W. M. Scott's Formula. 



Flowers of sulfur or sulfur Hour, 8 poiuids. 



Fresh stone lime, (S pf)unds. 



Water, 50 gallons. 



In making this mixture the best stone lime procurable should be 

 placed in a barrel and slaked, using precautions not to drown the 

 lime in slaking it. W. M. Scotc recommends that enough water be 

 applied to nearly cover the lime when slaking. As soon as the lime 

 has commenced to slake and some heat has generated, apply the 

 sulfur through a fine sieve to break up the lumps. The mixture 

 should be stirred and more water added gradually, bringing it to a 

 thin paste. As soon as the lime is well slaked, more water should be 

 added to ct)ol the mixture. 



Since there is much difference in lime as regards the development 

 of heat, it is difficult to specify any particular time to add the water 

 for the purpose of cooling, but it should be done before the sulfur 

 goes into solution and fomus sulfides, which are injurious to peach 

 foliage. Under ordinary conditions, the mixture sliould not be allowed 

 to remain hot over ten or fifteen minutes after slaking. With the 

 intense heat developed from slaking and constant stirring a uniform 

 mixture of fairly finely divided sulfur and lime is obtained with only 

 a small trace of sulfides in solution. It should be strained before 

 use. 



Mr. Scott has used this successfully for peach brown rot and scab. 

 In this formula he also mixed two pounds of arsenate of lead, which 

 proved effective in controlling plum-weevil. Mr. Scott believes that 

 the arsenate of lead is less likely to burn tender foliage when in com- 

 bination with lime and sulfur than when used alone. 



Concentrated Lime and Sulfur 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° Baume, 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,
