Copper fungicides are one of the top weapons in the fight against fungal diseases in plants. Almost all copper fungicides have a fixed copper as the active ingredient, with copper hydroxide, not copper sulfate, the most common. However, many use copper sulfate as well. Copper sulfate is a chemical that can kill algae, bacteria, and fungi.
