The Growing of Peaches 1731 



mediate need for it. On the other hand, it is quickly used and 

 is not there to produce sappy buds in the late summer. 



INSECT ENEMIES 



There are three insects which need attention. The peach-tree 

 borer is kept in control by means of a thorough examination and 

 digging out once a year, preferably in the fall. The San Jose 

 scale has been controlled by thorough spraying with the winter 

 strength of lime-sulphur wash, spraying with the wind and treat- 

 ing each tree from two directions. The plum curculio has been 

 troublesome for a few years past. A spray of two pounds arsenate 

 of lead to fifty gallons of water immediately after the falling of 

 the corolla and again after the calyx falls, has helped very much 

 in lessening the damage caused by this insect. 



DISEASES 



Fungous troubles have been harder to overcome. Brown rot 

 has been a serious menace both on the pistils at the time of 

 blossoming and on the fruit at the time of ripening. The applica- 

 tion of the scale spray within two weeks of the time of blossoming 

 has prevented serious loss and has taken care of the leaf curl at 

 the same time. The use of the Scott formula of " self-boiled " 

 lime-sulphur immediately after the falling of the calyx, again 

 two weeks later, and in the case of late varieties again four weeks 

 before ripening, has prevented serious loss at the time of ripening, 

 and has at the same time, entirely overcome the scab or freckles. 



There is no known remedy for " yellows " and '' little peach." 

 Yellows seem to have been well controlled by digging out and 

 burning as soon as discovered. The same treatment for little 

 peach has kept it fairly well in check but has not overcome it as 

 thoroughly as in the case of the yellows. There is strong evi- 

 dence that neither of these diseases develop as quickly or spread 

 as rapidly in a vigorous, strong orchard as in one that is neglected 

 and poorly fertilized. Good cultivation, thorough spraying and 

 liberal fertilization seem to be the keynote to success in peach 

 production.
