Rosemary from Port Saint Lucie, Fl writes

Is Monterey Liqui-Cop a copper sulfate? I have lichen and green fungus growing on some of my trees. Will it kill these?


Monterey Liqui-Cop is not labeled for lichen or algae.   You can use Crystal Blue Copper Sulfate to kill lichen/algae on trees. Please see the product label for complete application instructions.
