Abstract
Tolclofosmethyl (TCFM) is heavily and annually applied to the turf soils of most golf courses in Gyeongju to control the fungi known to cause the disease brown patch. The soil samples used for the experiment was collected three weeks after the annual application at the end of May in the year 2002. The preliminary results obtained from this study demonstrated that the repeated field annual applications of TCFM to the turf soils of a golf course located in Gyeongju city in the southern area of Korea showed the enhanced degradation of the parent compound TCFM, especially in the surface (0～15 cm) soil rather than the shallow subsurface (15～30 cm) and deep subsurface (30～45 cm) soils, compared to the corresponding surface (0～15 cm) and shallow and deep subsurface (15～30 cm and 30～45 cm) soils of the untreated plot. It appears that microorganisms in the soil may be involved in the enhanced degradation of TCFM.
