Ok found it,

Copper Oxychloride

So its just another dose of COPPER

 

I have heard it said, from more than one source, that there was nothing wrong with Cheshunt compound - except that it was generic - ie public property. I understand that all garden chemicals have been banned until they have passed an expensive testing routine ordered by the European authorities.

But who is going to test a public property product that, once it has passed, can then be manufactured by anyone. I think the new alternative is just a copper variant that can be patented by Bayer.

I have used both the old and the new. The old remains in solution, but the new one doesn't - it settles and then is difficult to dissolve again. So I would still use the old (if I was allowed to - of course :D).

 

Make your own John, the chemistry is simple. You might like to do some Googling to find independent verification that this recipe is kosher:

When I was a kid err 50's we had chemistry sets :-)
when we had used up everything we went to the chemist and bought for pennies COPPER SULPHATE, FLOWERS OF SULPHUR Etc

So although garden outlets do not sell it, Can it not be bought from a chemist ?

Duh just checked off course you can,
Copper Sulphate 1k £7
Flowers of Sulphur 1k £7

In that case I predict a repeated, accidental, spillage every time you fill a new seed tray!

 

Any idea of what should spill into what, accidentally to assist any strugling plant life ?

No, none whatsoever, but hypothetically speaking (in case my lawyer is reading this and planning to give me a good kicking tomorrow ...) Chesthunt Compound was traditionally used on seedlings as a fungicide to reduce the risk of damping off disease.

Damping off disease causes all your little seedlings to keel over and then its "Goodnight Vienna" :( but having said that I think "Damping off disease" is very rare, if you use good husbandry (clean seed trays, sterile compost) and don't stress the seedlings

What I don't know is why Chesthunt Compound was so widely used for seedlings rather than any other fungicide? Perhaps normal fungicides were too strong and just killed seedlings?

I water (hypothetically speaking still, of course ...) all seed trays of difficult / long-time-germination seeds with Chesthunt Compound (both before sowing and if they need watering thereafter); unless the seed is scrupulously clean there is a chance that it will start a mould reaction anyway. Alternatives to that are a Hydrogen peroxide "bath" for the seeds before sowing (you'll need to look up the concentration, its obviously important that its not too strong!). I don't know whether H2O2 is also useful when watering seed trays (with regard to Damping Off), but it certain does have some beneficial action as it releases Oxygen; its probably about the only "tonic" you can usefully give a plant that is showing stress as a result of over watering. H2O2 often used as a "bath" for bulbs before starting them off if they are prone to rot - such as Colocasia ... right, I'm getting right off topic now, so I'll shut up!
