Abstract
Analytical methods for methiozolin in soil, water and turfgrass were established and dissipation patterns of methiozolin in soil and turfgrass were elucidated. Analysis was done using a high performance liquid chromatography with an ultra violet detector at the wavelength of 280 nm after extraction with acetone, liquid-liquid partition with dichloromethane, and a solid phase extraction purification. Limit of determination and Limit of quantitation were 1.0, 0.5, 1.0 ng, and 0.001, 0.1, 0.01 mg/kg for water, turfgrass, and soil, respectively. Recovery rates of methiozolin from soil, water, and turfgrass were ranged 87.5~111.3, 92.8~97.4, and 78.2~98.5 %, respectively. The turfgrass and soil samples were collected at 0, 1, 4, 7, 14, 30, 45, and 60 after spray on green area in golf course. Residues of methiozlolin were not translocated to lower soil layer but detected only in turfgrasses and root area of turfgrass. Half-lives of methiozolin in turfgrass were 10.7 days and 8.8 days in soil from root area.
