36 horticulturist's rule-book. 



Peach-Louse or Aphis {3Iyzus Persicce, Sulzer). — A small 

 insect feeding upon the young leaves, causing them to curl 

 and die. < 



Bemedies. — Kerosene emulsion. Soap-and-soda wash. 

 Soap-water. Soap and tobacco. 



Peach-Tree Borer {Sannixia exitiosa, Say). — A whitish 

 larva, about three-fourths inch long when mature, 

 boring into the crown and upper roots of the peach, 

 causing gum to exude. 



Preventive. — Make a mound about the tree in early 

 summer, a foot high, and remove it in September ; the 

 moth then lays her eggs about the top of the mound, and 

 the tender larvee are killed by exposure to the weather. A 

 coat of asbestos roofing applied about the base of the tree is 

 recommended as a preventive. Apply washes as for apple- 

 tree borers. Paint the crown of the tree with ordinary 

 paint, to which Paris green has been added. All preven- 

 tives are unsatisfactory, however, and the only safety is — 

 Bemedy. — Dig out the borers in late fall and early spring. 



Peach-Twig Moth (Anarsia lineatella, Zeller). — The larva 

 of a moth, a fourth inch long, boring in the ends of the 

 shoots ; it sometimes attacks the apple and strawberry 

 roots. 



Bemedy. — Burn the infested twigs. 



Pin-hole Borer (Scolytus rugidosus, Ratz). — A black 

 beetle about a tenth of an inch long, boring into the trunk 

 and branches of peach, plum, apricot, and other trees. It 

 is thought to prefer weak or unhealthy trees. 



Bemedy. — Burn the affected trees or parts. Keep the 

 trees strong and vigorous. 



Plum-Curculio. — See under Plum. 



Red-legged Flea-Beetle (Haltica rvjipes, Linn.), — A flea- 

 beetle feeding on the leaves of peach trees, often in great 

 numbers. 



Bemedies. — The insects fall at once upon being jarred, 

 and sheets saturated with kerosene may be used, upon 

 which to catch them. Spray with Paris green.
