in spraying their trees and bushes, will, if applied 

 liromptly, counteract the disease, but the use of it on 

 house plants is objectionable, because it leaves a dis- 

 colorinf:^ sediment on the foliage. A preparation which 

 will not discolur the leaves is now on the market. It 

 depends for efficacy upon the same copper carbonate 

 that is the basis of Bordeaux mixture. This prepara- 

 tion, which can be bought at agricultural stores, and 

 of most florists, under the name of Copperdine, comes 

 in the form of a paste which can be readily thinned 

 by water and applied as a spray to all parts of the 

 diseased plants. Or they can be dipped in it. The 

 persistent use of this fungicide will soon overcome 

 disease conditions. After your plants become healthy 

 again, use it frequently to prevent a recurrence of the 

 disease.
