I have previously used this successfully to prevent damping off on tomato
seedlings.

I was looking to buy some more - but I cannot see it is available now.

My seedlings have just come through: fortunately I have enough Cheshunt
Compound left for a few waterings - but I am looking for a good alternative.

Any recommendations please?

It is/was a copper-based fungicide. Cheshunt is a mixture of copper
sulphate and ammonium carbonate (smelling salts). Bordeaux mixture is
similar, but uses lime in place of the ammonium carbonate. Bordeaux
mixture is still available, apparently http://tinyurl.com/npcr9ou .
Another one is copper oxychloride. I believe Bayer do it, amongst
others. http://tinyurl.com/nr72yus and sold as a replacement for
Dithane, it says in the details.

Recipes for Bordeaux mixture and Burgundy mixture are available on the
net if you're prepared to make your own (they get their names from the
fact that they were widely used in French wine-making areas for
treating grapes). http://www.abc.net.au/gardening/stories/s1631445.htm

I used to have a recipe for Cheshunt, although never made it myself. I
can't now actually find a recipe on the net ATM.


Cheers - I've just watered the tomato seedlings - I have just enough for one
more watering.

I will have to try one of the ones you have mentioned.

(When I was about 15 I used to buy Copper Sulphate by weight from my local
chemists. They would not sell it to me without a letter from my parents. My
mother duly obliged and authorised them to supply it (with other chemicals)
including Potassium Nitrate, sticks of Charcoal and Sulphur. !)

Found this on the net twice ....

Cheshunt Compound.
Weigh 60g of Copper Sulphate & 330g of Ammonium Carbonate.
These two are well powdered and well mixed.
The dry mixture is stood in an airtight glass container for 24 hours before
use, but can be stored bone dry for longer.
About 25g of this mixture is dissolved in hot water and the solution is made
up to 8 litres with cold water and used for soil drenching.

The last time I looked for this I found Traditional Copper Fungicide
which seemed to the same job successfully. A varity made by Murphe is
available from Amazon

http://www.amazon.co.uk/Murphy-Tradi...m/B0036EESSM/2

That is only one result from a google search
