and it should be diluted with water as required. For same purpose as 

 Bordeaux. 



Copper Sulphate Solution. — Copper sulphate, one pound; water, 

 fifteen 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 peaches and nectarines use twenty-five 

 gallons of water. For fungous diseases. 



Paris Green. — Paris green, one pound ; water, two hundred and fifty 

 gallons. If this mixture is to be used upon peach trees, one pound quick- 

 lime should be added. Repeated applications will injure most foliage, 

 unless lime is added. Paris green and Bordeaux can be applied together 

 with perfect safety. The action of neither is weakened, and the Paris 

 green loses all caustic properties. For insects which chew. 



London Purple.— This is used in the same proportion as Paris green, 

 but as it is more caustic it should be applied with the lime, or mth the 

 Bordeaux mixture. Do not use it on peach or plum trees. For insects 

 which chew. 



Hellebore. — Fresh white hellebore, one ounce; water, three gallons. 

 Apply when thoroughly mixed. For insects which chew. 



Kerosene Emulsion. — Hard soap, one half pound; boiling water, one 

 gallon; kerosene, two gallons. Dissolve the soap in the water, add the 

 kerosene, and churn with a pump for five to ten minutes. Dilute ten to 

 fifteen times before applying. For insects which suck, cabbage worms, 

 and all insects which have soft bodies. — Cornell University.

 dealing with a biting (eating) insect or with a sucking insect. Upon this
