" Curl " of Peach Leaves. 



57 



nearly all May checked the growth of the peach foliage and 

 made it unhealthy and liable to this fungoid attack. 



Remedies and Methods of Prevention. 



In the early stages of this disorder when there are only a 

 few leaves infected, these should be picked off and burnt, in 

 order to prevent the spores of the fungus from spreading 

 over the leaves and shoots of neighbouring peach trees. 



Infected trees should be sprayed with bouillie bordelaise, 

 «ven if the leaves showing infection have been picked off, 

 as the spraying will prevent any spores that may be on the 

 leaves and shoots from germinating. The bouillie should be 

 made with 3lbs. of pale sulphate of copper and 3lbs. of lime 

 to 50 gallons of water. The sulphate of copper must be 

 dissolved in a vessel in cold water, and the lime, which must 

 be pure and fresh, slaked in another vessel. The contents 

 ■of the two vessels should be poured together into a tub, and 

 the proper quantity of water added. The bouillie should be 

 put on in a fine spray by means of a knapsack machine so 

 that every part of the foliage, shoots, and stems, may be 

 covered with the blue liquid. This mixing and spraying 

 must be supervised and carried out carefully or the foliage 

 may be scorched ; but, with a bouillie of the strength given 

 above, there ought to be no injury whatever. In America 

 much stronger solutions are employed without harm. When 

 the foliage gets old the strength of the bouillie may be 

 increased ; four pounds of sulphate of copper and a similar 

 quantity of lime may then be used.
