Use 2 lbs . of Copper Sulfate Crystals in 60,000 gals (8,000 cu ft) of effluent to yield 1 ppm of dissolved copper. Dosage levels may vary depending upon organic loa d. Other Organic Sludges: The solu tion of crystals must be thoroughly mixed with sludge . Dissolve 2 lbs of crystals in 1-2 gals of water and apply to each 60,000 gals of sludge . Maximum applfcatTon rate is 4 ppm Copper Sulfate Crystals (1 ppm metallic copper). Minimum retreatment interval is 14 days. TO CONTROL ALGAE IN RICE (Domestic and Wild) FIELDS : Application should be made when algae have formed on the soil surface in the flooded field. Applications are most effective at the first sign of algae after the field has been flooded and prior to the algae's leaving the soil surface and rising t o the water surface. Apply to the water surface as either crystals or dissolve in water and make a surface spray. For a 3-inch flood depth, apply Copper Sulfate Crystals at a rate of 2 .72 lbs per acre . Likewise, for a 6-inch flood depth, use 5.44 lbs per acre. Adjust the rate accord in g to average water depth , not to exceed the maximum application rate of 4 ppm Copper Sulfate Crystals (1 ppm metallic copper), which i s equivalent to 10.88 lbs Copper Sulfate Crystals I acre foot of water. TO CONTROL TADPOLE SHRIMP IN RICE (Domestic and Wild) FIELDS : Tadpole shrimp in rice fields may be effectively controlled by the prompt and proper use of Copper Sulfate Crystals. After the rice field has been flooded , Copper Sulfate Crystals should be uniformly applied at the first sign of infestation. For a 3-inch flood depth, apply 6.8 lbs per acre. For a flood depth of 6 inches, use 13.6 lbs per acre. Adjust the rate e~ccording to average water depth , not to exceed the maximum application rate of 10 ppm Copper Sulfate Crystals (2.5 ppm metallic copper), which is equivalent to 27 .2 lbs Copper Sulfate Crystals/ acre foot of water. SCHISTOSOME-INFECTED FRESH WATER SNAILS: For recreationalle~kes , reservoirs , and ponds, 5.44-13.6 lbs/acre-ft Copper Sulfate Crystals (i.e., 2-5 ppm Copper Sulfate Crystals), 1s usually sufficient for treatment of Schistosome-infected fresh water snails. Use surface area in acres multiplied by average depth in feet to det ermine water volume and application rate . Apply only along shoreline swimming areas and/or to infected snail beds on a calm sunny day when water temp is at least 60°F. Not allowing swimming for at least 12 hrs following treatment is recommended. A second application may be made if necessary, 1 0 to 14 days later. DO NOT make rnore than two applications per calendar year. Apply by broadcast application using boat, aircraft, or hand equipped w ith power or hand seeder or underwater dispenser. Do not exceed 1 ppm copper (4 ppm Copper Sulfate Crystals) in potable water systems. This labeling must be in the possession of the user at the time of pesticide application. Maximum application rat e is 6 ppm Copper Sulfate Crystals (1.5 ppm metallic copper). Note; 6 ppm Copper Sulfate Crystals= 16.32 lbs of product /acre ft .. NOTE : In the State of New York-For use in recreational lakes, reservoirs and ponds ONLY in areas where infected snail beds have been identified . Apply medium grade crystals by hand broadcast method of application only . This product is a restricted use pesticide in New York State. Pesticide applicator certification or a special use permit is required for sale , possession, or use. Each individual treatment must be approved by the Department of Environmental Conservation . Therefore, you must contact the Pesticide Control Specialist at the appropriate regional office of the Department 30 days in advance of the proposed treatment. 7 6.3.A. - Page 130
