just before applying. Tliis application is to prevent brown-rot, scab, 

 and the curculio. 



About one month before the fruit ripens, spray once more as directed 

 above. 



Recent experiments by the Horticultural Department have demon- 

 strated the efficiency of the sulphur dust applied ten days to two weeks 

 before harvest to prevent the development of brown-rot during the 

 ripening period or directly after, while the fruit is in transit, and before 

 it reaches the consumer. (For further details see Experiment Station 

 Special Bulletin No. 115).

PEACH TREE BORER. 



Dig out by hand early in the spring or late in the fall at points 

 where the gumming shows. Sterilize the knife with 2 to 5 per cent 

 compound solution of cresol after finishing with each tree, in order to 

 prevent the spreading of crown-gall which is often present. In order 

 to facilitate the removal of the larvae of "worms" many growers prac- 

 tice MOUNDING OR DITCHING. It seems to be of advantage to change 

 the level of the soil around the base of the tree, either raising the level 

 by making a mound of which the tree is the center, or lowering the 

 level by digging away the soil in June and allowing the soil to be worked 

 back by cultivation. Undoubtedly it is easier to pull away the mound 

 to expose the injured crown than to dig out the soil. The mound is 

 later replaced after the wounds have dried. On the other hand, most
