Abstract

Unwanted vegetation (weeds) in reforested areas interfere with productivity of the crop species and reduce the yield and quality of the produce. Even though chemical herbicides are used to reduce competition and interference by forest weeds, growing political and environmental concerns have necessitated the search for alternative methods. Biological control (use of sheep, natural herbicides, allelopathy and bioherbicides) offers great promise but no successful bioagent is currently available to replace the herbicide option. A new bioherbicide approach is being experimented; the merits and demerits of this method together with the special features of forests weeds are discussed.
