In this article lays the foundation for a program to protect various crops from a complex of diseases. The program is open for inclusion of new modules. As basic components, it uses previously developed models to protect wheat from brown rust, powdery mildew, Septoria and their complex. The new program has increased the detail of calculations based on the model of large-scale distribution of brown rust uredospores in wheat. Significant changes have been made to the basic module for protecting wheat from brown rust, which uses the results of calculations based on a large-scale spread model with a reduced space step and is the basis for comparison with other diseases. The new program was also adapted for the case of poorly defined initial conditions about the actual defeat of wheat by brown rust, powdery mildew and Septoria. Equations are given for estimating wheat damage and crop losses if there is no data on varietal characteristics, regardless of the phase of plant development.
