BORDEAUX MIXTURE 



The following is the official formula for the 

 preparation of this standard fungicide, as sent 

 out by the United States Department of 

 Agriculture : 



In a barrel that will hold forty-five gallons, 

 dissolve six pounds of copper sulphate, using 

 eight or ten gallons of water, or as much as 

 may be necessary for the purpose. Slake four 

 pounds of fresh lime in a tub by pouring water 

 over it until disintegrated. Then add enough 

 water to make it about the consistency of thick 

 cream. Stretch a coarse gunny sack over the 

 head of the barrel containing the copper sul- 

 phate, and strain the lime mixture through it. 

 Then fill the barrel with water. Stir thor- 

 oughly, and the preparation is ready for use. 



Because the quantity seems large, the idea 

 may prevail that the cost must be considerable. 

 Such is not the case, however. The cost per 

 gallon of the mixture will not exceed one cent, 

 as copper sulphate can be bought for seven 

 cents a pound, and lime is about thirty cents a 

 bushel, which will make your four pounds 

 cost less than five cents. 



In all cases it is desirable to use powdered
