COMMERCIAL LIME AND SULPHUR CONCENTRATED 



SOLUTIONS. 



There are a number of these solutions on the market which are 

 apparently similar in composition. Their specific gravity varies 

 from 30° to 34° Beaume, and in using them it is necessary to dilute 

 according to the strength of the solution and the nature of the foliage 

 to which they are to be applied. The directions furnished by manu- 

 facturers for the dilution of their own product for different purposes 

 can usually be relied upon. 



LIME AND SULPHUR SOLUTION— Geneva Formula. * 



Lime (pure,) 36 lbs. 



Sulphur (high-grade, finely divided,) 80 lbs. 



Water, 50 gals. 



This is prepared by first moistening the sulphur and making it in- 

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

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

 the sulphur 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 concen- 

 trated solution is recommended by the Geneva Experiment Station, 

 where extensive investigations have been made relative to the lime 

 and sulphur solutions. 



When the solution is made to 50 gals, it should have a density of 

 from 24° to 25° Beaume. The Geneva Experiment Station recom- 

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

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

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

 only slight amounts of sediment are present, whereas if the lime con- 

 tains impurities, the amount of sediment is an indicator of the purity 

 of the lime. The solution can be stored in filled, stoppered barrels 

 for some time if the temperature does not fall below 5° F.
