DKY OK POWDERED SUBSTITUTES FOR TlllO LIQUID lA^lK- 



SULPHUR. 



Substitutes for the liquid lime-sulphur in the dry or ])owdered form 

 are now offered on the market. They may have an advantage over the 

 liquid in economy of shipping and may be a little easier to handle. They 

 will dissolve in water and are then used exactly as is the liquid lime 

 sulphur, poison is added as desired. 



The value of these substitutes should depend upon the amount of sul- 

 phur they contain, and sufficient quantities must be used to make a spray- 

 ing mixture strong enough to be efficient. 



Their relative value compared with concentrated liquid lime-sulpliur 

 is given in the table below :

Knowing the amount of material required for 50 gallons and the cost 

 per pound, the expense as compared with the liquid lime-sulphur, either 

 the commercial concentrated, or the home-made may be determined.
