Dissolve the copper sulphate (bluestone) in twenty-five gallons of 

 water. Slack the lime slowly so as to get a smooth, thick cream. 

 After thorough slacking, add twenty-five gallons of water. When 

 lime and bluestone are dissolved, pour rapidly together and mix 

 thoroughly. Strain through a coarse cloth. 



Mix fresh for each time. Use for molds and fungi generally. 

 Apply in fine spray with a good nozzle.

BORDEAUX-PARIS-GREEN MIXTURE

AMMONIACAL COPPER CARBONATE 



Copper carbonate 5 oz. 



Ammonia (26 Baume') about 3 pts.

Dissolve the copper carbonate in smallest possible amount of 

 ammonia. This solution may be kept in stock and diluted to 

 proper strength as needed. 



Use this instead of the Bordeaux Mixture after the fruit has 

 reached half or two thirds of the mature size. It leaves no spots 

 as does the Bordeaux. 



COST OF SPRAYING 



Sulphate of copper costs about ten to fifteen cents a pound. 

 Formalin may be bought from seventy-five to ninety cents a pound. 

 You can make the Bordeaux Mixture at a cost of a little less than 

 one cent a gallon.
