| Abstract |
A mathematical model was developed to predict the transport and effects of a pesticide in an orchard ecosystem. The environmental behavior of azinphosmethyl was studied over a two-year period in a Michigan apple orchard. Data were gathered for the model on initial distribution within the orchard, influence of rainfall on vertical movement, loss via runoff, and effects on selected orchard invertebrate populations. Following model development, a third year of field data were collected for comparison with model projections. Mean squared errors for the comparison of predicted vs observed residue data indicated good predictions of azinphosmethyl fate within the tree and grass/broadleaves layers. Prediction of pesticide dynamics within the litter/moss and soil layers was much more variable. |
