Fifteen PGPF (plant growth promoting fungi) isolates were selected from 728 fungal isolates collected from rhizosphere of zoysiagrass in Korea. Identification of the 15 isolates was based on their morphological characteristics. They were classified as Gliocladium sp. (n = 1), Penicillium sp. (n = 5), Trichoderma sp. (n = 3), Fusarium sp. (n = 3), and unidentifed species (n = 3). Of the 15 isolates, six (PF-31, PF-136, PF-238, PF-255, PF-395, PF- 420) significantly promoted the growth of tomato seedlings, and three (PF-31, PF-101, PF-255) also promoted the growth of hot pepper and two (PF-31, PF-225) also promoted the growth of cucumber. The 15 PGPF isolates were divided into 4 groups based on root colonizing ability. Isolates PF-17, PF-101 and PF-225 were included in the group 1, which had high root colonizing ability.
