126 THE PLUM IN KANSAS. 



The spraying of plums and cherries to protect them from the black- 

 knot fungus, as stated, can be carried on with profit in all sections 

 where this disease threatens to interfere seriously with the profitable 

 cultivation of these fruits. 



BORDEAUX MIXTURE. 



Copper sulphate 6 pounds. 



Quicklime 4 " 



Water 40 gallons. 



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

 ing this in a vessel holding at least four gallons, so that it is just covered by the 

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

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

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

 eases. 



AMMONIACAL COPPER CARBONATE. 



Copper carbonate 1 ounce. 



Ammonia enough to dissolve the copper. 



Water 9 gallons. 



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

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

 Bordeaux. 



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 he oppHed to foliage, but must he used before tJie buds break. 

 For peaches and nectarines, use twenty-four gallons of water. For fungous dis- 

 eases. 



PARIS GREEN. 



Paris green 1 pound. 



Water 250 gallons. 



If this mixture is to be used upon peach trees, one pound of quicklime should 

 be added. Repeated applications will injure most foliage, unless lime is added. 

 Paris green and Bordeaux can he eipplicd together with perfect setfety. 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 1 ounce. 



Water 3 gallons. 



Apply when thoroughly mixed. For insects which chew. 



KEROSENE EMULSION. 



Hard soap =} pound. 



Boiling water 1 gallon. 



Kerosene 2 " 



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.
