Title: What has happened to Murphy Copper Fungicide?
Post by: BAK on April 11, 2010, 07:55:04
I use it for blight on outdoor toms.

Everybody that I have tried (garden centres and internet) is out of stock. No mention of it on Scotts website.

Has it been banned, withdrawn etc?

Anybody heard anything?

Thanks

I heard it was being discontinued because they were having difficulty locating sufficient quantities of the active ingredient (copper oxychloride) at an affordable price. However this is based purely on hearsay I have not heard anything about it from an official source.
It's still approved for use until 31/12/2013 which suggests it's disappearance is nothing to do with the CRD therefore has to be down to the manufacturers.

Bayer Fruit & Vegetable Disease Control is very similar to Murphys Copper Fungicide, you may be able to get this.

Or Vitax Bordeaux Mixture?

Bordeaux mixture sold as a powder isn't the same as the colloid you get when you mix copper sulphate and limewater (binary) and then spray immediately before it clumps.

It's hard to tell without a very high quality microscope but the resulting solution looks different - I suspect that the particles in the powder are bigger.

I don't think it is as effective as the binary - but there are too many variables to tell.

Making the binary solution is much cheaper if you can get CuSO4 for £10 a Kg - but to do this you generally need to buy a Kg (eg. Mole Farms).

Cheers.
