Use patterns and formulations: Application sites: Primary use Is to control alga growths in Impounded waters, lakes, ponds, reservoirs, and Irrigation and irrigation drainage conveyance systems. Other sites Include foliar applications for control of foliar pathogens on fruit, nut, vegetable, and field crops, ornamentals, and agricultural and home garden uses. Copper sulfate Is also registered for use as a weed seed treatment, for treatment of tree wounds, for control of fungi and fungal/bacterial slimes occurring In wood, and 111 water systems, including sewer pumps and force mains, pulp and paper mills, cooling towers and spray ponds. Types of formulations: Basic copper sulfate Is formulated as crystalline solids, 12.75 and 53-0 percent wettable powders, 30.0 percent liquid concentrate, and 2.0 and 52.0 percent dusts. Types and Methods of Application: In Impounded waters, lakes, ponds, reservoirs and irrigation systems, copper sulfate can be applied by spraying or dusting the water surface, large crystals can be placed In a burlap bag and towed behind a boat, or dumped In directly, or finer crystals can be metered In continuously. Application Rates: Prom 0.0013 to 10.0 ppra for aquatic uses and from 0.24 to 21.2 Ib a.l./A for terrestrial uses. Usual carriers: Water, or no carrier. ------- 3. Science Findir s : & nary science stat nent: Copper sulfate is exenpt fran the require ents of a tolerance when It Is applied to growir crops. There is also a specific ex nption fran the requir nent of a tolerance for copper in neat, milk, poultry, s, fish, shellfish, and irrigated crops when copper sulfate pentahydrate is used as an algicide or herbicide in ponds, reservoirs, or other bodies of water. se ex nptiona are ll founded. No edditional toxicology st ies are required. Copper sulfate is in Toxicity Category I as an eye and dermal irritant. Copper sulf te is toxic to fish and may present a hazard to aqtatic organi ns, especially when used as an algicide or rnolluscicide.
