fruit, shown by black specks or blotches upon the skin, 

 the injury extending to the adjacent part of the fruit. 

 Several other fungi attack the leaves, causing shot-like 

 holes or other injurious effects. The bark is attacked 

 by others and the roots commonly suffer from the vexa- 

 tious Crown Galls that attack so many plants. Special 

 care should be taken not to plant any trees showing the 

 characteristic galls of this disease. 



Insect Enemies 



Peach trees are almost as subject to insect attack as 

 they are to those of parasitic fungi. Root, trunk, bark, 

 twig, leaf, and fruit — each is infested 

 by one or more insects. The Peach- 

 tree Borer is probably the most gen- 

 erally destructive of these pests. The 

 adult insect is a small clear-winged 

 moth that deposits eggs on the trunk 

 near the ground. The eggs hatch 

 into whitish larvae that burrow be- 

 neath the bark, often going toward the 

 roots. They cause a gummy exuda- 

 tion at the surface of the holes which 

 is a sign of their presence. After near- 

 ly a year of growth they change to 

 pupae, to change again a little later into moths. The 

 trees should be carefully examined in early summer 

 and in autumn and all borers dug out. 



The San Jose Scale is especially destructive to Peach 

 trees. The infested bark becomes covered with a 

 grayish crust of scales, the insects multiplying so rapidly
