pounds of lime slaked in 40 gallons of water. 

 Four gallons of each will make a basis for 50 

 gallons of Bordeaux mixture. 



The only disadvantage to Bordeaux mixture 

 is that it discolors the plant, it being a "blue 

 whitewash"; and those who object to the dis- 

 coloration often use the ammoniacal carbonate 

 of copper, rather than the sulphate. But this 

 is not so sure a remedy, neither does it stick 

 so well. It is made by dissolving an ounce of 

 carbonate of copper in a pint of water and add- 

 ing it to a quart of ammonia. If the amjnonia 

 is strong, use only enough to thoroughly dis- 

 solve the copper, otherwise it will injiire the 

 plants. Cork the mixture tightly and when 

 wanted for use, add from 8 to about 20 gallons 

 of water to each ounce of the copper. This is 

 used principally on fruit that is nearly grown, 

 or upon purely ornamental plants, to avoid dis- 

 coloration. 



Bordeaux cannot cure internal diseases of 

 the plants. These may be caused by insect 

 borers at the roots, or by some incurable bac- 

 terial trouble, and in this case there is nothing 

 you can do but root up the affected plants and 

 destroy them, and then study out how you can 

 prevent its happening again. 



Sprays for insects usually consist of some f onn
