Abstract A. conyzoides is an annual erect herb reported as an invasive, noxious weed in agricultural lands and as a coloniser of open fields and degraded areas, causing crop yield reductions and affecting biodiversity (Kohli et al., 2006; GISD, 2016; PIER, 2016). It is also a host of pathogens and nematodes that affect crop species (BioNET-EAFRINET, 2016). It is listed as invasive throughout Asia; in Kenya, Mayotte, Morocco, Reunion, Tanzania, South Africa and Uganda in Africa; California (USA) in North America; Cuba in the Caribbean; Easter Island in South America; and in much of Oceania (Oviedo-Prieto et al., 2012; BioNET-EAFRINET, 2016; Encylopedia of Life, 2016; GISD, 2016; PIER, 2016). It is also known to be invasive in Ethiopia, Malawi, Rwanda, and Zambia.
