each, may be prepared atone time and they will keep in good con- 

 dition for a week or two but they should never be put together until 

 ready to be used. Before mixing, the lime solution should be 

 thoroughly stirred and diluted. 



The copper solution will retain ils strength and value indefinitely, 

 but the lime mixture is never as good as tinthin an hour or tivo of the 

 time it is made and we would caution those purchasing the prepared 

 Bordeaux mixture, not to expect as satisfactory results as from the 

 fresh home-made mixture which is also much cheaper. 



The active agent in this mixture is the copper, the lime being used 

 simply to hold it in place upon the foliage and branches of the plants 

 sprayed. Here it is given up with each rain, destroying the spores of 

 the fungi as they are brought in contact with it by the surrounding 

 atmosphere. 



Should the lime be air slaked at all more than four pounds may be 

 needed as it will have lost much of its strength. 



This fungicide is recommended as more satisfactory than any 

 other, from the fact that it adheres a long time to the branches, buds 

 and leaves and seldom causes any injury to the foliage. 



It has been found more effective if made up fresh for each appli- 

 cation. Two or three thorough applications give better results than 

 many light ones. 



When both fungous growths and insects attack a crop, Paris green 

 should be applied with the Bordeaux, as in a combined state both 

 are as effective as if used singly, one-half of the labor being saved and 

 the lime preventing injury to the foliage by the Paris green. 



DILUTE COPPER SULFATE SOLUTION. 



After the fruit has nearly matured it is often disfigured by the 

 adhesion of the Bordeaux mixture especially the plum, peach, cherry 

 and grape and in place of this we would advise the use of copper 

 sulfate 2 to 4 oz. to 50 gallons of water. The foliage of many plants 

 will stand a much stronger solution, but this is as concentrated as 

 can be generally used. 



It must be remembered that this -solution will be washed off by 

 every hard rain, and to keep the copper on the foliage or fruit during 

 frequent rains will sometimes require spraying every day. This has 

 been done in some cases and with profit, for often without it the
