136 SPRAY MACHINERY AND SPRAY MATERIALS 



Place the lime in a barrel and pour on enough water to 

 start the slaking of the lime. Then add the sulphur after 

 sieving it to remove any lumps and stir the mixture thor- 

 oughly, finally adding sufiicient water to make a paste. 

 Constant stirring is necessary to prevent caking. After the 

 boiling produced by the slaking of the lime is o\'er, the mix- 

 ture should be diluted to the 50 gallons and it is then ready 

 to use. 



This fungicide is very satisfactory for use on the peach, the 

 American and Japanese plums, and upon some varieties of 

 cherries. 



COMMERCIAL LIME-SULPHUR SOLUTION. 



The commercial lime-sulphur solution is a good fungicide 

 when diluted to the proper strength. In fact it is uni\'ersally 

 used on many of our fruits and particularly the apple. This 

 fungicide, howe\'er, is not \'ery satisfactory in controlling 

 the rots, but it is good for the apple scab, the flyspeck fungus 

 and some other diseases. 



The dilution of this fungicide is based upon the density 

 of the solution, the same as it is for the insecticide, except 

 that the spray must be much weaker as a fungicide than as 

 an insecticide. The table gi^'es the dilution based upon the 

 degree Baume of the commercial product.
