Copper Sulfate
Pentahydrate Fine Crystals (Pesticide Label)
Copper Sulfate Pentahydrate is an odorless blue crystal that readily dissolves in water. It is also soluble in methanol, glycerol and slightly soluble in ethanol. Copper Sulfate, sometimes referred to as Blue Vitriol or Bluestone, is a readily available and economic source of copper.
uses
Copper salts, including copper Sulfate Pentahydrate Fine Crystals, are regularly used to prevent the development of algae in potable water reservoirs. The salts are employed to control green slime and similar algal scums in farm ponds, rice fields, irrigation and drainage canals, rivers, lakes and swimming pools. Another well-known use for copper compounds is as a molluscicide for the control of slugs and snails.
Copper Sulfate Pentahydrate Fine Crystals, minus 30 mesh, control tadpole shrimp populations in flooded rice fields, as well as contain the spread of various fungal diseases. The fine crystals are also applied in sewer treatment to destroy roots.
Copper Sulfate Pentahydrate Fine Crystals serve as the main ingredient for manufacturing Bordeaux and Burgundy mixtures that are used as algaecides, both on the farm and to ensure safe water supplies. Bordeaux mixtures are also employed to adjust and maintain copper deficient soils to optimum levels.
OB’s Copper Sulfate Pentahydrate Crystals are registered with the Environmental Protection Agency for pesticide applications (EPA Reg. No.46923-4).
