Peter Cundall, the presenter of Gardening Australia, also presents a
radio show. Below is a link to a story on that radio show regarding home
made white oil.

Also try http://www.thewaterwisegarden.com/bicarb.htm
Water wise garden has a recipe to treat powdery mildew and blackspot, plus
one for white oil.

I actually had found the recipe by Mr Cundell, and some by one or two
others, but it is always good for other posters to mention useful sites.
Not everyone reading newsgroups has cheap access to the web, so although
most people can go to a given URL, not all can indulge their own search
engine investigations as thoroughly as is often needed.
