Bordeaux Mixture 



Copper Sulphate 4 pounds 



Quicklime 6 



Water gallons 



Place the copper sulphate in a grain bag and suspend 

 it in a barrel containing about 25 gallons oT water, in 

 which way it will dissolve over night. Slake~~a quantity 

 of freshly burned lime in as much water as it will take 

 up and no more. Such slaked lime can conveniently be 

 kept in a barrel sunk in the ground and the lime kept 

 covered with water to prevent drying. Of this slaked 

 lime take about 10 pounds and stir it up in about 25 

 gallons of water. Then strain it and pour it into another 

 barrel simultaneously with the copper sulphate solution 

 while stirring vigorously. The barrel should be filled up 

 to the 50 gallon mark and the mixture is ready for use. 



In spraying with Bordeaux mixture the beneficial 

 fungi that keep the scale insects in check are destroyed 

 as well as that which cause injury to the tree. For this 

 reason scale insects multiply fast after spraying with 

 Bordeaux mixture and it should never be used except in 

 connection with scale sprays or closely followed by an 

 application of such. It should be well understood that 

 Bordeaux mixture does not destroy scale nor any other 

 kind of insect, neither do soaps or oil emulsions destroy 

 fungi.
