Dissolve 4 pounds of bluestone (copper sulfate) in a small 

 quantity of water and dilute to 25 gallons. Slake 4 pounds 

 of lime and dilute with 25 gallons of water, thus using the 

 required 50 gallons of water. Next, let the bluestone 

 solution and the lime mixture pass into a third vessel, the 

 two coining together as they enter. The vessels in which 

 the two ingredients are held may be connected with the 

 third by spouts and the liquids brought together as they 

 run into it or they may be dipped with pail or bucket and 

 poured into the third container, a pail of each passing in 

 at the same time. A better mixture results from this method 

 than when one is poured directly into the other. 



If a considerable quantity is to be made, it is not necessary 

 to dilute the lime and bluestone solutions each with one- 

 half the total quantity of water ultimately required ; the 

 solutions should be diluted considerably, however, before 

 they are brought together, and the full dilution made when 

 the mixture is used. Concentrated stock solutions of blue- 

 stone and lime may be made in quantity and held separately 

 until desired for use. 



Other insecticides and fungicides. 



There are other spray mixtures variously recommended 

 for the control of peach insects and diseases. Many of 

 them are proprietary preparations and may have their 

 field of usefulness. The above named insecticides and 

 fungicides, however, have the approval of peach-growers of 

 long experience as well as that of investigators. They 

 may be regarded, therefore, as the standards by which other 

 preparations should be judged.
