Ambrosia artemisiifolia, the Common Ragweed is the most widespread plant of the genus Ambrosia in North America. It is also known as Annual Ragweed, Bitterweed, Blackweed, Carrot Weed, Hay Fever Weed, Roman Wormwood, Stammerwort, Stickweed, Tassel Weed, Wild Tansy, and American Wormwood. It is native in North America
Description
Ambrosia artemisiifolia, Common Ragweed, grows to about one meter-3 feet in height. Its wind-dispersed pollen is a strong allergen to many people with hay fever. Common Ragweed emerges in the late spring and sets seed in later summer or fall.
Invasive species
It is invasive species in some European countries [1], and in Japan, where it is known as butakusa —pig grass.[2]
Common ragweed is a very competitive weed and can produce yield losses in soybeans as high as 30%. Control with night tillage reduces emergence by around 45%. Small grains in rotation will also suppress common ragweed if they are overseeded with clover. Otherwise, the ragweed will grow and mature and produce seed in the small grain stubble. Several herbicides are effective against common ragweed, although resistant populations are known to exist.[3]
Phytoremediation
Ambrosia artemisiifolia is used in phytoremediation projects, removing heavy metals such as Lead.
