In agriculture and horticulture, lime sulfur is sold as a spray to control fungi, bacteria, and insects. On deciduous trees it can be sprayed during the winter on the surface of the bark in high concentrations, but as lime sulfur can burn foliage, it must be heavily diluted before spraying onto herbaceous crops, especially during warm weather.
Bordeaux mixture can be prepared using differing proportions of the components. In preparing it, the CuSO 4 and the lime are dissolved separately in water and then mixed. Calcium oxide (burnt lime) and calcium hydroxide (slaked lime) give the same end result, since an excess of water is used in the preparation.
Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.
The toxicity of these fungicides means they are not legally available to noncommercial growers in some countries. Spraying should be done in the winter well before budding. If trees are not sprayed early enough, treatment is ineffective. Copper-based mixtures (such as Bordeaux mixture) and lime sulphur are two fungicides commonly used. [2] [10]
Lime sulfur is effective against sarcoptic mange. It is made by mixing hydrated lime, sulfur, and water, and boiling for about 1 hour. Hydrated lime can bond with about 1.7 times its weight of sulfur (quicklime can bond with as much as 2.2 times its weight of sulfur). The strongest concentrate is diluted 1:32 before saturating the skin ...
