Abstract
Residue data from field samples were used to parameterize a model for azinphosmethyl attenuation and movement in an orchard ecosystem. Rates of attenuation within, and movement between, specified orchard compartments were determined under various rainfall regimes. The output of this model was structured to allow the estimation of the time course of azinphosmethyl exposure to ground-dwelling invertebrates. Root mean squared errors for the comparison of the model predictions with an independent set of residue data indicated good prediction of azinphosmethyl fate within the tree, grass-broadleaves layers, and soil layers. Prediction of pesticide dynamics within the litter-moss was much more difficult. Model predictions estimate that under dry conditions 25% of the daily loss of azinphosmethyl from the orchard trees is due to movement to other parts of the orchard. Greater movement is predicted under rainfall conditions.
