Can I use copper sulphate to remove algae growing on my concrete paths?
Currently have Copper sulphate powder -CU as Sulphate 25 %S 12 %. What is your dilution rate to kill or prevent ?

Yates Bluestone Copper Sulphate in the same concentration can be used to control algae on paths. Dissolve 5 gmin a 9 litre non- metallic watering container and apply over the affected area.
