OMMON RAGWEED (Ambrosia artemisiifolia) is a very common weed 
in the eastern half of the U.S. and Canada. It is a native plant and an 
annual, whose oily seeds can live in the soil for many years. The plant 
blooms during August and September and ripens seeds about 1 month later. 
It is most commonly found growing in pastures, grain fields, along roadsides

alfalfa seeds and sometimes in small grain and millet. It rarely causes much 
crop damage except during dry seasons or in pastures where, during July, | 
August, and September it seriously crowds out the pasture plants and is apt 
to taint the milk. The long tapering spikes of male flowers and the much cut 
leaves are very characteristic. It grows to a height of about 3 feet. Its con- | 
trol is largely a matter of preventing seeds from maturing for many years or 
until the seed supply in the soil is exhausted. Plowing grain stubble in | 
August and mowing pastures and meadows before the middle of August will | 
prevent seeds from ripening, as usually after that time frosts will prevent | 
seed production. The leaves and stems are very easily killed by sulfate 
sprays, but the process is rather expensive.
