Formula A, to be used when the insects are in large numbers and 

 the foliage is known not to be easily injured by it.

FUNGICIDES. 



BORDEAUX MIXTURE. 



Formula. 4 lbs. Copper Sulfate, (Bhie Vitriol). 

 4 lbs. Caustic Lime (Unslaked Lime.) 



Dissolve tlie copper in hot water. (If suspended in a basket or 

 sack in a tub of cold water it will however dissolve in from tw^o to 

 three hours.) 



The lime is then slaked in another vessel adding water slowly that 

 it may be thoroughly slakerl. When both are cool, pour together, 

 straining the lime through a fine mesh sieve or burlap strainer, and 

 thoroughly mix. Before using, add water enough to make 50 gallons 

 of the mixture. 



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 gradually, destroying the spores of the 

 fungi as they are brought in contact with it t)y the surrounding 

 atmosphere. 



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

 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 effectual if made up fresh for each appli- 

 cation. Two or three thorough applications give better results than 

 many light ones.
