NOTE: Because peach trees and some varieties of 
plums are suscep- 
tible to arsenical injury, lead arcenate should not be used with- 
out adding the zinc-sulfate-lime mixture, Sanitary measures such 
as picking up and burying the dropped frits at frequent inter- 
vals, cleaning rubbish about the orchard and removing the 
mummified fruits from the tree in the fall, will aid in controlling 
plum curculio and brown rot. 
Peace tree bores are the most serious pests of peaches. They 
tunnel between the bark and wood of the crown, trun, and 
upper roots of the tree. Peach tree bores are controlled by ap- 
plying crystalline paradichlorobenzene (PDB) in a ring around 
the trunk about Sept. 1. One ounce of crystals to a well-growr 
tree is placed in a ring about the base of the tree and coveret 
with soil. Care must be taken not to place the chemical in 
contact with the tree. On heavy ground the soil should be re- 
moved in about three weeks and replaced with ‘resh soil. DO 
NOT USE THIS TREATMENT ON TREES LESS THAN FOUR 
VWeRHoe@LD: 
Where only one or two trees are infested, the borers can he 
readily removed with a wire if the dirt is first removed from 
around the base of-the tree
