CONTROL 



This plant is eaten as greens by 

 many people and makes a most pal- 

 atable early spring dish. It is gen- 

 erally found on low lands and be- 

 comes a pestiferous weed only when 

 these lands are seeded to wheat, oats, 

 clover, or some other uncultivatt'd 

 crop. Hand jjulling of small patches, 

 jdowing the land before the flower 

 stalks put up, sowing only clean seed, 

 and otherwise preventing the plants 

 from maturing seeds are the leading 

 methods of control.
