(a) Copper is exempted from the requirement of a tolerance in meat, milk, poultry, eggs, fish, shellfish, and irrigated crops when it results from the use of: (1) Copper sulfate as an algicide or herbicide in irrigation conveyance systems and lakes, ponds, reservoirs, or bodies of water in which fish or shellfish are cultivated. (2) Basic copper carbonate (malachite) as an algicide or herbicide in impounded and stagnant bodies of water (3) Copper triethanolamine and copper monoethanolamine as an algicide or herbicide in fish hatcheries, lakes, ponds, and reservoirs (4) Cuprous oxide bearing antifouling coatings for control of algae or other coatings for control of algae or other organisms on submerged concrete or other (irrigation) structures. (b) The following copper compounds are exempt from the requirement of a tolerance when applied (primarily) as a fungicide to growing crops using good agricultural practices: Bordeaux mixture, basic copper carbonate (malachite) (CAS Reg. No. 1184-64-1), copper ethylenediamine complex, copper hydroxide (CAS Reg. No. 20427-59-2), copper lime mixtures, copper linoleate (CAS Reg. No. 7721-15-5), copper octanoate (CAS Reg. No. 20543-04-8), copper oleate (CAS Reg. No. 10402-16-1), copper oxychloride (CAS Reg. No. 1332-40-7), copper sulfate basic (CAS Reg. No. 1344-73-6), cupric oxide (CAS Reg. No. 1317-38-0), and cuprous oxide (CAS Reg. No. 1317-19-1). (c) Copper sulfate pentahydrate (CAS Reg. No. 7758-99-8) is exempt from the requirement of a tolerance when applied as a fungicide to growing crops or to raw agricultural commodities after harvest. (d) Copper (II) hydroxide (CAS Reg. No. 20427-59-2) is exempt from the requirement of a tolerance when applied to growing crops or to raw agricultural commodities as an inert ingredient (for pH control) in pesticide products.
