The article discusses issues related to the development of pesticide modeling in the environment and its use in order to regulate the circulation of pesticides. As the study of the literature and the author's experience in using mathematical models shows, the main problem and source of errors in modeling is the quality of the input data for the soil block of the model, as well as those characterizing the properties of the pesticide. Using the results of a carefully conducted lysimetric experiment to study the migration of cyantraniliprole outside the soil profile, as well as auxiliary studies, the influence of hydrodynamic dispersion on the behavior of the insecticide and the results of modeling is shown. The parameters of its non-equilibrium sorption by the soil were calculated according to the data of the laboratory experiment investigating the dynamics of decomposition of cyantraniliprole. The article confirms the need to take these processes into account when modeling the transport of pesticides.
