An ecologist defines weeds as: 'plants growing entirely or predominantly in situations (that are) disturbed by man without being deliberately cultivated'
© G.R. Dixon 2007. Vegetable Brassicas and Related Crucifers (G.R. Dixon)
(Baker, 1965). This definition includes all plant types, not solely the flower-forming angiosperms, although these comprise the great majority of weed taxa. The world weed flora mainly contains plants from relatively few, highly advanced families (Table 6.1) (Hill, 1977) which thrive in the very fertile soils developed for crop production. Such plants are opportunistic and have evolved to exploit the crop environments created by man which differ markedly from natural ecosystems (Fogg, 19 75).
