There is no doubt that grassland chemicalization is economically effective. A lot of papers are devoted to assessing the quality of aerosol spraying, but a relationship between the spraying process by technical equipment and the resulting efficiency of spraying in the context of ecological compatibility has not been studied yet. Currently, highly hazardous pesticides are not used. However, there are documented cases of soil phytotoxicity caused by lowand medium resistant pesticides. In order to prevent soil contamination by conservative pesticides, it is required to perform ecological monitoring of aerosol pesticide spraying. For this purpose, the information system software complex has been designed and officially certified. The data for the system database is provided by the Altai regional branch of Russian Agricultural Center. The information system utilizes the data on types of spraying machines, soil types, crop types, chemical agents, and the area under procession.
