But it must be distinctly understood that at this strength (either 1 to 8, 

 or 1 to 10) it must not be used after the buds have opened. 



If the grower for any reason wishes to depend on the ready-made 

 lime-sulphur to control Oyster-shell Scale, and can not give the above 

 mentioned winter treatment, then we advise that he use it at rate of 1% 

 gallons to 50 gallons water, and apply it in late April or early May. 



Home-made Lime-sulphur Wash. This was for some time the chief 

 remedy for scale-insects of the orchard, and is still the chief reliance of 

 many thoroughly up-to-date growers, though it is being displaced to a 

 great extent by the more convenient commercial washes. It is prepared 

 as follows: 



Stone Lime (unslaked) 15 pounds. 



Sulphur ( Flowers) ' 15 pounds. 



Water (to make) 50 gallons. 



Heat from four to six gallons water to boiling in large iron or brass 

 kettle. Mix the sulphur with enough hot water to make a thin paste 

 and pour it into the kettle with the hot water. ISTow add the lime, part 

 at a time, and as it slakes dash in a little cold water as needed, to keep 

 it from boiling over or to keep it from becoming dry. Keep the fire 

 going and stir frequently. As the slaking ceases, keep it boiling from 

 the fire for half an hour longer, then dilute with water (cold is all 

 right) to make 50 gallons; strain through a fine wire screen or cloth to 

 remove sediment, and spray. 



This wash at the strength here given is only for use in winter before 

 the buds open. The later the treatment is made the better, so the buds 

 have not yet opened.
