The results of researches on the development of computer technologies of the integrated systems of grain crop protection, the biological base of which is the outstripping information on phytosanitary state of crops and the forecast of its change during vegetation are presented. Based on many years biological material, the data bases and the corresponding normative and inquiry information are formed. The data base on the system of forecasts includes short-term forecast of grain crop development, phytophage number and harmfulness. The data base on insect harmfulness provides with storage, correction and the efficient search of coefficients of harmfulness and the economic thresholds of number, ecological and economic thresholds of expediency of plant protection products application against the dominant pests of spring and winter grain crops taking into account the crop development stage and the varietal peculiarities, the yield being formed, entomophage number, class of the insecticide danger and their side influence on useful fauna. The data base on the evaluation of household, economic efficiency and the ecological safety of integrated systems of plant protection against noxious organisms is formed based on the system of forecast of phytophage harmfulness
