DILUTE LIME-SULPHUR SOLUTION. 



For spraying on the foliage of apples, pears, European plums and 

 cherries but not on peaches or Japanese plums, grapes or potatoes. 



This solution can be prepared for use in several ways. 



First, The "Commercial" concentrated lime-sulphur solution can be 

 diluted to the proper strength. 



Second, The ''home made" concentrated lime-sulphur can be diluted to 

 the proper strength. 



Third, The solution can be made at any time and in any quantity as 

 follows: Boil in a few gallons of water for one hour, twice as many 

 pounds of sulphur as of lime, strain and dilute with water so there 

 will be 8 pounds of sulphur to every 100 gallons. 



Example: To make 100 gallons of spray solution, boil 8 pounds 

 of sulphur and 4 pounds of lime as directed. 



SELF-BOILED LIME SULPHUR MIXTURE. 



This is a mixture of lime, sulphur and water and not like any of the 

 other lime-sulphur sprays. It does not (when properly made) injure 

 tender foliage and is very valuable for spraying peaches and Japanese 

 plums. The formula is : 



Lump lime ' 8 pounds. 



Sulphur 8 pounds. 



Water 50 gallons. 



The mixture can be prepared better by using thirty-two pounds of 

 lime, thirty-two pounds of sulphur, and eight or ten gallons of water, and 

 then diluting to 200 gallons. 



Place the lime in a barrel and add enough water to almost cover it, 

 as soon as the slaking begins, add the sulphur, which should be run 

 through a sieve to break up the lumps. 



Stir constantly and add enough waier to make a thick paste and 

 then, gradually, a thin paste. As soon as the lime is well slaked, cold 

 water should be added to cool the mixture and prevent further cooking. 

 It is then ready to be strained into the spray tank, diluted up to the 

 full formula, and used. 



Care must be taken not to allow the boiling to proceed too far, if the 

 mixture remains hot for fifteen or twenty minutes after the slaking is 

 completed, some sulphur will go into solution and injury to the foliage 

 may result. 



The time of adding the cold water to stop the boiling depends upon 

 the lime. With a sluggish lime all the heat in it may be needed, while 

 with limes that become intensely hot, care must be taken not to allow 

 the boiling to proceed too far. 



SOLUBLE SULPHUR POWDER. 



Soluble sulphur powder, although it is less known than other sulphur 

 compounds, has proven in our tests, of about equal value with com- 

 mercial lime sulphur when used as a Winter spray on dormant trees 

 against the San Jose scale. 



: BORDEAUX MIXTURE. . 



Bordeaux mixture is made of copper sulphate, lime and water. 



These three substances are combined in various proportions, depend- 

 ing upon the kind of plant to be treated. For apples, pears, cherries and 

 plums (except Japanese varieties) the preparation is usually four
