Répartition géographique d'une plante adventice introduite au Togo : "Chromolaena odorata" (L.) King & Robinson (syn. : "Eupatorium odoratum" L.)

Résumé

Many introduced plant species, either by chance or for agricultural purpose, are raising ecological problems. It is the case of Chromolaena odorata (L.) King & Robinson, a weed whose distribution in Togo is described. As this weed is likely to expand in several areas, and as it is noxious to pastures, it should be contained by cultural or chemical means. The authors advocate control based on regular surveys, using preventive measures at an early stage of invasion, including outrooting and fire.
