While the rusty-colored root is common in ginsengs culture and, often results in a severe economic loss, the major factors have not been found. This study was focused on the determinatino of a potential relationship between rusty root and endophytic bacteria. The number of endophytes was 9.6×10¹~1.5×10² cfu/g fw in normal ginseng roots compared to 3.7×10∨6~5.1×10∨7 cfu/g fw in rusty ones. Of 31 isolates from rusty ginseng roots, twenty-four isolates repeatedly induced severe to moderate rust on root while seven isolates induced slight rust.
