204 PEACH LEAF CURL: ITS NATURE AND TREATMENT. 



apply sprays for the prevention of curl is in dry, calm weather, and 

 during- the middle of the day, in order to avoid dew or frost upon the 

 limbs as much as possible. 



(14) Of nearly 200 peach and nectarine varieties considered with a 

 view of determining their comparative susceptibility to curl, it was 

 found that very few were wholly free from the disease and that some 

 were ver}^ subject to it. Some of the choicest v arieties, as the Elberta 

 and Lovell, are seriously affected, but it has been demonstrated that a 

 single winter treatment will prevent the disease upon even these varie- 

 ties. It ma}^ be thus fairly claimed that the spraying methods recom- 

 mended will save to the peach industry some of its finest varieties, as 

 well as result in the saving of foliage and crops already indicated.
