Wild Carrot, Bird's Nest, or Devil's Plague. 



Daucus carota (L.) 



This is a biennial, naturalized from Europe, with a deep, strong 

 tap root, a bristly stem, and much divided leaves like the cultivated 

 carrot. The clusters of flowers are in compound umbels which re- 

 semble bird-nest cavities. 



Time of flowering, July- September. 



Time of seeding, August-December. 



Dispersal — by seeds carried by wind and animals. 



Eradication. Spudding is quite effective when the roots are cut 

 before blossoming the first season. When the field becomes badly 

 infested it should be plowed and cultivated and treated to a hoed 

 crop, as described for the treatment of Blue weed (page 64).
