Bordeaux mixture

<p>Bordeaux mixture (also called <i>Bordo Mix</i>) is a mixture of <a href="/facts/Copper(II)_sulphate/Ya6fPoQe">copper(II) sulphate</a> (CuSO4) and <a href="/facts/Quicklime/Wh9C8l7j">quicklime</a> (<a href="/facts/Calcium/hf252CC0">Ca</a><a href="/facts/Oxide/DXtoVe1C">O</a>) used as a <a href="/facts/Fungicide/c1twQBYo">fungicide</a>. It is used in vineyards, fruit-farms, vegetable-farms and gardens to prevent infestations of <a href="/facts/Downy_mildew/IDpEbpdQ">downy mildew</a>, <a href="/facts/Powdery_mildew/qAl00hYE">powdery mildew</a> and other fungi. It is sprayed on plants as a preventive treatment; its mode of action is ineffective after a fungus has become established. It was invented in the <a href="/facts/Bordeaux_wine/m3rJsyVA">Bordeaux region</a> of France in the late 19th century. If it is applied in large quantities annually for many years, the copper in the mixture eventually becomes a <a href="/facts/Pollutant/4f9kmFzq">pollutant</a>. As such its use is controlled, but not forbidden in most of the <a href="/facts/European_Union/6GYcR8qM">European Union</a>. Despite this, some advocates of organic gardening consider it an '<a href="/facts/Organic_agriculture/Rce4nxdU">organic</a>' pesticide.
