How much to use and how often?

You'll want to dilute it down A LOT. A spray bottle that is ~800ml (regular sized bottle) only needs 8ml of zerotol to get the right concentration for cleaning plant trays. (1:100) this jug will last a long time

will this work on blackspot on roses?

Yes it should, be sure to spray early in the morning but if you don’t think it’s working, try The Amazing Dr. Zyhmes
