    en.wikipedia.org/wiki/Copper(II)_sulfate

    Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]

  3. Copper(I) sulfate - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_sulfate

    Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu 2 SO 4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available. [1]

    Brochantite is a sulfate mineral, one of a number of cupric sulfates.Its chemical formula is Cu 4 SO 4 (OH) 6. [2] [3] [4] Formed in arid climates or in rapidly oxidizing copper sulfide deposits, it was named by Armand Lévy for his fellow Frenchman, geologist and mineralogist A. J. M. Brochant de Villiers.

    Copper(II) sulfate is used as a fungicide and is also used in conventional agriculture (LD 50 300 mg/kg). Conventional agriculture has the option to use the less toxic Mancozeb (LD 50 4,500 to 11,200 mg/kg) Lime sulfur (aka calcium polysulfide) and sulfur are considered to be allowed, synthetic materials [181] (LD 50: 820 mg/kg)

    en.wikipedia.org/wiki/Bordeaux_mixture

    Bordeaux mixture (also called Bordo Mix) is a mixture of copper(II) sulphate (CuSO 4) and quicklime (Ca O) used as a fungicide. It is used in vineyards, fruit-farms, vegetable-farms and gardens to prevent infestations of downy mildew, powdery mildew and other fungi. It is sprayed on plants as a preventive treatment; its mode of action is ...

    en.wikipedia.org/wiki/Chelates_in_animal_nutrition

    The bioavailability of Cu and Zn chelates in sheep have been compared to the inorganic sulfate forms, at "low" and "high" supplementation rates. Copper and Zn chelates at the lower rates caused significantly greater increases in blood plasma concentrations than the corresponding treatments with Zn sulfate (p<0.05) and Cu sulfate (p<0.01). In ...
