The exact chemical reaction leading to the synthesis of lime sulfur is generally written as: Ca(OH) 2 + x / 8 S 8 → CaS x + by-products (S 2 O 2− 3, SO 2− 3, SO 2− 4) as reported in a document of the US Department of Agriculture (USDA).
One kg of CuSO 4 actually requires only 0.225 kg of chemically pure hydrated lime to precipitate all the copper. Good proprietary brands of hydrated lime are now freely available, but, as even these deteriorate on storage (by absorbing carbon dioxide from the air), a ratio of less than 2:1 is seldom used, which corresponds to a 1:0.5:100 mixture.
Dicofol, a compound structurally related to the insecticide DDT, is a miticide that is effective against the red spider mite Tetranychus urticae. Lime sulfur is effective against sarcoptic mange. It is made by mixing hydrated lime, sulfur, and water, and boiling for about 1 hour.
Milk of sulfur (lac sulphuris) – formed by adding an acid to thion hudor (lime sulfur). Natron/soda ash/soda – sodium carbonate. Na 2 CO 3; Nitrum flammans – ammonium nitrate. Sugar of lead – lead(II) acetate, formed by dissolving lead oxide in vinegar. Thion hudor – lime sulfur, formed by boiling flowers of sulfur with slaked lime.
[2] [8] [12] [7] Lime sulfur is most commonly used and safe pesticide to control Notoedric mange on cats. Treated cats should not be allowed to groom before their coat is fully dried after treatment, because lime sulfur can cause toxicity if it is orally ingested. [ 12 ]
