may be kept somewhat in control by spraying with Bor- 

 deaux mixture (see page 295). 



Insect enemies of potato plants are always abundant. 

 In some years the potato aphid (a tiny plant louse) is 

 very destructive unless vigorously combated with nico- 

 tine sulfate sprays. The potato " bug " (really a 

 beetle, not a true bug) is nearly always present. Dust- 

 ing with Paris green and the use of poison sprays are 

 effective for the larvae of potato beetles, and the adults 

 can be eradicated by hand picking. 



JERUSALEM ARTICHOKE OR GIRASOLE 



This sunflower was a food plant well known to the 



FIG. 160. The Jerusalem artichoke is ornamental as well as useful. Here it 

 is grown on the edge of the garden to serve as a screen for the hen yard in the 

 rear.
