this solution at home according to the following formula: 



15 lbs. sulphur 

 15 lbs. quicklime 

 50 gals, water 



The lime is slacked, with hot water, and while it is slacking 

 the sulphur is poured in rapidly. After mixing, the amount 

 of water is increased to 15 gallons, and then feoiled briskly 

 for 45 minutes. The most common practice is to prepare this 

 solution in an open kettle. However, some growers have elab- 

 orate and "convenient outfits for making lime -sulphur. 



Commercial concentrate lime -sulphur solution is used 

 by some growers for winter spraying. The commercial con- 

 centrate is diluted with water to the required strength. 



A convenient table for making dilutions of the com- 

 mercial concentrated lime-sulphur is found in Bulletin No. 

 320, of the New York Agri. Exp. Station, and is reported be- 

 low in part.
