REMEDIES 



Kerosene emulsion: 



Whale-oil soap (or any hard soap shaved fine) 



Water 



Kerosene (coal-oil) 



^/z pound. 



1 gallon. 



2 gallons. 



Dissolve the soap in the water while it is boiling over a fire. 

 When the soap is well dissolved, remove the solution a safe 

 distance from the fire and add it to the coal-oil. Churn the 

 mixture, using a strong force pump, for a few minutes until it 

 has a creamy consistency. If the emulsion is well made the 

 oil will not rise to the surface on standing. This is the stock 

 solution and will keep for several weeks. When wanted for 

 use dilute one part of the stock solution with ten parts of water. 

 Dip the plants in the emulsion before setting out in the field or 

 apply as a spray to infested plants in the field. When applied 

 as a spray in the field do not treat the plants when the fruit-bud 

 is forming — do the spraying either before the fruit-bud starts 

 to grow or after it is partly grown. Use only enough of the 

 mixture to wet thoroughly the scales. If too much is used it 

 will collect at the base of the leaves or run down about the 

 crown and it is apt to injure the plant. 



Resin wash: 



Resin pounds. . 5 



Caustic soda (crude 78 per cent.) " ..1 



Fish oil (whale oil soap) " . . \ 



Water gallons. .20 



Full directions for the preparation of resin wash are given in 

 Bulletin 3 of the Hawaii Experiment Station. 



In using the resin wash follow the directions given for the 

 kerosene emulsion. 



The emulsion, being a more permanent mixture, more easily 

 prepared and equally as efficient, recommends its use in place 

 of the resin wash; however, the use of either mixture is a point 

 for the planter to determine to his own satisfaction.
