 GENERAL PROGRAM FOR TREATMENT OF PLUM. 



PEACH INSECTS. 

 MARCH-APRIL. 



Several species of Eulecanium feed on peach. Most of the 

 species already considered in the plum section and perhaps a few 

 others besides, are also recorded on peach. Treatment for these 

 have been given in Plum Section, page 58. 

 Refer to the apple section for these: 

 Spring Canker Worm, Paleacrita vernata. See pages 39, 40. 

 Fall Canker Worm, Alsophila fometaria. See page 40. 

 San Jose Scale, Asfidiottis ferniciosus. See page 39. 

 Shot Hole Borer, Scolytus rugulosus. See page Si. 

 The Peach Tree Bark Beetle, Phloeotribus liminaris, resem- 

 bles the shot hole borer but is slightly more slender and smaller. 

 The damage resembles that of the shot hole borer. Remedies are 

 the same. 



The Walnut Scale, or Gopher Scale as it is known in the south- 

 ern states, Asfidiotiis juglans-regia, is often a scourge among peach 

 trees. It looks much like San Jose scale, but is considerably larger, 

 and does not become so black in color as some of the stages of San 

 Jose. The same treatment as for San Jose is said to be effective.
