  2. Copper pesticide - Wikipedia

    en.wikipedia.org/wiki/Copper_pesticide

    Copper pesticide is applied as a contact protective foliar spray, so it remains deposited on leaf surfaces. A small concentration of copper ions may be taken up by plants as essential nutrients. Copper foliar sprays are also applied to correct plant copper deficiency. [8] Excess absorbed copper ions can kill sensitive cells in copper sensitive ...

    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 ...

    Copper naphthenate is classified by EPA as a general use (i.e., a non-restricted use) pesticide by virtue of its relatively benign toxicity profile. [5] Copper naphthenate is the only non-restricted use wood preservative in widespread use for "heavy duty" commodities such as utility poles, railroad crossties and timbers, pilings and fence posts.

  6. Burgundy mixture - Wikipedia

    en.wikipedia.org/wiki/Burgundy_mixture

    Dissolved copper sulfate ratios generally range from 1:1 to 1:18. Sodium carbonate is generally added in higher quantities and at a dissolved ratio of 1:1.5. Over time, the sodium carbonate will crystallize out of solution, and the closer the copper sulfate to carbonate mixture is to 1:1 ratios, the faster this process occurs. This property is ...

  9. Copper (I) chloride - Wikipedia

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

    The main use of copper(I) chloride is as a precursor to the fungicide copper oxychloride. For this purpose aqueous copper(I) chloride is generated by comproportionation and then air-oxidized: [12] Cu + CuCl 2 → 2 CuCl 4 CuCl + O 2 + 2 H 2 O → Cu 3 Cl 2 (OH) 4 + CuCl 2. Copper(I) chloride catalyzes a variety of organic reactions, as
