Weed in fallow fields and wastelands in the High Ranges
Ageratum conyzoides (Billygoat-weed, Chick weed, Goatweed, Whiteweed; Ageratum conycoides L., Ageratum obtusifolium Lam., Cacalia mentrasto Vell.) is native to Tropical America, especially Brazil. Herb 0.5–1 m. high, with ovate leaves 2–6 cm long, and flowers are white to mauve.[1]
In Vietnamese, the plant is called cứt lợn (Pig Feces) due to its growth in dirty areas.[2]
Uses[edit]
As a medicinal plant, Ageratum conyzoides has limited uses due to its toxicity. It is also an insecticide and nematicide.[3]
Toxicity[edit]
Ingesting A. conyzoides can cause liver lesions and tumors.[4][5] There was a mass poisoning incident in Ethiopia as a result of contamination of grain with A. conyzoides.[6] The plant contains the pyrrolizidine alkaloids lycopsamine and echinatine.
Weed risk[edit]
A. conyzoides is prone to becoming a rampant environmental weed when grown outside of its natural range. It is an invasive weed in Africa, Australia, Southeast Asia and the USA.[7][8] It is considered a moderate weed of rice cultivation in Asia.[9]
