To control the disease of root rot in ginseng nursery, inorganic sulfur solution of 0.1%, 1.0%, and 2.0% wereirrigated by amount of 10 ℓ per 3.3 ㎡ before sowing. On the last ten days of July, Fusarium solani and F. oxysporum weresimilarly detected by 44.8% and 43.8%, respectively, while Cylindrocarpon destructans was low detected by 4.4% in the diseasedseedling. The more sulfur’s concentration was increased, the more soil pH was decreased. Soil pH was decreased from5.87 to 4.59 by the irrigation of sulfur solution of 1.0%. The more sulfur’s concentration was increased, the more electricalconductivity (EC) of soil was increased. EC was increased from 0.27 dS/m to 1.28 dS/m by the irrigation of sulfur solution of1.0%. Irrigation of sulfur solution was effective on the inhibition of damping-off caused by Rhizoctonia solani in ginsengseedling. Control value for damping-off by the irrigation of sulfur solution of 1.0% and 2.0% were 75.7%, and 78.5%,respectively. Growth of leaf was inhibited by the irrigation of sulfur solution of 2.0%. Root weight per 3.3 ㎡ showed thepeak in sulfur solution of 1.0%, while survived-root ratio and root weight per plant were decreased in the level of 2.0%. Survived-root ratio of seedling in sulfur solution of 1.0% was distinctly increased by 4.7 times compare to the control, butcontrol value for root rot was relatively low as 49.2%. Mycelium growth of C. destructans, F. solani, and R. solani weredistinctly inhibited by the increase of sulfur’s concentration in vitro culture using PDA medium.
