From page 7...
... For example, repeated mowing can select weeds with predominantly prostrate growth forms; perennial cropping systems (e.g., orchards) often select perennial weeds; and weed species typically shift from predominantly grass weeds to broadleaf (dicot)

From page 8...
... Resistance is not: o Restricted to herbicides; continuous use of any practice will select for best-adapted weeds resulting in evolution of resistant biotypes or succession to adapted species. Principles from biology that underpin resistance management include: o Increased selection pressure causes resistance to evolve.
