“…As reported previously (Smith and MacHardy 1984;Frank et al 1985;1987;Northover et al 1986), there was a significant loss of captan due to wash-off by rain. The relationships between the loss and the amount of rainfall varied greatly between experiments and fields.…”

“…Several previous studies reported that there was no appreciable loss of captan on tomato fruit (Frank et al 1987), apple and grape (Frank et al 1985), and cherry and peach (Northover et al 1986) under dry conditions. However, large loss of captan was shown under dry conditions in another field study (Smith and MacHardy 1984), which may have resulted from heavy dew.…”

“…Captan is one of the most important fungicides used to control apple scab, particularly when apple mildew is not severe, and is also widely used to control diseases in many other crops (Gilvydis et al 1986;Northover et al 1986;Elzemaity 1988). Many studies have been conducted to investigate captan residues on various crops in relation to physiological and physical factors in laboratory, storage and field conditions (Smith and MacHardy 1984;Frank et al 1985;1987;Elzemaity 1988;Kiigemagi et al 1991).…”

“…First, the general model structure is described. Then, it presents model parameters calibrated specifically for captan, a widely used contact fungicide (Gilvydis et al 1986;Northover et al 1986;Elzemaity 1988). Finally, it evaluates the model predictions against field data of captan residues on apple.…”

A flexible and generic model was developed to predict the decline of residues of a non-systemic pesticide for both single and multi-spray situations as well as for different tree canopy zones. The model predicts not only the average residue levels, but also the confidence interval of the residues through either a deterministic or a stochastic approach. This generic model includes several key aspects of residue fates in the environment: initial deposit, physical loss and growth dilution. The model considers a tree canopy in three distinct zones for which initial deposition of pesticides may differ. In addition to predicting the average residue within each zone, it also estimates the 95 and 99% confidence intervals of residues on individual fruit within each zone. For the purpose of evaluation, this model was parameterized specifically for captan, one of the most important non-systemic fungicides used to control disease in horticultural crops. The observed average initial deposit for each zone was used in the evaluation. The overall correlation between predicted average residues and those observed on apple fruit in two applications was 0.93. Confidence intervals were also predicted accurately.
