Formaldehyde and aluminum phosphide (AlPO3) at different concentration were used to sterilize Benguet soil. The effects of sterilization of Benguet soil with different concentrations followed by separate inoculation with freeze-dried basidiospores of Pisolithus tinctorius (PERS) Coker and Couch and Rhizopogon sp. on the growth of Pinus kesiya (Benguet pine) seedlings were studied. Results indicated that the two mycorrhizal inoculants were able to infect the seedlings. Infection intensity was moderate for all treatments except for the unfumigated soil inoculated with Rhizopogon sp. which was high. Seedlings inoculated with Rhizopogon sp. grown in unfumigated soil had the highest growth. The experiment showed that sterilization by use of fumigants is not necessary unless presence of soil-born pathogens is detected. Rhizopogon sp. is recommended inoculant for growing Benguet pine seedlings in Benguet soil.
