Abstract
The effects of methyl bromide soil sterilization and inoculation with spores from ground sporocarps of Rhizopogon luteolus on the growth of Pinus radiata seedlings is described. It is concluded that although Rhizopogon luteolus may not be the most efficient mycorrhizal fungus available to South African foresters, the ease with which it can be introduced into practice, together with the improvement in growth that it can achieve, warrants its use. Sample material is available to anyone wishing to try the original source. Screening of other Rhizopogon species and other strains of R. luteolus to check for greater efficiency are recommended.
