Will copper sulphate kill moss and not harm couch?

I have peat moss growing in couch grass. Will copper sulphate kill the moss and not harm the couch?

Hi Ivor,

To remove the moss in your couch grass you can use a product called sulphate of iron. It will kill off the moss without harming your lawn. The sulphate of iron is applied to a moist lawn, left for 2 days and then watered thoroughly after 2 days. In that 2 day period the sulphate of iron will kill the moss that is growing in the lawn area.
