Antitranspirant as a mite and fungal spray

[FreyaFL]

I seem to have broad mites on my lone bell pepper plant. Besides ordering expensive miticides, which I don't want to do, in searching online I came across a site that said using an antitranspirant will get rid of these (and other egg/larval insects) very quickly and that it is biodegradeable and non-toxic. I ended up reading an article by the Arizona Cooperative Extension validating this (an article in their "least toxic pest management alternative" section) along with saying how it can help control powdery mildew and other fungal problems (powdery mildew kills all my cucurbits...it's sad.) So, has anyone used this stuff before? My pepper plant doesn't have any fruit atm, and probably won't if I can't get the broad mites under control. And, if you have used it, did it work well? What brand? Where did you buy it? Thanks!
