COPPER SULPHATE SOLUTION-Copper sulphate, 1 pound 

 Water, 15 gallons. 



Dissolve the copper sulphate in the water, when it is ready for 

 use. This should never be applied to foliage but must be used 

 before the buds break. For fungus diseases. 



PARIS GREEN— Paris Green, 1 pound. Water, 200to 300 

 gallons. 



Repeated applications will injure most foliage, unless lime is 

 added. Paris Green and Bordeaux Mixture can be applied to- 

 gether with perfect safety. 



Use at a rate of 4 ounces of the arsenites to 50 gallons of the 

 mixture. The action of neither is weakened, and the Paris Green 

 loses all caustic properties. For insects which chew. 



HELLEBORE — Fresh white hellebore. 1 ounce, water 3 gal- 

 lons. Apply when thoroughly mixed. This poison is not so ener 

 getic as the arsenites and may be used a short time before the 

 sprayed portions mature. For insects which chew.
