— This very common 

 and well-known dis- 

 ease causes swollen 

 growths on the 

 branches which are 

 at first olivaceous in 

 color, but finally be- 

 come deep black and 

 very hard and brit- 

 tle. It will spread 

 over the greater part 

 of a tree, interfere 

 with its growth and 

 finally cause its 

 death. 



Treatment. — 

 The diseased parts 

 should be cut out 

 and burned and the 

 trees should be 

 sprayed with lime- 

 sulphur in the spring 

 before the opening 

 of the buds. (See 

 table for plum.)
