Home Made Lime and Sulfur Solutions. 



Experience has shown that the best concentrations of hme and 

 sulfur are obtained by using about twice as much sulfur as lime, 

 since this preparation gives the least sediment. Nothing but the 

 best fresh stone lime should be used in making lime and sulfur. Air 

 slaked lime should not be used under any circumstances, and in 

 many cases it is advisable to use hot instead of cold water in slaking 

 the lime. 



LIME AND SULFUR SOLUTION— Geneva Formula.* 



Lime (pure), 36 pounds. 



Sulfur (high grade, finely divided), 80 pounds. 



Water, 50 gallons. 



This is prepared by first moistening the sulfur and making it into 

 paste. Then slake the lime in about 10 gallons of hot water, adding 

 the lime gradually to prevent violent boiling and spilling over. Add 

 the sulfur paste gradually during the slaking and stir constantly to 

 prevent the formation of lumps. When the slaking is complete add 

 the full amount of water, and boil for one hour. The boiling may be 

 accomplished by the use of steam or by wood fires and kettles. In 

 either case maintain the original volume of water. This concentrated 

 solution is recommended by the Geneva Experiment Station, where 

 extensive investigations have been made relative to the lime and 

 sulfur solutions. 



When the .solution is made to 50 gallons it should have a density 

 of from 24° to 25° Baume.f The Geneva Experiment Station recom- 

 mends that where the lime is 95^r pure, 38 pounds should be used, 

 and where only 90^ pure, 40 pounds. According to their tests, when 

 one part of pure lime and two parts of sulfur are boiled one hour, 

 only slight amounts of sediment are present. Sediment indicates im- 

 purity of the lime used. The solution can be .stored in filled, stop- 

 pered barrels for some time if the temperature docs not fall be- 

 low 5° F.
