RESIN WASH. 



By Professor Koebele. 



This is a summer spray for all scale insects, woolly and green 

 aphis. 



HOW PREPARED. 



Ingredients— Hesin, four pounds. 



Sal soda, tlu-ee pounds. 



Directions — Place resin and sal soda in kettle with three pints 

 of cold water. Use soft or rain water always. Boil or simmer 

 slowly until thoroughly dissolved, when it will look black. The 

 sal soda will adhere to the side of the kettle, and must be scraped 

 down. When it looks dissolved, if there are pieces of resin in the 

 bottom of the kettle, it needs more boiling. "When sufficiently 

 boiled, add enough hot water to make 50 gallons. After adding the 

 water it will become thick, but after boiling again it becomes thin. 

 The above is ready for immediate use, and should be applied cold 

 or only lukewarm. If desired for future use, boil the above amount 

 of ingredients as directed, and add water to make five gallons ; boil 

 until thick. This will stand any length of time, and is always ready 

 for use. When required, use one part or gallon of compound with 

 the following number of gallons of boiling water, and stir thor- 

 oughly when applying: For hop louse, one gallon of compound 

 to nine gallons of water; for woolly aphis, one gallon of compound 

 to seven gallons of water; for San Jose scale, one gallon of com- 

 pound to six gallons of water. The foregoing spray is not inju- 

 rious to the tree, for after three or four days of sunshine it dis- 

 solves and leaves the pores of the bark open,
