| Abstract/Contents: | "The first-year project objectives were to construct, install, and test lysimeters for collecting percolate water in a USGA-type green, to evaluate various methodology practices for pesticide analysis, to develop a quality assurance and control (QA/QC) program, and to engage in preliminary data collection. These objectives have been completed. Stainless-steel lysimeters were installed in a USGA-type green at the University of Florida, IFAS, Ft. Lauderdale Research and Education Center. They were fitted with stainless-steel lines for off-site collection of percolate water. Lysimeter performance was tested in three ways to determine the completeness of sample recovery and to investigate the effect of sample residency time. It was determined that recovery equaled or exceeded 97%. The concentration of fenamiphos (nemacur) remained virtually unchanged after 4 days residency in the collection reservoir, whereas after 1 and 4 days residency, diazinon was only 94 and 0%, respectively, of that injected. A 19-section, 33-page quality assurance/quality control plan was developed to delineate field and laboratory protocols for such items as sampling, calibration, error determinations, chemical analyses, data reduction and validation, corrective actions, and reporting. Methods were validated for determining certain organo-phosphate pesticides in percolate water, thatch, soil, and grass clippings. In a preliminary field study, fenamiphos applied to bermudagrass (Cynodon sp.) turf was observed primarily in thatch over a 7-day period. Fenamiphos in the underlying soil generally was only 10% that in the thatch, and seven days after application, fenamiphos in thatch was only 10% that observed two days after application." |
