It seems that Dithane has risen from the grave.
Changing the name by adding 3 numbers shouldn't fool anyone, and if it really is a different molecule, well, that just means it's going to have its own ban in a few years when its own problems emerge from the woodwork.
Does it still make your tomatoes taste of rotting cabbage?
I've tried to Google a simple list of approved "plant protection" substances and their initial approval date. It just leads you into a maze...
I'm relying on my memory - it tells me that nothing synthetic has lasted more than 10 years, if so why the endless optimism about new ones? eg. Benlate really was non-toxic straight from the packet - until its dire effects on pregnancy appeared.
Cheers.
PS. Copper has been used since the 1840s - it's only real problem is that its profits are too small. There are thousands of imaginary problems - despite the fact that it is a normal constituent in soils and it's essential to mammals in quantities comparable to your exposure from tomatoes, never mind potatoes. It doesn't really work in a bad blight year - but Dithane didn't work in a bad year anyway.
