What is the suggested treatment for powdery mildew on indoor propagated mint
which will not render the cutting inedible

MRK

If your working in a horticultural environment you could try Zerotol, (hydrogen dioxide) which works on contact, is organically approved, and degrades relatively quickly to water and oxygen. I wouldn't use it in a home or any place there are children as it is quite caustic in it's concentrated form. Test on a sample as it can be phytotoxic on some plants.
