Many thanks for the links, Dice.
Unfortunately It seems that Oxidate is not available to us in the Uk. We are very limited with what we can get hold of. The Baking Soda link is very helpful. I shall have to find out what % hypochlorite is in our household bleach.
Thanks again
Gill

Baking Soda as a fungicide (research summary):

The active ingredient in Dithane is mancozeb (not a
Daconil product). This site suggests that some
uses of mancozeb can be replaced by Oxidate,
including control of botrytis:

Search the disease forum here for threads on late blight.
There are some good summaries, particularly from Cornell
University.

I have now discovered that 'baby bottle steriliser' is about 5% Sodium Hypoclorite. Should I then be using this at 6% dilution as an antifungal spray! This is all very confusing!
Thanks
Gill

[Clorox and equivalents]
I seem to recall that the sweet spot for b54red was about
7% Clorox. I do not know how exact his measurements are
when mixing it up. I looked at a jug of Clorox today, it said
"6% sodium hypochlorite". If your sodium hypochlorite product
is 5%, then you would mix it up at (6/5 * 7) %, or 8.4 %
sterilizer in water to duplicate the strength of his Clorox solution.

So, you would mix about .38 liters of baby bottle sterilizer to
a British gallon of water. (Say, a third of a liter or so
of sterilizer in a UK gallon jug, fill up with water, spray.)

Thanks for doing the arithmetic for me, Dice.
I have had some rotting of green tomatoes starting at the calyx. Botrytis I assume.
I made some of the hypochlorite solution today and gave everything a good spray. Fingers crossed it works. From things I am reading seems it to have been a bad season for fungal infection everywhere.

That sounds more like an 'organic' fertilizer than a disease treatment...although I'd be a little concerned about mixing the the baking soda and the Epsom salts...because, under some conditions, I can see you ending up with table salt (sodium chloride) as a possible 'leftover'.

As a fert, the milk would be an added nitrogen source. The compost would be the 'base nutrients', the milk: a nitrogen booster, the Epsom salts: a shot of trace minerals, along with the baking soda (and possible acid neutralization...with a slight chance of salt build up). It actually sounds like it would be a great asparagus fertilizer...
