What strength do I make copper hydroxide spray for fungus control on stone fruit?

Copper hydroxide can be applied to peaches and nectarines for leaf curl control at the first sign of budswell and repeated one week later. (A spray at leaf fall is also recommended.) For control of freckle and shothole in apricots, apply this product at early budswell and also apply one spray post harvest. Mix the product at the rate of two grams per one litre of water.
