Lawn protection products can potentially result in both transferrable residues on turf and volatile residues in air.  A study was performed to measure the transferrable and volatile residues of trichlorofon and the related primary metabolite dichlorvos (DDVP) following a liquid application to turf with and without irrigation.  This presentation will cover the study design, sample collection and analysis, and the nature of dissipation for both trichlorofon and dichlorvos under typical use conditions.
