/'/ I,H ration. The preparation differs from that of the home made 

 boiled lime-sulphur, in that only the heat of the lime, which is generated 

 during the slacking process, is utilized. It is made in a barrel or tank, 

 which may be covered tightly to retain the heat for about 15 or 20 

 minutes, when a slight amount of the sulphur and lime will have com- 

 bined. It is diluted with cold water, after being strained. 



In some of the states to the east the self -boiled lime-sulphur alone, 

 or in combination with arsenate of lead, has been used very successfully 

 for apple scab and mildew, but has not been generally recommended 

 under California conditions. 



Atomic or Milled Sulphur. 



Very finely divided sulphur may now be purchased for spraying pur- 

 poses. The forms known as ' ' Atomic ' ' and * ' Milled ' ' sulphurs are com- 

 monly used for mites with great success, and are excellent mildew fungi- 

 cides. The directions for mixing come with the packages.
