In preparing this bulletin, our formulas and directions are based 

 upon the numerous experiments made at this station ; the successful 

 practice of practical fruit growers in various sections of this and 

 other states, and a careful review of the work of other stations during 

 the past season in protecting their fruit and garden crops from the 

 attacks of insects and fungi. 



As these generally appear about the same time it is found ecouom}- 

 wherever possible, to combine the fungicides and insecticides, there- 

 by materially reducing the cost. 



For general purposes we consider the Bordeaux mixture the best 

 fungicide until the fruit reaches the size when it will be disfigured by 

 it, after which the ammoniacal carbonate of copper should be used. 

 We also consider Paris "reen the best insecticide. 



FORMULAS. 



BORDEAUX MIXTURE. 



4 lbs. Copper Sulphate or Blue Vitriol. 

 4 lbs. Fresh Unslaked Lime, 

 25 to 50 gallons of water. 



Directions for Making. 



Dissolve the copper sulphate in two gallons of hot water in a 

 wooden tub or pail, and let it stand until cool, or suspend in a basket 

 or sack in a tub or pail of cold water. Slake the lime with water 

 enough to make a thin whitewash. When both are cool, pour the 

 lime through a strainer of gunny cloth or fine wire sieve, into the 

 copper solution and mix thoroughly. 



When ready to use it, add water enough to make (a) 25 gallons, 

 or (b) 50 gallons of the mixture, and again strain before pouring 

 into the barrel or knapsack pump. Application should be made 

 through a Vermorel or adjustable nozzle which will give a fine spray 

 or mist. 



In making this mixture care must be taken that the lime thoroughly 

 precipitates the copper, for if much of the copper still remains in 

 solution it will burn the foliage, especially that of the peach and 

 cherr}', and sometimes the plum. 



To avoid this danger, obtain from your druggist a small quantity 

 of yellow prussiate of potash and dissolve it in water in a small
