Control ; 



X-Disease has been successfully brought under control by the following 

 practices . 



(1) Removal of diseased peach trees as soon as they are found - they will be 

 unproductive and die eventually anyway. Cutting out diseased branches 

 in an attempt to save the tree does not work. 



(2) Killing chokecherries for some distance around the orchard. This can be 

 done easily with the modern effective chemical weedlcillers . Also killing 

 other cherries such as pin or bird cherry which may be carriers. 



(3) When starting a new orchard, killing out the chokecherries and other wild 

 cherries in the area and then planting disease- free plants obtained from 

 a reliable nursery.
