Peaches in Western New York.

the tree in June, and the fruit, deprived of nourishment, may also 

 fall. lycaf curl, the curculio and lack of pollination are the chief 

 causes of the " June drop " of peaches. 



There have been few definite experiments in the treatment of 

 the peach curl, but there is reason to believe that one or two very 

 thorough sprayings with sulphate of copper or with Bordeaux mix- 

 ture before the buds swell, will lessen its spread. A few experi- 

 ments of this kind in var- 

 ious parts of the country 

 have been successful ; 

 amongst these was one 

 made by Henry Lutts, of 

 Youngstown, N. Y. 



Root-gallsViY>- 

 on the peach, as 

 shown in Fig. 

 12, have been 

 serious in one 

 orchard in Nia- 

 gara count3^ 

 and they are 

 probably widely 

 distributed in 

 the state. These galls occur 

 both upon the small roots 

 several feet from the trunk , 

 and also in large masses just 

 under and about the crown. 



Trees thus affected 

 stop growing and as- 

 sume a yellowish and 

 sickly look, and they 

 may be mistaken 

 for trees suffering with the yellows by persons not familiar 

 with that disease. The cause of this disease is wholly un- 

 known. It occurs from the Atlantic to the Pacific, and Atkin- 

 son^ considers it to be the same as the Wurzclkropf of the Ger- 



/ / . L eaf- curl of the peach.
