When a reduced water flow is first noticed, and root growth is thought to be the cause , treat with Copper Su lfate Crystals . It is important not to wait until a stoppage occurs because some water flow is necessary to move the Copper Sulfate Crystals to the area of root growth . Usually, within 3 to 4 weeks, after roots have accumulated sufficient copper su lfate, the roots will die and begin to decay and water flow should increase. As the roots re·grow, follow-up treatments with Copper Sulfate Crystals will be required . Applications may be made each year in the spring after plant growth begins, or during late summer or early fall , or any time a reduced water f low, thought to be caused by root growth, occurs. Apply 2 pounds Copper Sulfate Crystals to household sewers. Add Copper Sulfate Crystals to sewer line by pouring 1/2 pound increments into the toilet bowl nearest the sewer line and flush , repeat this process unti l recommended dose has been added , or remove cleanout plug and pour entire recommended quantity directly into the sewer line. Replace the plug and flush the toilet seve ral times , Repeat in 6 or 12 month intervals, if necessary. ROOT CONTROL I N SEPTIC TANKS, LEACH LINES AND LEA CH LINE PIPES: The majority of the Copper Su lfate Crystals will settle in the septic tank itself and little will pass into the l each lines. To treat leach line pipes, add 2 pounds of Copper Su lfate Crystals to the distribution box located between the septic tank and the leach lines. To achieve effective root control in the leach lines it is necessary to transfer Copper Sulfate Crystals from the septic tank to the leach lines. A cleanout plug opening may need to be install ed if the distribution box does not have an opening lead i ng to the leach lines. Repeat in 6 or 12 month intervals, if necessary. *NOTE: Do not apply Copper Su lfate Crystals through sink or tub drai ns as it will corrode the metal drains . *NOTE: Copper Sulfate Crystals added to an active 300 gallon septic tank at 2 pounds per treatment will temporarily reduce bacterial action, but it will return to normal approximately 15 days after treatment. Trees and shrubbery growing near a treated line normally are not affected due to only a small portion of their roots being in contact with the Copper Sulfate Crystals. Copper Sulfate Crysta ls kills on ly those roots inside the leach line. *NOTE: Do not use as a sewer additive where prohibited by State law. State law prohibits the use of this product in sewage systems in the State of Connecticut. Not for sale or use in the California counties of Alameda, Contra Costa , Marin, Napa , San Francisco, San Mateo, Santa Clara , Solano, and Sonoma for root control in sewers. Not for sale or use in septic systems in the States of Florida and Massachusetts and State of Washington. *NOTE: For all sewer line treatment applications do not use more than 2 lbs Copper Sulfate Crystals (0.5 lbs. meta ll ic copper) per applicati on. Minimum retreatment interval is 6 months. Make no more than two applications per calendar year. Per EPA guidelines, do not exceed 8 lbs Copper Sulfate Crystals (2 lbs metallic copper) per year. TO CONTROL ALGAE AN D THE POTOMOGETON POND WEEDS, LEAFY AN D SAGO, IN IRRIGATION SYSTEMS: Once the amount of Copper Sulfate Crystals required for treating ditches or streams has been calculated, use a continuous application method, selecting proper equipment to supply the granu lar crystals . Minimum retreatment interval is 2 weeks. FOR ALGAE CONTROL -Begin continuous addition application of granular Copper Sulfate Crystals when water is f irst turned into the system and continue throughout the irrigation season , applying 0.1 to 0.2 lbs Copper Sulfate Crystals per hour per cubic ft per second for 12 hours of each 24 hours. This rate provides 0.112 to 0.224 ppm metallic copper in the treated water. Maximum application rate is 4 ppm Copper Sulfate Crystals (1 ppm metallic copper). Note: 4 ppm Copper Su lfate Crystals= 10.88 lbs of product/acre ft. =1 .0 ppm metallic copper in the treated water. FOR LEAFY AND SAGO POND W EED CONTROL -Use the same contin uous feeder, applying 0.5 to 0.9 lbs Copper Sulfate Crystals per hour per CLibic foot per second for 12 hours of each 24 hours. This provides 0.5 to1.0 ppm metallic copper in the treated water. Maximum application rate is 4 ppm Copper Sulfate Crysta ls (1 ppm metallic copper). NOTE: For best control of leafy and sago pond weed , it is essential to begin Copper Sulfate Crystals additions when water is first turned into the system or ditch to be treated and to continue th rou ghout the irrigation season. Copper Su lfate Crystals becomes less effective as the alkalinity increases. Its effectiveness is significantly reduced when the bicarbonate alkalinity exceeds 150 ppm. Should Copper Sulfate Crystals fail to control pond weeds satisfactorily , it may be necessary to treat the dftch with either a suitable approved herbicide or use a mechanical means 5 6.3.A. - Page 128
