An offer of the existing expert systems (ES) for crop production in our country is presented. It was established that the recommendation decision support systems in plant protection are ES-like, since they comprise components typical of ES. The DSS formulate recommendations solving problems concerning justification of protective treatments. Thus such DSS behave similarly to the ES. The availability of the information from the ES in plant protection is still scant in our country. It is necessary to develop new ES for the most important crops. Interpretation of the EU provisions allowed stating the need of presenting the integrated pest management issues in a wider scope of the integrated crop production. The multifaceted scope of these issues calls for a multidisciplinary handling of the ES development: cooperation of agronomists, phytopathologists, plant-protection specialists, meteorologists, economists, agricultural advisers, farmers as well as specialists in databases, software engineering, artificial intelligence, etc.
