THE VEGETABLE GARDEN 



The amount of copper sulphate should be re- 

 duced to 4 pounds for peaches and Japanese plums, 

 and some have used but 2 pounds each of copper 

 sulphate and lime to 50 gallons, with excellent re- 

 sults. Employ the weaker formula whenever the 

 normal proves too strong. 



AMMONIACAL COPPER CARBONATE. Make a 

 paste of 5 ounces of copper carbonate with a little 

 water, and dilute 3 pints of ammonia (26 Beaume) 

 with 7 or 8 volumes of water. Add the paste to the 

 diluted ammonia, stirring till dissolved, and add 

 enough water to make 45 gallons. Allow it to settle 

 and use only the clear blue liquid. This mixture 

 loses strength on standing. 



POTASSIUM-SULPHIDE SOLUTION. Dissolve % 

 to 1 ounce of potassium sulphide (liver of sulphur) 

 to 1 gallon of water. 



COPPER-SULPHATE SOLUTION. Dissolve 1 pound 

 of copper sulphate (blue vitriol) in 15 to 25 gal- 

 lons of water. Never apply this to the foliage. Use 

 only before the buds break. For peaches and nec- 

 tarines, dilute with 25 gallons of water. 



FORMALIN. Dilute 1 pound (1 pint) with 50 

 gallons of water, sprinkle on grain, stirring thor- 

 oughly and leave in piles for several hours for grain
