Government regulators of agricultural pesticides use multidisciplinary computer models with which they make product licencing decisions. Hydrology engineering and chemistry components are integrated into the multidisciplinary models. Although the scientific quality of the hydrology components is reasonably good, the scientific quality of the chemistry component does not match this good quality. These models often use chemically meaningless parameters and assumptions that are not supported by experiments. During the past 25 years chemical kinetics and mechanisms based on experiments and stoichiometry have been published for most agricultural pesticides in soil and water. Thus, the chemistry components should now be replaced with those that use the kinetics and mechanisms currently available. They should next be continuously upgraded as the chemical mechanisms research evolves.
Government regulators of agricultural pesticides base legally binding decisions on computer predictions. The multidisciplinary computer models used for this have two integrated components. One is hydrology engineering and the other is chemistry. The good scientific quality of the hydrology engineering component is not matched by the quality of the chemistry component. They often use chemically meaningless parameters and assumptions not based on experiments. Kinetics and mechanisms models that are based on conventional chemical kinetics, stoichiometry, and experiments have been published for pesticides in soil and water. The chemical components should now be prepared with these concepts and methods, and integrated with the hydrology engineering in new types of multidisciplinary models.
