1 erson who would be prepared to spray under contract, by the acre, or at a 

 stated figure per tree. If this system of combating fungous and insect enemies 

 was introduced, it would obviate much of the prejudice and inconvenience now 

 < nnected with the work, and spraying would probably in a few years, to the 

 great benefit of orchardists, become the general practice. 



SPRAYING MIXTURES. 



1. Diluted Bordeaux Mixture. 



Copper Sulphate 4 lbs. 



Lime 1 4 lbs. 



Paris Green 4 oz. 



Water 50 gallons. 



This may be prepared by dissolving, in a barrel, four pounds of powdered 

 pper sulphate. In another vessel slake four pounds of fresh lime with as 

 many gallons of water. Spread a piece of coarse sacking, held in place by a 

 hoop, over the top of the barrel in which the copper sulphate has been dissolved. 

 Strain through this the creamy mixture of lime and water. Paris green may then 

 be added, after which the barrel should be filled with water. This forms an 

 excellent insecticide as well as fungicide and therefore useful to destroy codling 

 worm, bud moth, and canker worm. It should be used soon after being 

 prepared. 



2. Ammoniacal Copper Carbonate. 



Copper Carbonate 5 oz - 



Ammonia . . 2 qts. 



Water 50 gallons. 



This is more expensive than the former, is more easily applied and is used 

 - 1 substitute, especially in the case of grapes, where the Bordeaux mixture 

 Jit, by adhering to the fruit, injure its sale 



It is prepared by dissolving the copper carbonate in the ammonia and 

 diluting with water to fifty gallons. The concentrated solution should be poured 

 into the water. Care should be taken to keep the ammonia tightly corked in 

 y ass or stone jars. 



TREATMENT OK APPLE AND PEAR SPOT. 



i. Before growth begins in spring, spray with a solution of copper sulphate, 

 ■ lb. to fifty gallons of water. On no account should this be applied after the 

 iliage has appeared, as it will severely injure it. 



2. Just before the blossoms open spray with diluted Bordeaux mixture 

 (No. 1). Repeat this after the blosM.ni:> have fallen, and make a third applica- 

 tion two or three week> afterwards. If the season is wet and rainy a later 

 •lication may be advisable.
