% milk solution worked as well as the leading synthetic fungicide and as well as sulfur.
According to an article in Science News, the results have been proven in the field by grape growers. But there is some concern than using any product, even milk, repeatedly may allow the fungal organisms to develop resistance. So the current recommendation is to spray for powdery mildew every week, but alternate between remedies. And there are plenty of other recipes from which to choose.

I've used Milk. Not my preferred PM annihilator, but it works.

Use non-fat. The fat will remain after evap, will stink. Also, organic is best. No hormones/pesticides through the feed and lower bacterial count.

Thanks. May I ask - What is your preferred PM annihilator?

From wine growers, I've heard it is specifically the milk whey that they use, not just off-the-shelf milk.

I strongly prefer GreenCure. You can get if from Amazon, or possibly locally if you have a decent hydro store around you. Good luck -- if you catch it early and control your airflow and humidity, you can beat PM.
