Abstract:
Weeds are plant species that adapted to man-made habitats, 1 and are usually innocuous wild plants in their geographical center of origin. 2 They are unintentionally spread and perpetuated by the activities of man and his domesticated animals, including those that have unintentionally become domesticated. Most weeds are herbaceus, but some shrubs and trees, such as Prosopis spp., Acacia spp., and Rubus spp., and cacti, such as Opuntia spp., are extremely noxious weeds in certain habitats. © 1985 by CRC Press, Inc.
