Abstract/Contents:"The research project initially examined the persistence and mobility of four commonly used pesticides: Pendimethalin (Lesco 60 DG, Pre-M®) herbicide, metalaxyl (Subdue®) fungicide, chlorpyrifos (Dursban™), and isazophos (Triumph®) insecticides in turfgrass/soil systems. It was also of interest to determine the relative distribution of these pesticides among the verdure, thatch, and soil components with time after application...Based on observed disappearance rates, overall average time to 50% of the original applied pesticide degraded (DT₅0) values were 16, 12, 10, and 7 days for matalaxyl, pendimethalin, chlorpyrifos, and isazofos in the turf/soil profile. These pesticides appeared to degrade more rapidly in the turfgrass environment than typically reported for other agronomic cropping systems. Variability in pesticide residue amounts for each soil depth among the turf/soil core profiles indicated non-uniform dissipation in the soil."
