IO4 THE NEW ONION CULTURE 



comparatively little influence after the disease was 

 well established. 



The question has been asked whether bulbs at- 

 tacked by the V ermicularia can safely be used for seed 

 onions, and it may be said that this can be done with 

 perfect safety, provided that the fungus has not at- 

 tacked them sufficiently to have induced rotting; since 

 as a rule the surface layers only are affected, the bulb 

 being otherwise sound. No infection of the seed or 

 seed stalks is to be feared ; but the old bulb will be 

 likely to harbor the fungus during the summer, and 

 communicate it to market onions if planted near them.
