FORMULAS. 



Bordeaux Mixture. 



Copper sulphate, 6 pounds. 



Quicklime, . 4 n 



Water, 40 gallons. 



Dissolve the copper sulphate by putting it in a bag of coarse cloth and 

 hanging this in a vessel holding at least 4 gallons, so that it is just covered by 

 the water. Use an earthen or woodeti vessel. Slake the lime in an equal amount 

 of water. Then mix the two and add enough water to make 40 gallons. It is 

 then ready for immediate use. For rots, moulds, mildews, and all fungous dis- 

 eases. 



Ammoniaeal Copper Carbonate. 



Copper carbonate, i ounce. 



Ammonia, enough to dissolve the copper. 



Water, 9 gallons. 



The copper carbonate is best dissolved in large bottles, where it will keep 

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



as Bordeaux. 



Copper Sulphate Solution. 



Copper sulphate, . . i 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 

 peaches and nectarines, use 25 gallons of water. For fungous diseases. 



Paris Green. 



Paris green, i pound. 



Water, 250 gallons. 



If this mixture is :o be used upon peach trees, i pound quicklime should 



be added. Repeated applications will injure most foliage, unless Hme 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 with the Bordeaux mixture. Do not use 

 it on peach or plum trees. For insects which chew. 



Hellebore. 



Fresh white hellebore, i ounce. 



Water, 3 gallons. 



Apply when thoroughly mixed. For insects which chew.
