THE PEACH ORCHARD 



can be destroyed by jarring the tree and catching the adults on 

 stretchers made for the purpose. This is only a partial control. 



Three sprayings besides winter spray are necessary in the South 

 or where curculio are most serious, elsewhere omit poison from 

 No. 1 (See below). These may be made while fighting brown 

 rot. (See below). 



Brown Rot of Peaches.— This is probably the worst fungous 

 disease of the peach and plum (Fig. 148). It is most serious upon 

 the early ripening varieties, but is found to some extent on nearly 



Fig. 147. — Peach borerB have been removed from the left tree and lie in view. Right tree 

 protected with paper so adult moth cannot place her eggs in the trunk. (New Jersey 

 Station.) 



all varieties unless sprayed. Select varieties least affected by the 

 brown rot and always spray. 



Spraying for Brown Rot and Curculio.— The combined spray 

 materials may be used in controlling curculio and brown rot. The 

 beetles come from their winter hiding places to feed on opening 

 buds. In the campaign use 8-8-60 self-boiled lime-sulfur with 

 two pounds paste or one pound powdered arsenate of lead: (1) 

 when the buds are bursting and show a little pink, to kill old 

 spores and some adult curculio; (2) just after petals fall; (3) a 

 week or ten days later. If needed spray for rot four weeks before 

 ripening and for second brood curculio m thp RontV> A.hn«+. two 

 months after petals fall.
