The present study simulates degradation of pesticides in the soil of the apple orchard based on a half-life of active ingredients. Throughout the paper, pesticide degradation is described by exponential regression equations. The calculation of the content of active substances has been carried out in dynamics during one year for two pest control system models, which involve 11 active ingredients − insecticides and fungicides.
