ABSTRACT

Biological control in agricultural systems is now a well established and accepted technology for the control of a wide range of pests including nematodes (Mankau, 1980), weeds (Julien, 1987) insects (Mackauer et al., 1990), as well as microbial plant pathogens (Cook and Baker, 1983; Hornby, 1990). The technology is not as advanced, however, for the biological protection of processed wooden products even though successful systems have been studied or commercially used for the protection of growing trees and stumps against basidiomycete fungi including Heterobasidium annosum (Rishbeth, 1963; Ricard, 1970), Chondostereum purpureum (Mercer and Kirk, 1984a,b), Phellinus weirii (Nelson et al., 1985), Ophiostoma ulmi (Atkins and Fairhurst, 1987), Phellinus tremulae (Hutchinson et al., 1994) and Armillaria luteobubalina (Nelson et al., 1995).
