or corn fodder is placed over the tops for pro- 

 tection. 



Small quantities of celery, for table use, can be 

 removed from these trenches from time to time, and 

 stored with the roots in earth in the coolest part of 

 the house cellar. 



Insects and diseases: Insects seldom trouble 

 the celery crop much, although sometimes celery 

 caterpillars (pale green, with black and white marks) 

 are bothersome. Buhach will kill them ; some grow- 

 ers pick them off by hand. Blight, leaf spot, and 

 rust often occur, but may be largely prevented by 

 spraying half-strength Bordeaux mixture on the 

 plants in the seedbed; the spray may be repeated at 

 intervals if necessary when the plants are trans- 

 planted to the field. Rot has already been mentioned 

 (see Blanching). Pithy stalks generally result from 

 too much heat and not enough moisture when the 

 young plants are growing in the field; inferior seed 

 is also often the cause.
