Fungicides

If anyone has any experience using either of these products, I'd appreciate any thoughts you have on them. The first is called 'Sunniland Coppercide Homeowner Liquid Fungicide'. The ingredients are listed as Copper Salts or Fatty and Rosin Acids....48%; Equivlent to Copper as metallic...4%; Inert...52%
The other product was sold to me as being exactly like Physan 20. It is called SA-20 Disinfectant. Its ingrediants are as follows: Ankyl (C14 60% C16 30% C12 5% C18 5%) dimethyl benzyl ammonium chloride...10%; Ankyl (C12 68% C14 32%) dimethyl ethybenzyl ammonium chloride...10%; Inert...80%.
I'd want to be using either of these as possible fungicides on orchids, but although there are ornamentals listed on each, orchids are not mentioned. Don't need them yet, but just want to be prepared with all the very hot, humid weather we've been experiencing here. Thanks.

Be wary of copper-based fungicides, as some orchids can be damaged by them.

The SA-20 looks a lot like Physan. used at about a teaspoon per gallon, it ought to be a good contact cleanser. It will not help with systemic infections; surface only.

Thank you, Ray. I hoped you'd be by.
Cheers,
