 2;/2 gals, water; add 1 qt. -D

Stir the stock solutions thoroughly. Place i quart 

 of solution A in a wooden pail or glazed earthenware 

 vessel which holds not less than 4 gallons. Add 2 gal- 

 lons of water, and mix well. 



Next, add i quart of stock solution B, and stir 

 thoroughly. Then strain the mixture through cheese- 

 cloth into the tank of the spray pump, and use imme- 

 diately. If a smaller amount of Bordeaux mixture is 

 needed, one-half the amounts mentioned may be mixed 

 for use. Or, if only a very small amount is needed for a 

 single application, it can be made by using 4 ounces of 

 copper sulfate dissolved in 6 quarts of water and 4 

 ounces quicklime (or 5! ounces hydrated lime) slaked
