Abstract

Forest weeds interfere with productivity of crop (conifer) species reducing yield and quality of produce. Weed control (vegetation management) is considered essential in intensive management of forests. Generally chemical herbicides (2,4-D, glyphosate, hexazinone, simazine, triclopyr) have been found to be most cost-effective tools, but the public is opposed to further use of chemicals in forests in Canada, USA, Sweden. Hence, alternative methods are sought and one such option is development of bioherbicides, i.e. the application of a native pathogen to suppress the competitive ability and reduce the population of forest weeds. A mycoherbicide agent, Chondrostereum purpureum has been investigated and found to be effective against several hardwood weeds. The merits and demerits of biological control strategies and the integration of the bioherbicides with other available options are discussed.
