This extensive resource provides you with in-depth information about agricultural weeds and the best ways of managing them. It includes a general discussion of weed biology, plus a reference section that describes the identification, ecology and management of 63 most common and difficult-to-control weed species in crop and forage production systems. The ecological approach to weed management seeks to first understand the biology and behavior of problem weeds and then develop an integrated set of control strategies.
