Abstract
A continuous simulation model that considers interactions of pesticides in surface runoff (in water and on eroded sediment), advection in percolating water, molecular diffusion, dispersion, uptake by plants, sorption to soil, and biological and chemical degradation is described. The model was partially performance tested for aldicarb using data from field sites in New York, Florida, and Wisconsin. The model was successfully tested with observed data at the sites using selected values for 1st-order degradation rate constants and sorption coefficients. The model was successfully calibrated to the observed data at the New York site using selected values for 1st-order degradation rate constants and sorption coefficients. Calibrated parameter values were within the reported range of measured values, suggesting the model effectively simulates relevant processes affecting the pesticide's movement. An example of model application for a hypothetical pesticide applied to wheat in Nebraska is provided.
