      abstract     = {Calculation of pesticide volatilization from plants as an
                      integral component of pesticide fate models is of utmost
                      importance, especially as part of PEC(predicted
                      environmental concentrations) models used in the
                      registration procedures for pesticides. A mechanistic
                      approach using a laminar air-boundary layer concept to
                      predict volatilization from plant surfaces was compared to
                      data obtained in a wind-tunnel study after simultaneous
                      application of parathion-methyl, fenpropimorph, and
                      quinoxyfen to winter wheat. Parathion-methyl was shown to
                      have the highest volatilization during the wind-tunnel study
                      of 10 days $(29.2\%).$ Volatilization of quinoxyfen was
                      about $15.0\%,$ revealing a higher volatilization tendency
                      than fenpropimorph $(6.0\%),$ which is attributed to
                      enhanced penetration of fenpropimorph counteracting
                      volatilization. Predictions of the boundary-layer approach
                      were markedly influenced by the selected values for the
                      equivalent thickness of the boundary layer and rate
                      coefficients, thus indicating that future improvements of
                      the approach will require a deeper understanding of the
                      kinetics of the underlying processes, e.g.
                      phototransformation and penetration. The boundary-layer
                      volatilization module was included in the European
                      registration model PELMO, enabling simultaneous calculation
                      of volatilization from plants and soil. Application of PELMO
                      to experimental findings were the first comprehensive PEC
                      model calculations to imply the relevant processes affecting
                      the postapplication fate of pesticides.},
