CROP PRODUCTION 



Insect Enemies 



Examine peach trees for signs of borers. Dig out all 

 that can be found. 



Examine the bark to see if any scale insects are present. 



After the fruit sets examine the young peaches for the 

 crescent marks of the plum curcuHo. If they are abun- 

 dant it may be advisable to jar the trees and catch the 

 curculios on sheets spread beneath.
