Which is better fungicide: copper or sulfur?

[snakecharma]

I would think that the copper base would be more suitable for root issues that the sulphur, but afaik both are fine.

I use a milk base spray for fungus prevention on leaves, it's what we use on our roses for the dreaded black spot. You guys know that one?

Can't you just get copper sulfate? In france copper sulfate is widely used for treatement in the vineyards and or many plants. It works much better as a preventative measure rather than curative, and i suspect it's the same for only copper or only sulfate products

copper sulfate is known as Bordeux mixture because it is used on grapes and was discovered to be a fungicide by the growers in the Borduex region of France.....

I dont know but I am just a little cautious of it in s/h since it is also used as a algae treatment so I have the feeling it has herbicidal properties in a wetter situation than foliar applications?

Try Phyton 27. It can be used as a foliar spray, a root drench, etc. Physan 20 has no fungicidal properties. It is a bacteriacide/disinfectant.

Not true, Terri. Physan 20 is a bactericide, fungicide, algaecide and virucide. Specifically, it is a topical treatment, not a systemic one.

When I first started gardening, all of the old-timers recommended spraying milk on the leaves of plants to prevent fungus. I use this for my tropical plants when they are outside for the summer (I stop once I bring them indoors) and have never had a problem, no matter what the weather.
