SPRAYING. 



The usual methods used for combating this scale 

 are by means of sprays made of oils of various kinds 

 and of resin compounds. 



Fed Oil. Various brands of ''red oil" mixture are 

 upon the market. The usual methods of mixing are 

 to take equal quantities of rainwater and red oil, 

 place the oil in a bucket or spray pump, add the 

 water slowly, stirring or churning vigorously the 

 while. When, the oil and water have thoroughly 

 emulsified, add twenty times as much water as there 

 is emulsion .that is, forty times the amount of oil 

 used and mix up well in the barrel of the spraying 

 outfit. This mixture may be considered as full 

 strength, and a stronger solution than this is not 

 advisable. The chief thing to see to at mixing is 

 that the oil and water emulsify thoroughly, which 

 will not be the case if the water is at all hard, and 

 should it be in this consition it should first be softened 

 by dissolving a handful of washing soda in it before 

 mixing it with the oil. 



The usual time for using red oil spray is in the 

 summer months, generally during the months of 

 January and February, and to guard against sun- 

 scald of the leaves and fruit is best applied during 

 a cool spell during these months. Should the weather 

 be warm to hot when the spraying is being done, a 

 solution of one gallon of oil to 50 gallons of water 

 will be found strong enough to kill the scale. 



Kerosene Emulsion is preferred by some growers 

 for spraying purposes. This is made up in the pro- 

 portion of 2 gallons of kerosene, \ Ib. soap, 1 gallon 

 water. The soap is dissolved by boiling in the gallon 

 of water. The water is taken off the fire, and the 

 kerosene added slowly, the mixture being churned 

 with a spray pump for ten minutes or so, until a 

 stable emulsion is formed. Another gallon of warm 

 water is then added, bringing the solution up t> 

 4 gallons.
